Nicatous lake is a long, narrow lake at the head of Nicatous Stream, tributary to the Passadumkeag River (see map below). It is approximately ten miles long containing 5,165 acres. For many years, there was a dam on the outlet that held a water level that was 4-5 feet higher than the current level. The high level eroded most of the soil along the present shoreline, resulting in its extremely rock appearance. There are numerous rocky points and shoals throughout the lake. The bottom is mostly sandy below the rocks and there are several sandy beaches around the lake. Mud bottom and emergent vegetation can be found in many of the coves. The water has a very brown tint caused by the many years of high water levels eroding organic material into the lake. The lake is generally shallow, and although there is some cool water near the bottom, it is very low in oxygen.

Principal fisheries: Landlocked salmon, brown trout, samllmouth bass, white perch & chain pickerel.

Brown trout are stocked each year and do provide a fishery. Salmon spawn in several of the tributaries and outlet, but are faced with heavy competition and predation from the large warm water fish population. The remnants of the old dam were removed in the late 90’s. A structure made of granite blocks was put in place to help maintain the water level and also free passage for the fish. The lake is well known for its bass, perch, and pickerel fisheries.
