Abstract

In Nov 1967, a Deep Water Isotopic Current Analyzer (DWICA) was used to study current patterns in the Boulder Basin of Lake Mead to determine if low-quality water from Las Vegas Bay might enter the Southern Nevada Water Project intake on Saddle Island. Secondary objectives were to study the general current patterns in Boulder Basin and the effect of power discharges at Hoover Dam on these currents. Results of current measurements at 3 stations in Boulder Basin are given. Observations indicate a definite possibility that low-quality water from Las Vegas Bay might enter the water intake on Saddle Island. Current measurements off Promontory Point show a correlation between power discharges at Hoover Dam and current velocities in this area, with peak current velocity lagging the discharge peak by about 2 hr. Because data obtained in the study cover a short time period, suggestions for further study of general current patterns in Boulder Basin are included.
