The Middle Ohio Laughery Watershed (HUC 05090203) covers approximately 1,310 square miles of land in southeastern Indiana and southwestern Ohio. The watershed is primarily rural, with agriculture as the dominant land use. The hydrology of the watershed is influenced by the Ohio River, which serves as the watershed's outlet. The watershed experiences significant snow accumulation in the winter months, with an average of 20-30 inches per year. This snowpack contributes to surface water resources in the spring months, when snowmelt and runoff increase streamflow. Surface water in the watershed is primarily composed of small streams and creeks, with the Laughery Creek serving as the largest waterway. The watershed also includes several reservoirs, including the Whitewater Memorial State Park Reservoir and the Brookville Reservoir. Climatic trends in the watershed include increasing temperatures and more frequent extreme weather events, such as heavy rainfall and drought. These trends have the potential to impact water resources in the watershed, including surface water and reservoirs.
