Welcome to the Muddy Creek Comprehensive Watershed Plan (CWP) website. This website was developed to assist in the implementation of the watershed plan by providing various resources that will aid in project planning, outreach, education, and project tracking. The website is divided into six main sections (shown below), with each section housing different information and tools that will be needed for the duration of the Muddy Creek project. The official planning process has drawn to a close and now we are ready to use the tools and resources developed to implement this plan and restore the Muddy Creek Watershed!

How this website works

Read about each of the major sections of this website below. This will help guide your research and your implementation actions!


Review the background page to learn more or refresh your memory about the watershed planning process as it relates to Muddy Creek. This page goes over the TMDL framework, summarizes the approved watershed-based plan, and highlights the major issues in Muddy Creek and how to fix them.


If you want to hold a public meeting or provide general education materials about Muddy Creek to interested parties, start by going to the outreach page. Here you will find presentations, the State of the Watershed report, agency contacts, program resources, and other general watershed educational guidance.


When you’re ready to plan new projects, use the resources on this page to guide you through the grant-writing process. Resources include a spreadsheet tool that helps you estimate costs and fecal coliform reductions, a prioritization matrix to point you to problem areas, and a grant proposal template.


This page outlines all the existing activities of the Muddy Creek CWP. Here you can review the latest 319 Grant for 2011-2013 , which serves as a blueprint for the next few years of project and outreach work. Also, this page explains the role of the watershed organization within the CWP framework and specific programs that will assist you with your work.


The data clearinghouse for the Muddy Creek project houses all the relevant datasets that have been gathered, analyzed, summarized, or produced throughout the planning process. This includes all the GIS datasets, the water quality database, TMDL data, summary spreadsheets, and other useful data-driven information to supplement or help develop future analysis and evaluations.


In order to develop priorities, develop projects, and understand the data, you must map it! This custom mapping application displays many different datasets that will help you understand the spatial context of the data and how the numbers relate to issues in the Muddy Creek watershed.

About the watershed

Part of the larger Greenbrier River watershed, the Muddy Creek watershed covers 168 square miles and includes the communities of Williamsburg, Blue Sulphur Springs, and Alderson. The watershed has an average elevation of approximately 2,250 feet, and is approximately two-thirds forest and one-third pasture and grassland, with other land uses taking up less than one percent of the area. While some headwaters tributaries are steep and fast-moving, Muddy Creek itself is predominantly a meandering, slow-moving stream, only averaging 25 feet of elevation change per mile.

The watershed is heavily agricultural and there is no public sewer system. Agricultural runoff and absent or poorly functioning onsite septic systems are the primary sources of a fecal coliform impairment in Muddy Creek. Over 34% of streams in the watershed are impaired by fecal coliform. Identifying the impairment was the first step in working to correct it.
