The West Fork Cedar Watershed, located in eastern Iowa, covers approximately 112 square miles. The area is characterized by rolling hills, forests, and grasslands. Hydrologically, the watershed is part of the Cedar River basin and is primarily fed by rainfall and snowmelt. The watershed experiences significant snow accumulation during the winter months, with an average snowfall of 28 inches per year. Surface water in the watershed is primarily used for drinking water supply, and the water treatment plant removes organic and inorganic constituents, including nitrates and phosphates. Climatically, the watershed experiences an average annual temperature of 49°F and an average annual precipitation of 33 inches. Over the past few decades, the watershed has experienced changes in precipitation patterns, with more frequent heavy rain events and longer dry periods. These trends suggest potential impacts on water quality and quantity in the future.
