No person shall swim outside the designated swimming area. 

Shallow water is designated by red buoys. Swim tests will be administered by a lifeguard for permission to swim outside of shallow area.

Weather Safety

Weather at the Boulder Reservoir and along the Rocky Mountain Front Range is unpredictable and can change rapidly, becoming dangerous to boaters, swimmers and other visitors. Be aware of rapid cloud build-up, drop in temperature and sudden changes in wind direction or speed as these may signal the arrival of dangerous weather conditions.

Please be advised of the following weather safety policies:

LIGHTNING:  When lightning is seen or thunder is heard near the reservoir it will close. It is strongly recommended that people take immediate shelter in their cars. It is not safe to take shelter under a tent, tree or building, or anywhere within 100 feet of the shore when lightning is present. The reservoir will typically reopen thirty (30) minutes after the last audible thunder is heard or lightning seen.


Reservoir Caution/Bad Weather Flag (a red, triangular flag)
This flag is displayed to indicate imminent or existing weather conditions which are or may become dangerous. Swimmers are  REQUIRED  to get out of the water immediately. Boaters are strongly encouraged to get off or out of the water as quickly as possible.

Reservoir Closed Flag (a red, square flag with a black square in the middle).
This flag is displayed when severe weather or emergency conditions exist and pose a hazard to your safety or the safety of others. During this display, all boaters and swimmers are  REQUIRED  to get off or out of the water immediately.

If lightning is present when either flag is displayed, we strongly urge visitors to take shelter in their cars. When flags are removed, the reservoir is reopened.

Alcohol at the Reservoir

Patrons of legal age may possess and consume alcoholic beverages in the park. Glass containers are not allowed.

You must have proper identification available to confirm age when requested. All state and local laws apply to the consumption of alcohol and will be strictly enforced. It is illegal to operate a watercraft while under the influence of alcohol or drugs.

Lost and Found

Lost and found items will be kept at the Front gate.


The City of Boulder encourages all park visitors to help reduce landfill waste by recycling appropriate plastic, paper and metal containers in the recycling containers provided (remember: glass containers are not permitted at the reservoir).

The Boulder Reservoir is striving to become a zero-waste facility! Please help us by doing your part. Please compost food waste (including paper plates, napkins and "corn starch" cutlery). We encourage guests to bring and use special "compostable" plastic ware and discourage the use of non-recyclable Styrofoam, plastic cups and other utensils.


Groups of 10 or more require a reservation to ensure staffing levels are adequate. If a group of 10 or more arrives without a reservation, they may be asked to leave.
