Province Lake's maximum depth is between 15 and 17 feet (4.6 and 5.2 m), quite shallow for a New Hampshire lake, so there are no coldwater fish within. It is fed by several wetland areas, one named stream (Hobbs Brook), and by underwater springs. The quality of the water is high. The lake is classified as a warmwater fishery, with observed species including smallmouth and largemouth bass, chain pickerel, and horned pout.[1] Loons, great blue heron, occasional mergansers and bald eagles are seen at the lake.
