Windham's Water

Welcome to Windham's Water World!

Our Town is a beautiful place to visit and live and most would agree that this is due to the area’s crystal-clear streams, rivers, and lakes. Windham has over 30 significant waterbodies that provide immeasurable benefits including recreation opportunities (boating, kayaking, canoeing, swimming, fishing, ice skating), high property values, and tourism funding. Our clean waters help support wildlife, agriculture, and forestry and for many are a source of tranquility and relaxation. Use the dropdown menus below to learn about specific waterbodies, including fun facts and what is being done to protect these resources.Windham Watersheds Labeled

Pleasant River is one of Windham’s five impaired waterbodies listed by the State as having impaired water quality due to low dissolved oxygen readings and high bacteria counts. The Town is working with various stakeholders, including Cumberland County Soil and Water Conservation District, Maine Department of Environmental Protection, Presumpscot Regional Land Trust, the Town of Gray, Trout UnlimitedCasco Bay Estuary Partnership, and others to identify and address the sources of this River’s impairments.
