Plan Your Visit
These past months, we’ve been working hard to interpret state and local guidance to ensure that recreational facility operations align fully with efforts to protect public health.
The following guidelines are in place to allow the Boulder Reservoir to be open for passive recreation, permitted boating/watercraft use and fitness swimming (by reservation) only:
- All rafts and non essential docks remain CLOSED to maintain social distancing requirements and to eliminate any potential group gatherings.
- Swimming is only allowed for ages 16 and up with reservations for fitness swimming.
- The facility is currently open for a limited capacity of non-boating passive recreational visitors (walking, running).
- No groups of larger than 10 individuals,are allowed to gather, including boating with anyone that does not reside in your household.
- Always bring a face covering when visiting the reservoir. If you are more than 12 years old, you must wear a face covering anytime you cannot maintain 6 feet of physical distance with those outside of your household or when interacting with staff. Boulder County Health Order
- Please see additional information about Boats/Watercraft or Swimming Area in the respective tabs below on how to access these opportunities.
Thank you for respecting each other and staff while enjoying your visit to Boulder Reservoir. We appreciate your patience as we all adapt to new operational policies and procedures.
The reservoir will remain open only if everyone abides by these protocols and the safety and physical distancing requirements. We will continue to evaluate the situation daily and make changes and adjustments as needed; hours, protocols and services are subject to change.
Boating and fitness swimming are being allowed to resume as part of the city’s transition from response to recovery mode. The restoration of additional Parks and Recreation services, including those at the reservoir, also will occur in phases with a flexible timeline.

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.
WEATHER WARNING FLAGS:
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.

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.
