Sodium bentonite is a great option. The pond may have poor clay content or was constructed improperly. When applying the bentonite be sure to properly compact the soil using a vibratory roller for best success. Ponds with very poor soils may require a geomembrane liner in order to hold water.
Cool the water down or limit its exposure to heat by keeping it in the shade, adding ice or cooling with refrigerated pipes. This lowers the kinetic energy available to the water molecules, which slows the evaporation rate.
- By Keeping Free Water Surface Area Minimum: Reservoirs and lakes are the water bodies with large surface area. …

- By Providing Mulch on the Land Surfaces:
Oil evaporates very slowly. Oil doesn’t mix with water, and most oils are less dense than water. … When the oil is covering the water, it prevents water molecules from evaporating, just like putting a lid on a jar.
- Cover your pool. First and foremost: Use a pool cover! …
- Try a liquid solar blanket. Don’t like the idea of using a solid cover or solar blanket on your pool? …
- Turn off any water features. …
- Reduce water temperature. …
- Add windbreaks.
Liquid crystal polymers might be a class of compounds where the liquid (melt), shows no appreciable evaporation, for practical purposes.
- Add aquatic plants that will partially cover the water surface to your pond. …
- Plant tall bushes or trees around the outside of your pond to shade the water. …
- Install a trellis on the edge of the pond in a position where it will block the afternoon sunlight.
If air pressure is high on the surface of a body of water, then the water will not evaporate easily. The pressure pushing down on the water makes it difficult for water to escape into the atmosphere as vapor. Storms are often high-pressure systems that prevent evaporation.
Covering the surface of water bodies with a fixed or floating covers considerably reduces evaporation losses. These covers reflect energy inputs from the atmosphere and create a layer that prevent transfer of water vapour to the atmosphere. Fixed covers have been used for small and medium storage.
Treated areas that might become exposed and dry during water level fluctuations should be sealed with 12 to 18 inches of gravel to prevent erosion, cracking, and perforation. Ponds that seep a little may seal themselves through natural siltation.
Most leaks occur around the falls and stream, and one way to narrow your search is to shut off the pump, and see if the water level stays high. If the water level only drops when the water falls is running, you can be pretty sure the leak is limited to around the water falls or stream.
Use soil additives such as bentonite in applications of 10 to 30 pounds per square yard of surface area to create an impermeable layer. Bentonite is a colloid that expands to 10 times its size when wet and seals soil pores.
What can I expect after the bentonite pond sealer is applied? It takes about a week for the bentonite to achieve its maximum hydration state. In 3-5 days, the water level should stabilize and after that period, in some cases, it will raise.
In the case of saltwater, you may have noticed that it evaporated a bit more slowly than pure water. This is because the water molecules are attracted to the dissolved salt ions and it requires more energy to break apart those water molecules for them to evaporate.
water evaporates faster than oil. what’s happening is that it is basically easier to break apart the intermolecular forces that exist between different water molecules as opposed to different oil molecules.
Spines: Cactus spines help protect the plant from the sun, as well as guarding against animals. The spines are actually modified leaves, and contain very little water, helping to prevent evaporation.
Evaporation occurs whenever you expose wind or air to the surface of your pool. … Water molecules rise to the surface, form into a vapor and eventually get released into the air. Heated pools on cool nights experience evaporation more rapidly. This is also why heated pools lose most of their heat overnight.
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.
Pool covers minimize evaporation from both outdoor and indoor pools. Covering a pool when it is not in use is the single most effective means of reducing pool heating costs. Savings of 50%–70% are possible.
- INCREASE THE SURFACE AREA (CONTACT OF THE WATER SURFACE WITH THE AIR).
- INCREASE THE AIR MOVEMENT OVER THE SURFACE AREA OF THA WATER.
- REDUCING THE atmospheric pressure (will evaporate faster).
- In a vacum system it will evaporate easily.
Liquid water is made up of molecules of H2O attracted to one another by intermolecular forces known as ‘hydrogen bonds’. These are relatively weak, and there are always some H20 molecules whizzing around with enough energy to break free of their neighbours, even at temperatures well below 100°C.
In order to evaporate water, the considered water sample has to be heated to its boiling temperature at the given pressure, and then further heat must be supplied, which corresponds to the enthalpy of vaporization. The enthalpy of the water can by increased by any kind of heat transfer.
On average a pond will lose around 1 inch of water per week to evaporation. In larger ponds up to 3 inches per week of evaporation is normal. Dry and hot weather can increase evaporation another inch or two per week.
Average Evaporation On average a water feature will lose ½% to 1% of the gallons pumped per hour in a day.
- Floating covers (solid or modular)
- Suspended shade structures.
- Chemical monolayers.
TL;DR: When trying to make water evaporate quickly, it is best to spread the water over a large surface area and apply heat as evenly as possible. If using hot air to evaporate water, increased velocity will increase the speed of evaporation.
- Reduce the size of your pool. Probably not realistic.
- Lower the surface water temperature. …
- Reduce the air temperature and air humidity. …
- Reduce the Effect of Wind. …
- Reduce Your Pool Usage. …
- Get a Pool Cover.
Measures to reduce evaporation from reservoirs include designing deep reservoirs with minimal surface areas; concentrating storage in one central reservoir in preference to several; avoiding the creation of shallow areas; planting trees as windbreaks; preventing growth of water plants; designing the reservoir so that …
Hexadecanol or Cetyl alcohol and Octadecanol or stearyl alcohol or a mixture of these two chemicals is commonly used for suppressing evaporation from lakes and reservoirs.
- Fill the pond water up to the appropriate level.
- Unplug the pump.
- Let the pond sit for 24 hours.
- After 24 hours, check the water level. …
- Check all fittings, plumbing, and pump connections for leaks. …
- If the water has dropped, you do in fact have a leak in your pond.
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.
A leaky pond which contains water can also be sealed by pouring a slurry of bentonite, or spreading granular bentonite over the surface of the pond. This technique is usually not as successful as applying bentonite to the dry pond bottom because it is difficult to achieve an even application of the material.
