Lake Manager’s Report – August 2025

1. The annual state required inspection of the Wonder Lake Dam and Sediment Drying Facility this fall has now been scheduled for October 2nd, 2025. 

2. The Nippersink Creek USGS stream gage at Thompson Road upstream of Wonder Lake recorded just under four inches of rain in the last 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 20 cubic feet per second (cfs), which is still below the 30-year average of 30 cfs for this date. 

Lake Manager's Report — July 2025

1. The MPOA soils committee is exploring using some of the proceeds from a pending SDF sediment sale to create a shelter at the SDF in which harvested sediment could be processed, kept dry, and available for future sales. 

2. A proposal to conduct our annual state required inspections of the dam and Sediment Drying Facility this fall has been received and approved. The proposal amount is the same as it was in 2024. The inspections are tentatively scheduled for early October 2025.

A note from our Lake Manager Randy Stowe — The moderate drought across northern Illinois continues with less than two inches of rain recorded locally in the last month at the USGS stream gage on Nippersink Creek at Thompson Road up to yesterday. The volume of Nippersink stream flow coming into Wonder Lake currently is at only 12.4 cubic feet per second (cfs), while the long-term average for this time of year is 42 cfs; roughly a 70% decrease. USGS stream gage information for precipitation, discharge and stage is available below.

Lake Manager's Report — May 2025

Lake Manager’s Report – May 14th, 2025 

1. The MPOA committee working on developing a market for the dried sediment generated by the dredging project has a potential lead. Discussions are on-going with a local landowner who has expressed in obtaining 250 cubic yards of sediment. There are also some garden centers that are interested in obtaining small quantities for evaluation of the sediment as a potential marketable item at their locations. Test gardens using the dried sediment will again be established at the Village Garden Plot.
