# Calculate Water Volume

…= surface area * Circle – Calculate radius (1/2 of the pond length); Pi x R2 or 3.14 x R x R = surface area * Triangle – Calculate the base and height; (0.5 x B) X H = surface area * Odd-shaped – Measure your pond in sections using the calculations above or use a handy online tool…
…x 7.48 = 93.5 gallons.Step 2: Calculate amount of water your basin needs to hold As a general rule you will need your basin to hold 2½ times the amount of water in your stream. To find out how much water your basin will need to hold multiply the gallons of water in your stream by 2.5. In the…
…the weight into the water and note where you feel it hit the bottom. * Repeat your measurements for at least 4 other areas within the pond doing more if the pond is particularly large. * When you have a good sampling of your pond's depth record the maximum depth and calculate the average of the…
…kits need to be capable of circulating the volume of water in the pond. If you do not know your pond size offhand you will have to determine your length width and maximum depth. Multiply L X W X (0.5 x D) to calculate the cubic feet in your pond. Water gardens are typically measured in gallons so…
…Series will fully circulate all of the water without the risk of stagnation. If you have an odd-shaped lake or one with interconnecting segments and angles consider using a system with multiple aeration plates. Now sure how to calculate your pond volume or choose the best aeration system for your…
