How much water evaporates from a lake each day?
If all three ingredients are present, as often occurs in the fall and winter, evaporation rates from the Great Lakes can get as high as 0.4-‐0.6 inches per day.
What is the evaporation rate on a 1 acre pond?
A seepage rate of 0.2 inch per day from a 1-acre pond does not seem significant but this rate will result in a water loss of 6 inches per month or 6 acre-feet in a year.
Does a pond loses water?
Evaporation. Causing water levels to drop roughly 1 inch per week, evaporation is the most common cause of pond water loss. But don’t panic, this is normal. Factors such as location, time of year, pond size and especially weather, can affect the rate at which evaporation occurs.
How do I stop my pond from evaporating?
Install a trellis on the edge of the pond in a position where it will block the afternoon sunlight. Afternoon sunlight during the hottest part of the day causes the most evaporation. The trellis will shade the pond during this time. To provide extra shade, plant a vine to grow up the trellis.
Is it normal for a pond to lose water?

How much does water evaporate in a day?
Depending on various environmental factors—including your location, average daily temperature, and the amount of sun your pool gets every day—your pool may lose more than half a centimeter of water every day. This translates to just under five centimeters a week, on average.
How much water will evaporate from a pool in the winter?
about a quarter-inch
An uncovered pool will lose water in the winter to evaporation in the same way it does during the summer. But the water loss is only about a quarter-inch on average during a 24-hour period when the pool is not in use. An uncovered or covered pool can have problems in the plumbing lines or pump.
Why does the water level in my pond keep dropping?
Why is my pond losing so much water?

How much water do you lose a day in a pool?
about a quarter of an inch
If pool owners or maintenance workers are constantly filling up the pool, there may be a leak. On average, swimming pools lose about a quarter of an inch of water each day, yet variations in wind intensity, humidity and sunlight can drastically change water loss rates.
Does pond water evaporate in the winter?
You’ll probably be surprised to learn, that even during the winter, running water is still exposed to evaporation. Although water loss in your pond is considerably less than during warm months, you will still need to add water to make up for this loss.
How do I stop my pond from losing water?
The only way to really remedy water loss due to evaporation is to try planting tress or bushes around the pond to get as much of the water in the shade as possible. Direct sun light will increase evaporation, especially on hot dry days. Water covering plants like water lilies can also help reduce evaporation.
Do ponds naturally lose water?
How much evaporation does my pond use?
For sheltered / shaded ponds use ½% (.005) X Gallons pumped per hour (1000) = 5 Gallons of Evaporation per day For full sun / exposed ponds use 1% (.01) X Gallons pumped per hour (1000) = 10 Gallons of Evaporation per day
How much water does a pond lose in a day?
Typically a pond in the shade will lose 0.5% of the gallons pumped per hour over the course of a day. A pond in direct sunlight will lose around 1% of the gallons pumped per hour over the course of the day. Find a number between 0.5% and 1% depending on how much of your pond is in direct sunlight throughout the day.
