NUTRIENTS, PLANKTON AND FISH IN RESERVOIRS OF THE MIDWESTERN USA ALONG A GRADIENT OF WATERSHED LAND USE

Watershed land use has large, but highly variable, effects on surface waters. Many studies have examined how watershed land use affects nutrient export and stream communities. However, little is known about how watershed land use affects lakes, especially reservoirs. We examined how nutrients, plankton and fish vary in midwestern reservoirs along a gradient of watershed land use (percent agricultural land). Concentrations of total nutrients (N and P), and phytoplankton biomass and productivity, increased with percent agriculture. However, linear or log-linear relationships between land use and most parameters were relatively weak. Many parameters showed a
