How to Calculate Acre-Feet of Water
Essential Tools for Calculation
Accurately calculating acre-feet of water requires specific tools. Essential tools include a calculator, measuring tape, pencil, paper, and a surveyor's wheel. These tools help in measuring the physical dimensions of the water body and performing calculations.
Understanding the Calculation Formula
The formula to calculate acre-feet of water is V = (L * W * D) / 43560. Here, V represents the volume of water in acre-feet, L is the length in feet, W is the width in feet, and D is the depth in feet. This calculation helps in determining the total volume of water in a specific area, converting it to acre-feet by dividing the result by 43,560, the number of square feet in an acre.
Practical Examples and Conversion
Understanding real-world applications of acre-feet can clarify this measurement's scale. For instance, 1 acre-foot per year equals 119 cubic feet per day and 3.38 cubic meters per day. Higher volumes like 1 million acre-feet equal approximately 1.233 cubic kilometers. Recognizing these examples can aid in grasping the magnitude and importance of accurately calculating acre-feet for projects involving water management and storage.
How to Calculate Acre-Feet of Water
Acre-feet is a common unit used to measure the volume of water in large water resources such as irrigation channels, reservoirs, and lakes. It represents the water volume needed to cover one acre of surface area to a depth of one foot. Here, learn the precise steps to calculate acre-feet of water.
Understanding the Basics
An acre-foot is the volume of water required to cover an area of one acre with a foot of water depth. It equals roughly 325,851 gallons. This measurement is vital for managing large-scale water resources.
Steps to Calculate Acre-Feet
To find the volume in acre-feet, use the formula V = L * W * D / 43560, where:
Start by multiplying the length, width, and depth of the water area in feet. Then, divide the product by 43,560 (the number of square feet in an acre) to convert your final result into acre-feet.

Calculating Acre-Feet of Water: Practical Examples
Example 1: Rectangular Reservoir
To calculate the acre-feet of water in a rectangular reservoir measuring 400 feet in length, 200 feet in width, and 10 feet in depth, use the formula: (Length × Width × Depth) / 43560. Therefore, (400 ft × 200 ft × 10 ft) / 43560 = 183.67 acre-feet.
Example 2: Circular Pond
For a circular pond with a radius of 30 feet and an average depth of 12 feet, the acre-feet is calculated by (π × Radius² × Depth) / 43560. Here, (3.14159 × 30² × 12) / 43560 ≈ 29.34 acre-feet.
Example 3: Irregularly Shaped Lake
If an irregularly shaped lake has been surveyed to have an estimated surface area of 2 acres and an average depth of 15 feet, the acre-feet is direct: (Surface Area × Average Depth) = 2 ac × 15 ft = 30 acre-feet.
Example 4: Stream Flow over Time
To determine the acre-feet of water that flows through a section of a stream in one day, if the rate of flow is 500 cubic feet per minute, calculate (500 ft³/min × 1440 min) / 43560. This equates to (720,000 ft³) / 43560 = 16.53 acre-feet per day.
Example 5: Rainfall Runoff
When calculating water accumulation from rainfall, suppose your field of 3 acres receives 4 inches of rain. Convert inches to feet and use (Acres × Rainfall (ft)) = 3 ac × (4/12) ft = 1 acre-foot.
