We present distributional maps and discuss native status for fish species characteristic of coldwater lakes, sampled from 203 randomly selected lakes in the northeastern USA (New England, New York, New Jersey). Eleven coldwater fish species from four families (Salmonidae, Osmeridae, Gadidae, Cottidae) were collected during the summers of 1991 to 1996 by the Environmental Monitoring and Assessment Program (EMAP). The most widespread species were brook trout and rainbow smelt, collected at 23% and 18% of the sampled lakes, respectively. Stocked (put-and-take) rainbow trout occurred at 10% of the lakes, while the remaining fish species (brown trout, landlocked Atlantic salmon, lake trout, Arctic char, lake whitefish, cisco, burbot, slimy sculpin) were collected at less than 6% of the lakes. We also provide comparative data on physical (surface area, depth, elevation), chemical (pH and total phosphorus), and watershed characteristics of the lakes where these species were collected.
