Water sampling of the inlets to the lake
There were ongoing efforts to monitor the water quality entering Countryside Lake. A Water Monitoring Committee was formed.
Data was originally collected around the time of the large Toll construction across from Gilmer road in 2002-2005.
It was deemed likely that they were causing detriment to the Indian Creek inlet. CLA subsequently started a broad program of monitoring water inlets for various factors.
A lawsuit ensued with Toll Brothers, using some of this data, but was ultimately settled with the IEPA and State of Illinois.
Extensive data was collected over several years with sampling equipment, and data loggers around the area.
