The Middle St. Croix watershed encompasses approximately 19.8 square miles and is located in the east-central part of Washington County. A distinction exists between the Middle St. Croix watershed and the other watersheds of Washington County in that the Middle St. Croix watershed has many small, parallel watersheds that all flow to the St. Croix, whereas the other watersheds in the County generally have one major drainage with a headwater and outlet. Land use in the watershed is evenly distributed between agricultural uses, rural residential, and high-density residential/commercial land uses.
