Question

The Hoover Dam backs up the Colorado River and creates Lake Mead, which is approximately 115 miles long and has a surface area of approximately 250 square miles. If during the flood conditions the Colorado River flows into the lake at a rate of 40,000 cfs and the outflow from the dam is 7500 cfs, how many feet per 24-hour day will the lake level rise

Answer 1

Answer:

0.403ft/day

Explanation:

Area = 250 miles = 250 × 5280^2= 6.9696e9 ft

Rise per sec = (Flow in - Flow out)/Area of lake = (40,000 - 7,500)/(6.9696e9) = 4.663e-6ft/s

Therefore in 24 hours = 4.663e-6 × 3600 × 24 = 0.403ft/day
