Sediment and Phosphorous runoff from the Maumee River watershed, with the largest drainage of any of the great lakes watersheds, have been identified as significant contributors to water quality problems in the western basin of Lake Erie. Sediment and nutrient loading have been associated with increased harmful algal blooms and these blooms and sediment impact the most productive fishery in the Great Lakes. We use a calibrated SWAT model and climate model predictions to model the anticipated changes of discharge, sediment and phosphate from the Maumee River, both in terms of total volume and in temporal distribution of discharge. The model was calibrated to flow volume, sediment concentration and P concentrations....

A hydrologic model of the Maumee River basin in NW Ohio was constructed to determine the relative effects of different drivers (weather, tillage practices, crop planting) on sediment and nutrient flow in the river. The Maumee River watershed is the largest in the Great Lakes region, draining an area over 16,000km (super 2) . Though it only contributes a small percentage of the water into the Western Basin of Lake Erie, it contributes by far the largest volume of sediment. The area, previously known as the Great Black Swamp, was drained and clear cut for agricultural development in the 19 (super th) century. Today around 80% of the watershed is agricultural land usage. The rich organic soil contributes excessive...
