Mishawaka Fish Ladder

Mishawaka Fish Ladder. . , St. Joseph River Trout and Salmon Project , , The Mishawaka Fish ladder is an integral part of the St. Joseph River Trout and Salmon Project. This Project was conceived in the 1970's by the Indiana and Michigan Departments of Natural Resources in consultation with the US Fish and Wildlife Service. Project infrastructure consists of a trout and salmon hatchery and five fish passage facilities. These fish ladders enable migratory fish to move freely throughout the lower 63 miles of river, from Lake Michigan upstream to the base of the Twin Branch AEP hydroelectric generation dam and facilities. The Richard Clay Bodine State Fish Hatchery is located on the east side of Mishawaka. The four other ladders are in South Bend, Indiana and in the Michigan cities of Niles, Buchanan, and Berrien Springs. The goal of the Project authors was to extend into Indiana an already established and very successful trout and salmon fishery in the Michigan waters of the St. Joseph River. Furthermore, the Hatchery and its associated fish ladders meet the Indiana Department of Natural Resources’ mission to professionally manage Indiana’s fish and wildlife for present and future generations, balancing ecological, recreational, and economic benefits. , , Hatchery Fish Culture , , Skamania Steelhead , The Skamania strain steelhead trout comes from the Pacific Northwest. This summer-run variety of steelhead was first introduced by Indiana to Lake Michigan in 1975. For five years, eggs were imported from the Skamania State Fish Hatchery in Washougal, Washington. Indiana then initiated its own broodstock collection program. These fish typically begin their spawning migration in June, about four months earlier than their winter-run counterpart. Peak migration occurs in September. Both summer-run and winter-run steelhead spawn late winter/early spring before returning to Lake Michigan. Other characteristics which set Skamania apart from their winter-run cousin are their long slender body and acrobatic antics when hooked. These qualities make the Skamania a very sought after prize by anglers. , , Little Manistee Steelhead , Steelhead were first introduced to Lake Michigan in the late 1800's and originated from California and Oregon. After decades of releasing hatchery reared fish, some steelhead populations became naturalized in many streams and rivers. The Little Manistee River has one of these naturally reproducing populations and is the source of eggs for Indiana. This winter-run strain of steelhead will begin their spawning migration as early as October. Peak migration will be late winter. Spawning will be late winter/early spring at the same time as the Skamania. , , Coho Salmon , The first successful stocking of Coho into a Great Lakes tributary was in 1966. They were released into the Platte River south of Traverse City, Michigan. Also native to the Pacific Northwest, Coho were introduced in hopes to control an overpopulation of prey fish in Lake Michigan known as alewife. The experiment worked and led to the modern day Great Lakes trout and salmon programs enjoyed by all Great Lakes states and Ontario. Indiana obtains their Coho as eggs from the Platte River. Their spawning migration begins in September with peak migration in October. Spawning will occur in October and November. , , About the Hatchery and Fish Ladders , , In 1981, a 40-year lease agreement was signed by the American Electric Power Company and the Indiana DNR for a 10.9-acre land track to serve as a hatchery site. The Richard Clay Bodine State Fish Hatchery was completed in 1983. The hatchery’s primary responsibility is for the release of Coho salmon and two strains of steelhead trout into the St. Joseph River. The hatchery’s most notable steelhead strain is the Skamania. The other variety of steelhead is more commonly referred to as the Little Manistee or Michigan strain. , , This Fish Ladder located at the historic Mishawaka overflow Dam was constructed in 1991. Fish ladders are typically installed adjacent to dams to allow migratory patterns to exist where obstacles such as dams may otherwise prevent it. The Mishawaka Fish Ladder provides slotted chambers of concrete and steel that gradually rise from the water level below the dam to the water level above it. Using the fish ladder, a fish will “climb” up and over the dam to the river above. Since many fish species return to the streams they were born in to spawn, this fish ladder is necessary for the natural propagation of many species. The appearance of the ladder was updated in partnership with the City of Mishawaka in 2013.
