1. Lake users are reminded that with the deeper water now present in the dredged portions of the lake, ice formation on the lake can be inconsistent, particularly where streams flow into the lake. Please use caution accessing the lake unless you are positive of safe ice conditions.
1. The annual inspection of the Wonder Lake Dam and the Wonder Lake SDF was conducted by the MPOA consulting engineers on Friday, October 9th. The engineers were pleased with the concrete repair work that was done on the spillway during the Fall 2019 lake drawdown. Their summary report will be forwarded to the IDNR-OWR, as required.
1. The 2019 drawdown of Wonder Lake is now officially over. As of the beginning of December, water again began flowing over the dam spillway, allowing the sluice gates to again be fully closed. It is still expected that the lake level will still rise a bit more, as it usually maintains a normal pool from 3 to 6 inches above the spillway crest.
1. Despite the challenges posed by the heavy rains and early cold snap this fall, the MPOA contractor successfully wrapped up their repairs to the Wonder Lake dam spillway. In order to get to where the spillway leaks originated, the lake had to be temporarily drawn down roughly 5 and ½ feet. Concrete repairs were then completed on both the interior and exterior surfaces of the dam spillway where the minor leaks had been observed.
1. Believe it or not, the lake drawdown is underway. With the heavy rains experienced over the last month, Wonder Lake only returned to “normal” water level in the last few days, despite the gradual opening of the sluice gates in the dam over the past few weeks. Other than a forecast for some rain Thursday night and Friday, the 10-day weather forecast looks dry at the moment.
1. In March of 2019, the MPOA began announcing that a lake drawdown would be conducted in October of 2019. This will be the first Wonder Lake drawdown since 2007, and is being done in order to allow some needed concrete patching to be done to the Wonder Lake Dam spillway, as well as to complete some mechanical dredging in an area of West Bay that could not be accessed by the hydraulic dredge.
1. The Nippersink Watershed Association met and exceeded its fund-raising goal of $7,000, which enables the NWA to receive an additional $21,000 in grant funding from the Illinois Clean Energy Community Foundation (ICECF) for the on-going Merchant Creek restoration project.
1. An enjoyable 4th of July holiday was enjoyed by all, including the Venetian Night, parade, WLWSST Ski show, fireworks, and the complete absence of dredge pipelines and equipment on the lake.
2. Yet another reminder that the MPOA will be conducting a temporary drawdown of the lake, slated to roughly begin at the beginning of October 2019, to facilitate needed maintenance of the Wonder Lake Dam spillway. Any in-lake equipment that lake front landowners need to have moved from the lake for the winter should be completed by the beginning of October.
1. The rip-rap portion of the shoreline stabilization project at the Wonder Center – North Park, as well as around Strom and Yacht Club Islanads, is now complete. Seeding / planting of native vegetation to further help stabilize shoreline soils and protect water quality will be implemented soon. This project was largely funded by an Illinois Environmental Protection Agency grant. In order for the rip-rap to effectively protect the shoreline, it needs to stay in place, so folks visiting the islands should refrain from re-arranging the rock, or having rock tossing contests.
