Upper Cascade Lake

Upper Cascade Lake is the smaller of the two Cascade Lakes. It's surface area is 26.4 acres (9.7 ha) and it has a maximum depth of 62 feet (19.2 m). The lake has low nutrient concentrations and is classified as oligotrophic. pH is circumneutral and acid neutralizing capacity is adequate, indicating that the lake has low sensitivity to acid deposition. The primary threat to Upper Cascade Lake is road runoff. The lake's surface water chloride concentration is 44.8 mg/L which is 186 times higher than normal.1 Further, in 1984 sampling by the Adirondack Lake Survey Corporation (ALSC) showed the surface water chloride concentration to be 27.5 mg/L, indicating that the concentration is increasing. 

Sampling by the Adirondack Lake Survey Corporation in 1984 found the following fish species: Round whitefish, Brown trout, Brook trout, Splake, Lake chub, Golden shiner, and White sucker. Round whitefish are a state listed endangered species and are believed to be endemic to Upper Cascade Lake. Possession of Round whitefish is illegal, as is the use of baitfish in Upper Cascade Lake. 

AsRA's Work on Upper Cascade Lake

AsRA, in partnership with the Adirondack Watershed Institute and a volunteer with the Adirondack Lake Assessment Program, samples Upper Cascade Lake on a monthly basis from May through September. We collect surface and deep water samples that are processed at AWI's lab, as well as vertical profiles of temperature, dissolved oxygen, specific conductance, and pH.
