The Atlantic sturgeon has five rows of bony plates known as scutes. But to corroborate this development and to ensure its further success, existing age and telemetry data need to be analyzed now and taken into consideration. After laying their eggs, females leave their spawning areas, while males remain there until autumn. Males weigh up to 90 pounds and females weigh up to 160 pounds. In North America, they range along the Atlantic Coast from the Gulf of Mexico to Newfoundland, including the Great Lakes and the St. Lawrence, Missouri, and Mississippi Rivers, as well as along the West Coast in major rivers from California and Idaho to British Columbia. The species gathers in areas between Québec City and Petite-Rivière-Saint-François to rear and feed their young, and potentially so adults can spawn, rest and feed as well. Subadults and adults live in coastal waters and estuaries when not spawning, generally in shallow (10-50 m depth) nearshore areas dominated by gravel and sand substrates. Distribution: Description: Four smaller plates usually as 2 pairs, between anal fin and caudal fulcrum, first pair may overlap base of anal fin, second pair may look like one plate; 6-9 plates, mostly in pairs, behind dorsal fin; dorsal plates 7-16; lateral plates 24-35; usually to 10 feet and 300 pounds. The Atlantic sturgeon has a brown, tan or bluish-black body and a whitish belly. Atlantic Sturgeon is a biologically significant species with its ancestry dating back some 200 million years. The largest fish to be captured in the St. Lawrence River (160 kg or 350 lb) was estimated to be about 60 years old. For example, Atlantic sturgeon mature in South Carolina rivers at 5-19 years of age, in the Hudson River at 11-21 years, and in the Saint Lawrence River at 22-34 years. Three Hydrolab sonde units will be placed near the river's bottom to collect data over at least eight months of the year.This time series data will include measurements on oxygen, pH, temperature and salinity and others. Their populations have since declined due to human factors, such as overfishing and water pollution. Sturgeons supported an important fishing industry from colonial times to the early 20. The Atlantic Sturgeon is a biological and historical superlative. Dredging could constitute a major threat, especially in juvenile feeding areas. They range as far north as Ungava Bay, Labrador, into the Gulf of St. Lawrence, southward on the Atlantic coast to Florida and along the coast of the Gulf of Mexico. Males probably reproduce every 3 to 4 years, while this interval is longer for females. Atlantic Sturgeon spawn in relatively shallow fresh water over rocky substrate, preferring depths of one to three metres with a strong current. The National Oceanic and Atmospheric Administration.

COSEWIC Assessment Date and Status Change: May 2011 Females can lay up to 2 million eggs, which are large and black and stick to the bottom of the river. Please note that this information is provided for general information purposes only. In 1898, commercial landings peaked in New York at 510,000 pounds. It is the largest and longest-lived aquatic organism in the Atlantic Slope rivers of North America, and played a critical role in the establishment of the Jamestown settlement. Lawrence River Atlantic sturgeon is the most northerly spawning population within the spe-cies’ range. Gravel Augmentation at Spawning Habitats in the Oconee and Ogeechee Rivers of GeorgiaThe robust redhorse (Moxostoma robustum), a species that had been lost to science for about 150 years, was discovered on the Oconee River in 1991. Wild populations subsequently found in the Savannah River (Georgia/South Carolina) and Pee Dee River (North Carolina) have been augmented by stocking in other areas of Georgia and South Carolina. Thus, a broad range ofbiological data is needed to facilitate restoration and management of this valuable species (Smith 1985; Smith and Clugston 1997). They spawn in moderately flowing water (46-76 cm/s) in deep parts of large rivers. However, no Atlantic sturgeon have been recorded in Florida waters since 1900. Centuries of overfishing, habitat alteration and pollution have eradicated this “founding fish” from many Chesapeake Bay tributaries. Atlantic sturgeon are similar in appearance to shortnose sturgeon (Acipenser brevirostrum), but can be distinguished by their larger size, smaller mouth, different snout shape, and scutes. COSEWIC Reason for Designation: This large-bodied, slow-growing, and late-maturing fish consists of a small breeding population spawning within a relatively small area. Atlantic sturgeon are found on the east coast of North America and range from New Brunswick, Canada, down to the eastern coast of Florida. Figure 1 – Where Atlantic sturgeon are found along the United States. Several species provide caviar from eggs. Mature Atlantic Sturgeon spend time in estuaries and smaller bays as it is