Both reservoirs were generally isothermal during most of the spring, but became thermally stratified in May or June. This persisted until August or Sep- tember. Paradise Reservoir has a multiple outlet system with releases at the bottom, m, and 15 m above the bottom. Average water column temperatures are generally higher in Paradise Reservoir because colder water is released through the bottom outlet and flows into Magalia Reservoir. Oxygen levels were generally at saturation throughout the water column, but during the two study years when summer conditions were examined (1972 and 1974), levels dropped to less than 50% saturation. Occasionally levels dropped to < 1 mg/l near the bottom in mid-summer. Electrical conductivity was consistently low throughout the study period: 50-70 fimhos/cm. It increased slightly during the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original California.
