Abstract From April 1969 to October 1974 field and laboratory analyses and observations were made at approximately weekly intervals to evaluate the relationship between the quality of water impounded at Indian Creek Reservoir (ICR) and the reclaimed water exported by the South Tahoe Public Utility District. The reclaimed water comprised from 70 to 80% of the annual impoundment. On the average the reclaimed water contained 0.1 to 0.2 mg/l of phosphorus and 15-24 mg/l of ammonia, the latter making it toxic to fish implanted in ICR. However, as the reservoir matured, nitrification-denitrification removed most of the nitrogen from the system and by March 1970 the reservoir had become an excellent trout fishery. Excess N in comparison with P evidently precluded blooms of blue green algae but low phosphorus did not prevent the impoundment from becoming typical of a highly productive environment, with vascular plants invading to considerable depths because of the high degree of clarity of the reclaimed water. It is concluded that the reservoir responds to more complex factors than are measurable by analysis of reclaimed water.