thought to help in transitioning between salt and fresh water. When the first settlers came to North America, the Atlantic sturgeon was in great abundance. Its long, hard snout has an upturned tip, with four sensory barbels on the underside of its sn… However, the connectivity of many of these springs to the main rivers has been diminished by drought and sediment. Atlantic Sturgeon occur in rivers, estuaries, nearshore marine environments and the shelf regions to at least 50 m depths along the Atlantic coast of North America. Accessed 18 Mar. Atlantic Sturgeon, Acipenser oxyrhynchus. The largest Atlantic sturgeon ever recorded was caught in Canada. Text taken from the NOAA Fisheries Office of Protected Resources online fact sheet, November 2013 and Chesapeake Bay Program online fact sheet. Once larvae begin migrating downstream they use benthic structure (especially gravel matrices) as refuges. National Recovery Program | Credit: NMFS. It grows slowly, eventually reaching 5 to 6 feet in length. There is generally faster growth and earlier age at maturation in more southern populations. The Atlantic Sturgeon is an anadromous species that resides and matures in the sea, but spawns in freshwater, which also serves as juvenile rearing habitat. Atlantic sturgeon are currently present in approximately 32 of these rivers, and spawning occurs in at least 20 of them. Atlantic Sturgeon … COSEWIC History of Status Designation: Designated Threatened in May 2011. “Together, they comprise the southernmost portion of the Atlantic sturgeon’s range.

Southeast Map of Atlantic sturgeon critical habitat for Greater Atlantic and Southeast Regions. Spotlight on James River Atlantic Sturgeon Habitat Restoration, VirginiaA lack of clean, hard substrate has been noted as a limiting factor for the restoration of many anadromous species in the James River. To address these issues, a study was conducted to provide information on habitat use, age distribution, reproductive status, and sea­ sonal movements ofadult Atlantic sturgeon in two South Carolina rivers. The Atlantic Sturgeon, St. Lawrence populations, is mainly found east of Trois-Rivières, into the Estuary and past the Gulf of St. Lawrence, into the Atlantic up until Ungava Bay in the north, and along the northeastern coast of Newfoundland in the south. Historically, Atlantic sturgeon ranged along the Canadian and U.S. Atlantic Coast from Labrador to Florida. The dredging of river channels is a practice that can destroy or suffocate the sturgeon eggs located on objects in the benthic layer of the river. This, combined with their slow rate of maturity, damming of their spawning rivers and historic commercial fishing pressure, has caused the species to become very rare. The following summaries are some of the on-the-ground habitat restoration projects that benefit Atlantic sturgeon and that have been funded by the Eastern Fish Habitat Partnerships (FHPs) with support from USFWS or NOAA and implemented through state and/or local partnerships: Deadman's Island Restoration ProjectLead by the City of Gulf Breeze, this project will restore coastal barrier habitat on Deadman's Island. Habitat | Adults range from six to eight feet in length. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Due to overfishing, the abundance of natal populations is much less than historic levels, but breeding populations still exist in at least 22 U.S. rivers from Maine to Georgia and in several more in Canada. Because of its large size, the female Atlantic Sturgeon is extremely fertile. The Atlantic Sturgeon is a large-bodied, slow-growing and late-maturing anadromous fish, which lives and grows in brackish, salty water, but spawns in fresh water. Description | Juveniles may overwinter in freshwater or move into estuaries when temperatures drop in the fall. If sturgeon are recovering here, then they’re likely recovering in other rivers as well.” The project has three primary objectives, the first of which is to find out how many sturgeon are being born in the Ogeechee and Satilla rivers. Sturgeon, any of about 29 species of fishes of the family Acipenseridae (subclass Chondrostei), native to temperate waters of the Northern Hemisphere. Atlantic Sturgeon are among the oldest fish species in the world. The Gulf sturgeon occurs on Florida’s west coast. Taxonomy Group: Fishes Atlantic sturgeon have been aged to 60 years. For the most up to date and accurate list of species listed under the Species at Risk Act, please see the Justice Laws Website. 2000; Collins They have also been known to exist in northern Canadian rivers in Labrador and Newfoundland and also in the Northern Gulf of … Threats | It spends most of its life in the ocean and coastal areas. Native to North America, its range extends from New Brunswick, Canada to the eastern coast of Florida. To match resources, the restoration project has been subdivided into 10 reaches. ‘Spawning Atlantic sturgeon are showing up in rivers where they were never thought to exist.’ Commenting on the prognosis elsewhere in the range, Delaware State University’s Fox offers this: “Spawning Atlantic sturgeon are showing up in rivers where they were never thought to exist. The National Marine Fishereies Service has administration authority for this species an dit was recently listed as federally threatened in the Gulf of Maine and federally endangered throghout its remaining range. Atlantic sturgeon can live for more than 60 years. RANGE: Atlantic sturgeon are currently present in 32 of the 38 historical rivers known to have sturgeon populations along the Atlantic coast of the United States. Movement/Migration and Spawning: Sturgeons are anadromous, meaning they live in the ocean and spawn in freshwater rivers. These rivers are essentially the canaries in the mine. Geographic Range: According to the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service, historically, Atlantic sturgeon were present in approximately 38 rivers in the United States from St. Croix, ME to the Saint Johns River, FL, of which 35 rivers have been confirmed to have had a historical spawning population. Crabtree Swamp Habitat RestorationThe restoration of Crabtree Swamp is an innovative, "first of its kind" project, in which a previously channelized drainage basin is being returned to a blackwater hardwood swamp in which the floodplain is being recreated via earthmoving and replanting into functional habitat for fish, invertebrates and other wildlife. Long distance migrations away from spawning rivers are common. A failing perched culvert will be restored with an open‐arch culvert in the summer of 2012. The potential re-emergence of spawning Atlantic sturgeon in the Connecticut Riverwould be a major and highly welcome achievement of decades of conservation efforts by state agencies. Females take nearly 20 years to mature. The Atlantic Sturgeon is recognized by a particular arrangement of the scutes and an elongate body with a slightly upturned snout. Atlantic sturgeon are listed as five distinct population segments with those that hatch out in Gulf of Maine rivers listed as threatened, and those that hatch out in other U.S. rivers listedas endangered. It measured 14 feet long and weighed 811 pounds. Under the Endangered Species Act of 1973, critical habitat may be designated by NOAA Fisheries for the conservation of threatened and endangered species under its jurisdiction. They are long-lived (reaching ages up to 70 years) and are anadromous, migrating from the ocean into coastal estuaries and rivers to … Other/Previous Names: Atlantic Sturgeon (Great Lakes / St. Lawrence populations) Whereas the European sturgeon has a quite narrow range of preferred temperatures, the Atlantic sturgeon tolerates a wider range of spawning temperature and generally is more flexible in regards to temperature (Ludwig & Gessner, 2007; but compare Williot et al., 2011). Occurs occasionally in Bermuda, French Guiana and N. Gulf of Mexico. Scientific Name: Acipenser oxyrinchus Sturgeons were abundant when English settlers arrived in the Bay region in the 1600s. Patches of hard substrate and 3-D reefs will be created in stocking areas, thus establishing quality habitat for red drum at this early life stage. They tend to travel alone, rather than in schools. Documents. Among the species showing improvement is Atlantic sturgeon, whose range stretches from Florida to eastern Canada. Spawning occurs from April-June in the freshwater river where the fish was born. Juveniles begin their migration once they have reached 80 to 120 cm. 2 in Bladen County, North Carolina. The gravel augmentation is expected to benefit invertebrates, including mussels, as well as anadromous species such as striped bass, American shad, and Atlantic sturgeon. Most species live in the ocean and ascend rivers to spawn in spring or summer; a few others are confined to fresh water. Wild populations subsequently found in the Savannah River (Georgia/South Carolina) and Pee Dee River (North Carolina). Improved Red Drum Habitat through Community-based Oyster Reef Habitat RestorationLittle has been attempted to improve the habitat to ensure survival of stocked red drum fingerlings in SC waters This project will create additional oyster reefs in stocking areas. Marine and fresh water pollution was also identified as a potential threat to the Atlantic Sturgeon's habitat. The fish can reach sixty years of age, fifteen feet in length and over eight hundred pounds in weight. As with other Atlantic sturgeon populations along the Atlantic coast (Bain et al. In the meantime, they are available on request from the COSEWIC Secretariat. In some southern rivers a fall spawning migration may also occur. In the St. Lawrence River, males reach sexual maturity between the ages of 16 and 26, while females may reach maturity around age 27 or 28. Oconee River