The third requirement excludes impoundments that are essentially natural lakes with small dams that increase their storage capacity only slightly. Dissolved oxygen is not used as a criterion for determininir a eoldwater reservoir, for although limiting concentrations mav occur below the thermocline in relatively rich, thermally stratified waters, the tempera- ture regime might otherwise support eoldwater game fish. Characteristics of Study Reservoirs Reservoirs differ from typical eoldwater Sierra lakes in several gen- eral features. Most apparent is age. Lake Spaulding. the oldest of the three studied, was created in 1913 (Table 1 I. Sierra Nevada lakes were mostly created by glacial action, which ended about years ago. Furthermore, most eoldwater reservoirs are considerably larger than natural lakes. Few Sierra Nevada lakes exceed 16 ha (40 acres) in surface area, whereas the majority of eoldwater reservoirs are much greater than 16 ha, and the three in this study are greater than 243 ha (600 acres)..
