The Hoover Dam (see the Video) backs up the Colorado River and creates Lake Meade, which is approximately 115 miles long and has a surface area of approximately 225 square miles. If during flood conditions the Colorado River flows into the lake at a rate of 43800 cfs and the outflow from the dam is 6200 cfs, how many feet per 24-hr day will the lake level rise?

Answer: 0.518

Explanation: Total Area of lake = 225 sq miles = 6.273e+9 sq feet

Change in volume per second = 43800-6200 = 37600 cfs

Change in volume per day = 37600 * 3600 * 24 = 3.249e+9 cfd

Total rise of water level per day = Change in volume per day/Total lake area

= 3.249e+9/6.273E+9 = 0.518 feet/day
