PLM Lake Treatment


Event Details

This event finished on 16 September 2019


Lake Monterey spot treatments are scheduled annually with the complete schedule posted at the beginning of each season. The treatment schedule is weather dependent so treatment dates may change.  Treatment dates on the attached schedule are scheduled on Mondays as the “Week Of” dates. Most treatment dates start on Tuesdays. Once treatment dates are confirmed we send out alerts 24 hours in advance by text and email to all members. These alerts are also posted on our Alerts & Cancellations Page and the Member News Feed on our Members Page for all associate members, campers and guests.

We do not know what areas of the lake will be treated before PLM & Lake Management Corp. completes their assessment. On the scheduled treatment date, PLM works their way around the lake and treats areas needing attention. As they treat, they post signage containing information and what’s being treated, chemicals being used and notifying of swimming bans if necessary. Typical swimming bans last 24 hours. Please obey postings and wait until the recommended time before entering the water.

We do not always get follow up reports of exact treatment areas on the lake, so please keep an eye out for treatment signs. Signs will be posted on areas of the lake as they are treated.

For more information on lake treatments visit the PLM Lake & Land Management Website.
