Lake St. Clair: Impacts of Water Level Fluctuations on Wetland Fish Habitat

Scudder Mackey;
Development of regulation plan performance indicators describing water-level regime impacts on the percentage of wetland fish habitat accessible by fish during spring, summer, and fall spawning periods in Lake St. Clair. The performance indicator metric is the percent area of available (or accessible) fish habitat as a function of mean annual water level calculated from monthly means over the period of spawning activity from March to October in Lake St. Clair. Highly productive shallow coastal embayments and coastal wetlands in Lake St Clair provide spawning and nursery habitat for numerous fish species that not only populate Lake St. Clair and the connecting channels, but Lake Erie and Lakes Michigan-Huron as well. The data used to identify spawning and nursery sites are based on historical data and observations reported in Goodyear et al. (1982) and bathymetric data (NGDC (1998) augmented by additional shallow-water bathymetric data derived from NOAA navigation chart 14850_1.