Gravel Bar Habitat Enhancement (Phase I)The robust redhorse (Moxostoma robustum), a species that had been lost to science for about 150 years, was discovered on the Oconee River in 1991. COSEWIC Range: Quebec, Atlantic Ocean Native Distribution Map for Acipenser oxyrinchus (Atlantic sturgeon) modeled future range map based on IPCC A2 emissions scenario www.aquamaps.org, Aug. 2013. Distribution: Western Atlantic: Hamilton River, Labrador, Newfoundland, Canada to northeastern Florida,USA. The fish then only typically returns to its spawning ground every 3-5 years. COSEWIC Status: Threatened Atlantic sturgeon leap completely out the water, making a loud splash which can be heard half a mile away and possibly further under water. Genetic information suggests both regional and population-level structure and the existence of two designatable units (DUs): St. Lawrence River and Maritimes DUs. SARA Status: No schedule, No Status This project will promote the population of Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus) and other anadromous fishes of the Chesapeake Bay through the restoration of spawning and nursery habitat. Cape Fear River Fisheries Enhancement ProjectThis project, lead by Cape Fear River Watch, will restore .5 acres of fish habitat by placing approximately 1,000 tons of crushed granite rock (over 2,000 cubic yards, .5 acres downstream of lock and dam #2) in the Cape Fear River below Lock & Dam No. Atlantic sturgeon are anadromous fishthey are born in freshwater, then migrate to the sea and back again to freshwater to spawn. PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. It has no scales, but five rows of bony plates, called scutes, cover its head and body: one along the back, one on either side and two along the belly. Atlantic sturgeon habitats have increased vulnerability since they inhabit areas that are at risk of dredging. COSEWIC Status Criteria: D2 Sturgeons remain in the river system during summer and return downriver in fall. Habitat Use: Atlantic sturgeon are "anadromous"; adults spawn in freshwater in the spring and early summer and migrate into "estuarine" and marine waters (saltwater) where they spend most of their lives. Photo | Web. Now, thousands of are believed to be there, according to Virginia Commonwealth University scientists. Periodic or grab sampling utilized to date may miss suspected short-term degradations of water quality associated with water flows of storm events. Shoreline and Spartina Marsh stabilization along the Atlantic Intracoastal Waterway, South CarolinaThis project will rehabilitate tidal marsh areas experiencing degradation from boat traffic along the Intracoastal Waterway, within the ACE Basin National Estuarine Research Reserve, by constructing natural breakwaters using oyster reefs. The Atlantic Sturgeon lives and grows in brackish and salty water, but spawns in fresh water. It is likely that cold, clean water is important for proper larval development. The species is very particular about the water quality and depth as well as the gravel quality of its spawning sites. itudinal range similar to that of Atlantic sturgeon, and juveniles grow faster at higher latitudes, a difference in growth that has reproductive implications for this short- lived species (Conover and Present, 1990). Shortnose sturgeon are listed under the Endangered Species Act (ESA) as an endangered species throughout their range. According to the Committee on the Status of Endangered Wildlife in Canada, Atlantic Sturgeon found in Canadian waters form two distinct populations: the St. Lawrence and Maritimes populations. Protection | Atlantic sturgeon (Acipenser oxyrhnchus) are ancient fish dating back at least 70 million years, and can be found along the entire Atlantic coast from Florida to Labrador, Canada. The impact will be many fold as other organisms will utilize the habitat and oyster population and water quality improvements will be recognized. Atlantic sturgeon range from the St. Johns River in Florida to the St. Lawrence River in Canada. Once hatched, juveniles stay in their natal river for as long as six years before moving into open waters and eventually the ocean. COSEWIC Status Report on the Atlantic Sturgeon Acipenser oxyrinchus in Canada (2011-09-09), Response Statement - Atlantic Sturgeon, St. Lawrence populations (2011-12-08), COSEWIC Annual Report - 2010 - 2011 (2011-09-09), Atlantic Sturgeon Consultations on listing under the Species at Risk Act (St. Lawrence populations) (2014-11-17), Access Government of Canada activities and initiatives, Response Statement - Atlantic Sturgeon, St. Lawrence populations, Atlantic Sturgeon Consultations on listing under the Species at Risk Act (St. Lawrence populations). They have five major rows of dermal "scutes". The current population size of Atlantic Sturgeon, St. Lawrence populations, has never been formally established but the population of mature adults is