Fort Collins is divided into the following drainage basins. Click a basin on the map for specific information regarding that basin.

McClellands Drainage Basin

The McClellands Basin encompasses approximately 3.4 square miles in southeast Fort Collins. The storm runoff from the basin originates northeast of College Avenue and Harmony Road and drains southeast through the Oakridge, Willow Springs, Stetson Creek and Harvest Park developments. A single major drainageway, McClellands Creek, conveys flow from the upper end of the basin to the downstream discharge point along the Fossil Creek Reservoir Inlet Ditch. The majority of the basin is either developed, or is being developed, with residential and commercial land areas.

As with the Foothills, Fox Meadows, and Mail Creek basins, McClellands was developed in accordance with its original master plan and storm drainage criteria; thus many of the recommended improvements were completed. However, there are still some localized flooding problems.

The recommended plan of improvements includes pond enlargement, spillway construction, and inlet additions. Once these improvements are completed, the existing facilities would be up to current drainage standards.
