Rainbow Lake, body of water
Rainbow Lake is an artificial reservoir in Rainbow Township, Piscataquis County, Maine, covering about 1,600 acres with an irregular shoreline featuring numerous coves and inlets. The lake reaches depths of up to 130 feet (40 meters) and maintains good water quality while supporting coldwater fish species in its clean waters.
The lake was created as a reservoir to manage water flow and supply for surrounding communities. Over time it became a valued recreational destination while maintaining its primary role in water management for the region.
A boat launch provides access for small boats and canoes, while the undeveloped shoreline offers quiet spots for paddling and swimming. The natural surroundings and absence of nearby towns make it an accessible destination for outdoor activities throughout the year.
The lake remains free from invasive aquatic plants and is monitored by local authorities to preserve its ecosystem. This careful management keeps it a clean fishing destination without the ecological problems that plague many artificial reservoirs elsewhere.
