Due to seasonal temperature changes, paddle sports may not be available for safety reasons. We recommend only booking 1-day in advance for any water recreation.


The Douglas County Emergency Telephone Service Authority will be testing the CodeRED emergency notification system on Wednesday, Oct. 4, at 9 a.m. The purpose of this test is to validate the telephone numbers in the Douglas County emergency notification database. There is no need for action if you receive the call.

Rueter-Hess Recreation

Reserve your Day Pass for Water Recreation/Fishing at Rueter-Hess!

Nestled in the sandstone-rimmed bluffs and Gamble Oak valleys of northeastern Douglas County, Rueter-Hess Reservoir beckons history buffs, day hikers, dog walkers, water-sport enthusiasts, and local anthropologists alike. 

Seasonal Update: For the safety of all who use Rueter-Hess, paddle sports will not be available after the overnight temperature sinks below 37 degrees. The lower temperatures will require us to winterize the rescue boat, so no one will be allowed on the water. Fishing from the shore will be allowed until ice begins to form on the reservoir.

With that in mind, we recommend booking just one day in advance and signing up for email updates.
