General Information

The Boxelder Creek Watershed is a vast, relatively undeveloped part of northeastern Larimer County. The drainage basins in this watershed cover approximately 260 square miles and extend from extreme southeastern Wyoming into southeast Fort Collins, with flooding areas continuing past Timnath toward the southeast. The Lower Boxelder Valley is irrigated and it contains some of the best agricultural land in the County.

The Lower Boxelder Basin, close to I-25, has developed into an agribusiness and agri-research corridor which includes a major brewery, the Colorado State University Horticultural Research Center, and the Colorado State University Agricultural Research, Development, and Educational Center.

The entire Town of Wellington and a sizeable portion of the City of Fort Collins are included in the Lower Boxelder Basin. The lower, southerly portion of the Basin is more urbanized and is impacted by many existing man-made structures such as streets and buildings.
