Water in lakes can be measured with acre-feet.

Exclusive acre-foot represents the quantity of water it would require to cover any acre of land 12 inches deep. The term is frequently employed in irrigation and water resource management to allot water resources and to figure out the volume of water from reservoirs plus other bodies of water. Because acre-feet are measures of amount, you will need to know the surface location plus the regular depth about any physique of drinking water to calculate the number of acre-feet it contains.

Difficulty: Moderately Easy

Instructions

Things You'll Want

1 Determine the area area about the reservoir. If the reservoir is roughly oblong, measure the length also the width in feet. Multiply the period times the width to find the surface location in rectangular feet. For circular bodies about water, work out the surface region in feet by way of the formula "radius x radius x 3.14." If you only know the circumference (range around the edge) regarding the water physique, you can find the radius by dividing the circumference in 6.18.

2 Find the average depth of the body of drinking water. Take measurements from feet uniformly throughout the water body, and average the results to get the normal depth.

3 Multiply the surface region by the average depth to find the number about cubic feet in the reservoir.

4 Divide the number of cubic feet with the reservoir via the quantity of cubic feet within an acre-foot (43,560) to find the amount of acre-feet from the reservoir. For example, if the reservoir includes 100,000 cubic feet of drinking water, divide 100,000 from 43,560 to get hold of the result about 2.3 acre-feet.

Tips & Warnings

One acre-foot equals 43,560 cubic feet, 325,851 gallons, 1,233,482 liters or 1,233 cubic meters.
