Basin 10 - Basin Planning for the Watersheds Drained by the Black & Ottauquechee Rivers



Including: Mill, Mill, Lulls, Hubbard, Spencer and Commissary Brooks, and portions of the
Connecticut River

What's New

The new planning process for the revision of the Tactical Basin Plan has begun and will end with the release of the updated plan at the end of 2023.

This introductory StoryMap introduces you to the Basin and explains the planning process and how you can become involved.

The Vermont Department of Environmental Conservation’s (VDEC) tactical planning process is designed to identify and prioritize state and local water quality issues and implement on-the-ground watershed protection and restoration projects.

The Watershed Planning Program is charged with developing and implementing Tactical Basin Plans in collaboration with state, federal and municipal organizations, local conservation groups, interested stakeholders, and a variety of landowners and concerned citizens. Plans summarize existing water quality conditions, identify water quality issues and concerns, set priorities for surface water protection and restoration of degraded waters and guide management of the waters in the Basins.

Kick-off Meetings

Two kick-off meetings were held in May offering a presentation on the basin planning process and the current conditions of the water resources. 

Comments on the Plan are welcome and encouraged.  Please take the survey below to offer your input.

The Basin

Basin 10 consists of two major watersheds in southeastern Vermont - the Ottauquechee River watershed and the Black River watershed. Both rivers flow from the central Green Mountain range with Killington Peak in the northwest, Ludlow or Okemo Mountain in the southwest boundary and Mount Ascutney to the east along the Connecticut River. 

Basin 10 also includes about 33 miles of the mainstem of the Connecticut River and the streams that flow directly into it from White River Junction down to the mouth of the Williams River in Rockingham. [Map Description automatically generated] Among these tributaries are the two Mill Brooks that run on the north and south sides of Ascutney Mountain, Lulls, Hubbard, Spencer, and Commissary Brooks.

The Ottauquechee River has a mainstem length of 38 miles and drains an area of 223 square miles. From Killington Peak the river drops almost 3900 feet in elevation down to the Connecticut River in Hartland. 

The Black River has a mainstem length of 40 miles and drains an area of 202 square miles. It is formed at the outlet of Black Pond in the town of Plymouth and drops 3040 feet in elevation from the top of Ludlow Mountian (Okemo) to Hoyts Landing in Springfield. 

There are 32 lakes and ponds in the Basin that are 10 acres or larger covering approximately 1,877 acres. The North Springfield Reservoir, North Hartland Reservoir, Echo Lake, Lake Rescue, Lake Ninevah and Woodward Reservoir are the largest bodies of water in the Basin, each being over 100 acres in size.

Protection and restoration projects are underway and many have been identified for implementation.  This planning process hopes to identify other projects needing to be done and gain support and participation in implementing them.

Take the Survey

As we kick off the process up update the tactical basin plan for this basin the Vermont Department of Environmental Conservation (DEC) is asking for your feedback in this survey  to better understand your knowledge, concerns, and activities in relation to water quality in the Black, Ottauquechee and Connecticut River (Basin 10) both locally and watershed wide. Please fill this survey out and share with other watershed residents so we can get as broad of an understanding to guide the development of this next tactical basin plan.  This survey can take anywhere from 10 to 30 minutes based on the level of detail you provide for the questions.

Special Projects in Windsor and Woodstock!

Stormwater Master Plans are being developed for both towns and local input in needed. Please take the 

Windsor Stormwater Survey
Woodstock Stormwater Survey

Projects in the Basin can be found in the Clean Water Project Explorer an interactive application that displays clean water project information, including funding, results, and nutrient reductions from the State of Vermont's clean water tracking database. Users can search clean water project data from six state agencies and download individual project reports. 

Projects can also be found in the Watershed Projects Database, a list of all projects searchable by basin.
