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

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
