Can you swim in Lake Dillon?

No. Dillon Reservoir is a Denver Water drinking-water supply and full-body contact — swimming, wading, and dogs entering the water — is prohibited. Boating, sailing, paddleboarding and fishing are all allowed.

How cold is Lake Dillon?

The water stays roughly in the 40s to low 50s Fahrenheit year-round, even at the height of summer, because of the elevation and the snowmelt feeding it.

Can you rent a boat on Lake Dillon?

Yes — Dillon Marina and Frisco Bay Marina both rent watercraft during the summer season, including sailboats, pontoons, kayaks and paddleboards. Availability is seasonal and weather-dependent, so book ahead in July and August.
