MASTER DRAINAGE PLAn
The Bullhead Gulch watershed is approximately 13 square miles and is located in Boulder County, the City of Lafayette, the City of Louisville, and the City of Erie. The watershed contains residential development, commercial development, and agricultural land/open space. It is comprised of two distinct sub-basins: Bullhead Gulch, and its tributary, Prince Tributary. Prince Tributary flows into Bullhead Gulch in the lower part of the watershed, and Bullhead Gulch flows into Boulder Creek.