estimated at between 500 and 1000 individuals. Most juveniles remain in their river of birth (natal river) for at least s… Spawning occurs in mid-river between February and July. Atlantic sturgeon can grow to approximately 14 feet (4.3 m) long and can weigh up to 800 lbs (370 kg). The main threats to the Atlantic Sturgeon are commercial fishing and the degradation and loss of habitat. This young Atlantic sturgeon was raised at a national fish hatchery and stocked into the Hudson river to help boost local populations back in 1994. Range and Distribution The range of the East Coast subspecies of Atlantic sturgeon (A. oxyrinchus) extends from the Hamilton River in Labrador, Canada and from northern Quebec to southeastern Florida. Males do not reach sexual maturity until they are at least 10 years old. 2014. Juveniles usually reside in estuarine waters for months to years. Habitat Restoration to Benefit Rare Species and Natural Communities in the Altamaha River WatershedCool water springs feeding major coastal rivers in Georgia provide critical thermal refuges during summer for diadromous fishes such as striped bass. Quick Links: | They were around during the Cretaceous period, when dinosaurs roamed the earth. Sturgeons are prehistoric fish that have existed for more than 120 million years. To know if this species is protected by provincial or territorial laws, consult the provinces' and territories' websites. Biologists study Atlantic sturgeon to better understand their needs for survival and to determine how healthy they are in the … The Atlantic Sturgeon feeds primarily on benthic invertebrates, although large juveniles and adults also feed on small fish. These are the largest anadromous fish on the East Coast of the United States, reaching as much as 14 feet () and 800 pounds, though the largest fish seen in modern times is around 400 pounds. Sturgeons are the largest fish native to the Chesapeake Bay. The Atlantic sturgeon is a long-lived, estuarine dependent, anadromous fish.
Credit: NMFS. A 148-kg female was reportedly captured in the St. Lawrence River with 41.4 kg ovaries containing about 3,700,000 eggs. The Atlantic sturgeon has five rows of bony plates known as scutes. But to corroborate this development and to ensure its further success, existing age and telemetry data need to be analyzed now and taken into consideration. After laying their eggs, females leave their spawning areas, while males remain there until autumn. Males weigh up to 90 pounds and females weigh up to 160 pounds. In North America, they range along the Atlantic Coast from the Gulf of Mexico to Newfoundland, including the Great Lakes and the St. Lawrence, Missouri, and Mississippi Rivers, as well as along the West Coast in major rivers from California and Idaho to British Columbia. The species gathers in areas between Québec City and Petite-Rivière-Saint-François to rear and feed their young, and potentially so adults can spawn, rest and feed as well. Subadults and adults live in coastal waters and estuaries when not spawning, generally in shallow (10-50 m depth) nearshore areas dominated by gravel and sand substrates. Distribution: Description: Four smaller plates usually as 2 pairs, between anal fin and caudal fulcrum, first pair may overlap base of anal fin, second pair may look like one plate; 6-9 plates, mostly in pairs, behind dorsal fin; dorsal plates 7-16; lateral plates 24-35; usually to 10 feet and 300 pounds. The Atlantic sturgeon has a brown, tan or bluish-black body and a whitish belly. Atlantic Sturgeon is a biologically significant species with its ancestry dating back some 200 million years. The largest fish to be captured in the St. Lawrence River (160 kg or 350 lb) was estimated to be about 60 years old. For example, Atlantic sturgeon mature in South Carolina rivers at 5-19 years of age, in the Hudson River at 11-21 years, and in the Saint Lawrence River at 22-34 years. Three Hydrolab sonde units will be placed near the river's bottom to collect data over at least eight months of the year.This time series data will include measurements on oxygen, pH, temperature and salinity and others. Their populations have since declined due to human factors, such as overfishing and water pollution. Sturgeons supported an important fishing industry from colonial times to the early 20. The Atlantic Sturgeon is a biological and historical superlative. Dredging could constitute a major threat, especially in juvenile feeding areas. They range as far north as Ungava Bay, Labrador, into the Gulf of St. Lawrence, southward on the Atlantic coast to Florida and along the coast of the Gulf of Mexico. Males probably reproduce every 3 to 4 years, while this interval is longer for females. Atlantic Sturgeon spawn in relatively shallow fresh water over rocky substrate, preferring depths of one to three metres with a strong current. The National Oceanic and Atmospheric Administration.

