Stream Monitoring

Indian Brook

The stormwater impaired portion of the Indian Brook watershed is located in Chittenden County in the Town of Essex and in the Village of Essex Junction.

The headwaters in Essex originate in the Indian Brook Reservoir and the stream flows southward beneath the major roads of Rts. 289 and 15. It enters the more developed areas of Essex Junction and then flows to Lake Champlain via Mallets Creek and Mallets Bay. The entire stream portion and its tributaries within the impaired reach are designated as cold water fish habitat pursuant to the Vermont Water Quality Standards.

Currently, the Stream Team is monitoring one site along Indian Brook with the help of volunteers. Water samples are being taken twice monthly throughout the summer and are tested for phosphorous, nitrogen, chloride, and turbidity.
