Report: Eva May Because the Eva May is well described in the literature (Knopf, 1913; Pardee and Schrader, 1933; Roby and others, 1960; Becraft and others, 1963) and it is on private land with no affected forest service land for miles downstream, it was not examined in detail as part of this project. No discharges exist, and the large tailings pile in the floodplain of Cataract Creek has been mostly removed for reprocessing. Sampling in Cataract Creek downstream revealed.... The mine lies at the east end of the Crystal vein and produced over $2 million dollars in metals before 1910. It was one of the largest producers in the Basin district.