COSEWIC Assessment Date and Status Change: May 2011 Females can lay up to 2 million eggs, which are large and black and stick to the bottom of the river. Please note that this information is provided for general information purposes only. In 1898, commercial landings peaked in New York at 510,000 pounds. It is the largest and longest-lived aquatic organism in the Atlantic Slope rivers of North America, and played a critical role in the establishment of the Jamestown settlement. Lawrence River Atlantic sturgeon is the most northerly spawning population within the spe-cies’ range. Gravel Augmentation at Spawning Habitats in the Oconee and Ogeechee Rivers of GeorgiaThe robust redhorse (Moxostoma robustum), a species that had been lost to science for about 150 years, was discovered on the Oconee River in 1991. Wild populations subsequently found in the Savannah River (Georgia/South Carolina) and Pee Dee River (North Carolina) have been augmented by stocking in other areas of Georgia and South Carolina. Thus, a broad range ofbiological data is needed to facilitate restoration and management of this valuable species (Smith 1985; Smith and Clugston 1997). They spawn in moderately flowing water (46-76 cm/s) in deep parts of large rivers. However, no Atlantic sturgeon have been recorded in Florida waters since 1900. Centuries of overfishing, habitat alteration and pollution have eradicated this “founding fish” from many Chesapeake Bay tributaries. Atlantic sturgeon are similar in appearance to shortnose sturgeon (Acipenser brevirostrum), but can be distinguished by their larger size, smaller mouth, different snout shape, and scutes. COSEWIC Reason for Designation: This large-bodied, slow-growing, and late-maturing fish consists of a small breeding population spawning within a relatively small area. Atlantic sturgeon are found on the east coast of North America and range from New Brunswick, Canada, down to the eastern coast of Florida. Figure 1 – Where Atlantic sturgeon are found along the United States. Several species provide caviar from eggs. Mature Atlantic Sturgeon spend time in estuaries and smaller bays as it is thought to help in transitioning between salt and fresh water. When the first settlers came to North America, the Atlantic sturgeon was in great abundance. Its long, hard snout has an upturned tip, with four sensory barbels on the underside of its sn… However, the connectivity of many of these springs to the main rivers has been diminished by drought and sediment. Atlantic Sturgeon occur in rivers, estuaries, nearshore marine environments and the shelf regions to at least 50 m depths along the Atlantic coast of North America. Accessed 18 Mar. Atlantic Sturgeon, Acipenser oxyrhynchus. The largest Atlantic sturgeon ever recorded was caught in Canada. Text taken from the NOAA Fisheries Office of Protected Resources online fact sheet, November 2013 and Chesapeake Bay Program online fact sheet. Once larvae begin migrating downstream they use benthic structure (especially gravel matrices) as refuges. National Recovery Program | Credit: NMFS. It grows slowly, eventually reaching 5 to 6 feet in length. There is generally faster growth and earlier age at maturation in more southern populations. The Atlantic Sturgeon is an anadromous species that resides and matures in the sea, but spawns in freshwater, which also serves as juvenile rearing habitat. Atlantic sturgeon are currently present in approximately 32 of these rivers, and spawning occurs in at least 20 of them. Atlantic Sturgeon … COSEWIC History of Status Designation: Designated Threatened in May 2011. “Together, they comprise the southernmost portion of the Atlantic sturgeon’s range. Photo credit: Virginia Institute of Marine Sciences. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. Part of the Atlantic sturgeon’s scientific name. Restoring Diadromous Fish Passage and Habitat to Shoreys Brook, MaineThis project, located in South Berwick, ME will restore approximately 800 feet of habitat for diadromous fish species and enhance approximately 4.3 miles of habitat in Shoreys Brook.  A partially‐breached dam was completely removed and the stream bed was restored to its approximate original condition. The expected results of the project include: increased fish habitat, stabilized shoreline, improved water quality, and increased public awareness.
