The reservoir has a capacity of 257,304 acre-feet and is fed by the Blue River and several mountain streams. The hydrology of the reservoir is closely tied to the snowpack in the surrounding mountains, which provides the majority of the surface flow during the spring and summer months.

In addition, Dillon Reservoir is a popular destination for recreational activities such as boating, fishing, and hiking. It is surrounded by several parks and trails and offers stunning views of the Rocky Mountains.
