About This Lake
Swimming Conditions
Harriman Reservoir's water clarity varies seasonally but generally maintains moderate visibility of 8-12 feet in optimal conditions. Summer water temperatures typically range from 68-74°F, requiring swimmers to acclimate gradually before entering. The reservoir's maximum depth exceeds 200 feet in many areas, though swimming is safest in designated access areas where depths can be monitored.

Best swimming occurs in sheltered bays and near established access points on the eastern shoreline. No lifeguards patrol the reservoir, making personal responsibility essential. Swimmers should avoid swimming alone and always wear bright colored caps for visibility. Water quality testing is performed regularly, though conditions can change rapidly. Exercise caution during windy periods when waves develop quickly across the open water.
