Boulder Reservoir

Boulder Reservoir

"Perhaps the truth depends on a walk around the lake." 
-Wallace Stevens

Demand for small watercraft permits is extremely high. This year we offered our typical 1200 season small craft permits and new for 2021 we added 500 weekday only permits to provide additional opportunities for small craft users. Despite these additionas we sold out of ALL small watercraft permits the first week of April. We will not be offering any additional permits for 2021. We will be collecting data during this season and using that data and feedback to evaluate during our end of year review process which takes place in October. At this time, we will evaluate the sales process as well as permit numbers and feasibility for operational adjustments for the 2022 year.
