Thompson Divide Baseline Water Quality Studies (Garfield & Pitkin Counties):  Thompson Divide Coalition commissioned these studies between 2009-2013 in order to provide valuable baseline data for water resources within the Thompson Divide. These data will serve as a “yardstick” against which future water quality changes can be compared. The major components researched: water quality and field data analysis and aquatic macroinvertebrate community conditions and tissue analysis.
