1. The annual state required inspection of the Wonder Lake Dam and Sediment Drying Facility this fall is scheduled for October 3rd, 2025.
2. The Nippersink Creek USGS stream gage at Thompson Road upstream of Wonder Lake recorded roughly 3.6 inches of rain over the past month. The gage also showed the corresponding “spikes” in streamflow from the rainfall events, as shown below in the second chart. Nippersink streamflow into the lake today is at roughly 8 cubic feet per second (cfs), which is still below the 30-year average of 20 cfs for this date.
3. The MPOA received photos of an on-going algae bloom, where the algae floating on the surface resembles spilled green latex paint. While it could not be determined if this was a “harmful” algae bloom (HAB), lake users are encouraged to use caution when those conditions are observed, with dogs particularly impacted by HAB’s.
4. The MPOA also received information regarding a lakefront parcel, where a landscaping crew was observed raking / blowing landscape waste into the lake. While it is recognized that in fall many leaves blow into the lake on their own, intentionally disposing of landscape waste in the lake unnecessarily adds to the nutrient load impacting water quality. There are currently no MPOA regulations or by-laws specifically addressing this issue, and even with the lake itself located within the Village of Wonder Lake, the Village currently does not have a landscape waste disposal ordinance. At this point, all that can be done is to discourage landscape waste being deposited in the lake, or its tributary streams.
5. As thoughts turn towards removing and preparing in-lake equipment for winter, it should be noted that one of the MPOA In-Lake Equipment Regulations requires that In-water equipment must be marked by reflective devices and Docks must display owner’s address. Addresses are an important safety feature in the event first responders have to locate an on-lake incident from the lake. It is recommended that the numbers be a minimum of three (3”) inches in height in a color that contrasts with the color of the pier.
