City of Wentzville, Missouri

2012-2013

The City of Wentzville, Missouri, was awarded a grant for the Dry Branch Watershed Clear Stormwater & Green Parks project from the Missouri Department of Natural Resources and the United States Environmental Protection Agency, under the provisions of Section 319(h) of the Clean Water Act. Under this grant, Water Resources Solutions prepared a watershed management plan for the Dry Branch Watershed. The watershed management plan follows EPA’s Handbook for Developing Watershed Plans to Restore and Protect Our Waters and includes the nine minimum elements of watershed plans.

The watershed management plan included the following activities:

• Identify sources of nonpoint source pollution sources within the Dry Branch Watershed.

• Identify and quantify potential nonpoint source pollution mitigation measures.

• Develop a set of evaluation criteria to judge the effectiveness of the installed mitigation measures.

• Inform and educate stakeholders and residents within the Watershed.

The purpose of the Watershed Plan was to characterize the condition, develop plan and policy within the watershed regarding water quality, and identify future water quality projects within the watershed. 

The Dry Branch Watershed is located in northwestern St. Charles County, Missouri, near the center of Wentzville. It is a sub-watershed of the McCoy Creek Watershed and Big Creek Basin.  It covers approximately 6,800 acres consisting primarily of residential, agricultural and commercial property.
