The average depth is 10 feet (3.05 m) with the maximum depth about 18 feet (5.49 m). The water is blue
in color and quite warm in the summertime. Numerous houses and cabins line the shore, being a summertime retreat for many, and full-time residences for others. A well-known children’s summer camp, Camp Atwater, is on the north shore in North Brookfield. Lake Lashaway is part of the Chicopee River Watershed.
Lake Lashaway offers good fishing for many warm water fish. A survey[which?] conducted in 1994 showed thirteen species including Large and Small-mouth Bass, Chain Pickerel, Yellow Perch, White Perch, Black Crappie, Bluegill, Pumpkinseed, Brown and Yellow Bullhead, Golden Shiner, and Sucker. The lake was rumored to be stocked with Northern Pike in the past although no recent catches have been reported. Limited ramp parking and a large range of other species make this a better panfish lake than bass fishery compared to other lakes in the area such as Quaboag and South Ponds.
