In February 2005, the Northeastern Watershed group jointly contributed $120,000 to hire Hubbell, Roth and Clark, Inc. and Carlisle Wortman Associates, Inc. to develop a watershed plan for St. Clair County’s Northeastern Watersheds. The watershed plan was completed September 2006. Watershed partners are mandated to submit a list of actions they will implement to address the plan’s recommendations in November 2007.
