Boulder Reservoir

Boulder Reservoir

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


Boulder Reservoir shoreline and basin are CLOSED for the remainder of 2020.  Fence line inside facility delineates prohibited areas. Designated trail access, storage facilities and restrooms will remain open during facility hours.

Gathering places in the managed recreation areas of the South shore, including the lawns and picnic areas are limited to groups of 10 and fewer.

No charcoal grills are allowed. No glass or dogs are allowed.  

The Dam Trail (see map below) will be closed Monday through Friday from 7 a.m. to 3:30 p.m. This is to allow for the safe operation of heavy equipment being used as part of the Reservoir Maintenance Project by Northern Water. This work is expected to occur through December 2020.
