Throughout 2011, work began to re-evaluate the options for controlling the growth of the invasive, non-native aquatic plants in Bangs Lake, specifically Eurasian Water Milfoil and Curlyleaf Pondweed. These 2 species dominate the lake and if left to grow unchecked, these plants would not only limit recreational activities, but also crowd out the native, high-quality plant species that are vital to the health of the lake. Some options for controlling their growth include continued mechanical harvesting, the use of aquatic herbicides, and/or the use of biological controls such as various beetle species. The Village is required to consult with the Illinois Department of Natural Resources (IDNR) on any changes to the current plant control program. In order to complete this consultation, the Village is required to develop a comprehensive lake management plan that IDNR will review. These reviews average 7 months. As such, it is expected that this project will be completed by summer 2014.
In September 2011, the Village worked with the Bangs Lake Advisory Committee on revising the written standard operating procedure related to managing the water level in Bangs Lake. Bangs Lake drains through an outlet located on its southwest side. The outlet contains a concrete structure in which flow control bars can be placed to hold back water in the lake. The procedure describes how to measure the water level in the lake, and when the flow control bars should be installed and removed. The Village and the Bangs Lake Advisory Committee agreed to leave the bars in at the end of the summer season for 1 additional month. This change benefits boat owners who some-times struggle with removing their boats due to low water levels in the lake.
