"Crater Lake, Oregon, has no surface outlet and loses its inflow by evaporation and leakage. In order to understand the hydrology of the lake and the leakage of the lake in relation to near by cold springs, water samples were collected for chemical and isotopic analysis. No spring analyzed had evidence of more than 10 percent Crater Lake water. Chemical and isotopic analysis show that Crater Lake is well mixed. Crater Lake also has anomalously high chloride, boron, lithium, sulfate, and silica concentrations compared to near by Diamond Lake and to cold springs discharging on the flanks of Mount Mazama. This elevated chloride may be caused by input of thermal water. Weight ratios of Cl/Li are within the range of western United States hot springs and significantly below those for surrounding cold springs waters. Estimates of total heat flow out of the lake bottom range from 670 to 1380 mW/m2, also suggesting addition of thermal water to the lake bottom."
