New York State Department of Environmental Conservation (DEC) has reported a milestone in the restoration of the Genesee River following the collection of a spawning female lake sturgeon in the lower Genesee for the first time in more than 50 years.
The announcement took place with partners along the banks of the Genesee River in Monroe County. On May 25th, 2021, Dr. Dawn Dittman and the field crew from the U.S. Geological Survey’s (USGS) Tunison Laboratory of Aquatic Science netted the 61-inch, nearly 70-pound female lake sturgeon. DEC began stocking lake sturgeon into the Lower Genesee River in 2003, as part of the State’s efforts to support the species’ recovery.
The discovery of the spawning lake sturgeon in lower section of the Genesee River is significant as the area is part of the Rochester Embayment Area of Concern (AOC). The AOC designation was given to 43 areas around the Great Lakes Basin under the U.S.- Canada Great Lakes Water Quality Agreement, signifying the chemical, physical, or biological components of the area’s ecosystem were degraded as a result of local human activities.
DEC works with regulatory partners at the USGS, U.S. Fish and Wildlife Service, and U.S. Environmental Protection Agency, as well as Monroe County Department of Health, to improve water quality and restore habitat in the Rochester Embayment AOC. The return of spawning lake sturgeon provides further evidence that restoration efforts are leading to tangible improvements to the ecosystem and support fisheries restoration and management goals. In addition, the Seneca Park Zoo and New York Sea Grant help educate the public about lake sturgeon and the Genesee River.
Dr. Dittman has worked with DEC to collect scientific data on lake sturgeon since the creation of the stocking program nearly 30 years ago. DEC stocks juvenile lake sturgeon into the Genesee River as part of a statewide recovery effort for the species, currently listed as ‘Threatened’ in New York State. Part of the recovery criteria for the species is to increase the number of spawning populations across its range in New York.
Across New York, lake sturgeon numbers are on the rise and DEC asks the angling public to continue to support their recovery by releasing accidentally hooked sturgeon immediately. The heat and stress of spawning make lake sturgeon more vulnerable to incidental mortality from angling at this time of year.
DEC depends on anglers to support sturgeon by removing the hook in accidental catches while the fish is still in the water and move to a different location or use a different angling technique once the sturgeon is hooked.

To support stewardship of lake sturgeon, New York Sea Grant has published a Lake Sturgeon Intermediate Curriculum for sixth- to eighth-grade students as part of a suite of lake sturgeon-related resources for school and public use to encourage conservation of one of the largest and longest-living native fish species, and a threatened species, in the Great Lakes.
