PLM Tentative Treatment Schedule

PLM treats our lake according to a seasonal plan that is supervised by the BWLA Board. The DEQ permitting restrictions, weather and lake conditions may alter the actual date of treatments throughout the 2021 season.

Please watch your shoreline for the posting of the 8.5” by 11” yellow or green signs. These signs will indicate the date of the treatment, the products used and any restrictions on the use of treated water for swimming and recreational use. See the Sub-link titled “PLM Treatment Info” for additional information on state restrictions and lake management goals.
