Basin 8 - Winooski River Basin Planning

What's New

The Final 2023 Winooski Tactical Basin Plan (TBP) is ready to implement! All public comments received within the comment period were considered and addressed in the responsiveness summary included in the final plan, Appendix C. The TBP serves as the guidebook for water quality protection and restoration efforts in this watershed for the next five years. Moreover, the TBP provides the Phase III Implementation Plan update for the Lake Champlain Phosphorus Total Maximum Daily Load. A summary of the draft TBP is provided in an online StoryMap. A progress report on strategies from the 2018 Winooski TBP will be available in January 2024 as Appendix C of the Vermont Clean Water Initiative 2023 Performance Report.

Tactical Basin Planning Summary

The Winooski River watershed (Basin 8) covers approximately 1080 square miles, and accounts for 11.5 percent of Vermont’s land area. The main stem of the Winooski River flows 94 miles from Cabot to Colchester and enters Lake Champlain at an elevation 1,200 feet lower than where it originates. The watershed occupies major parts of Washington and Chittenden Counties and lesser parts of Lamoille, Orange, Caledonia, and Addison Counties. It includes fifty towns and is roughly 73% forest, 9% agriculture, 9% surface waters and wetland, 6% field and shrubland, and 3% developed area including roads.

Five-year Tactical Basin Plans provide updates on current watershed conditions and identify water quality focused strategies to protect and restore the watershed’s surface waters. The central component of the Tactical Basin Plan is an implementation table summary with targeted strategies to protect high-quality waters and to address the water quality issues in the watershed. These strategies are developed in partnership with a variety of non-profit, Conservation District, Planning Commission, town, state, and federal partners (see an incomplete list of Winooski organizations below). Stemming from such strategies, more than 1200 potential or in progress water quality projects in the Winooski watershed are searchable in the VT Watershed Projects Database and the Clean Water Project Explorer map.
