Dry and hot weather can increase evaporation another inch or two per week. There are many contributing factors that play into how much water will evaporate from your pond.

Can evaporation be stopped?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.

Why would a pond dry up?
If your pond dries out annually a more permanent solution is probably required. It may be that the clay pond lining has a crack in it, or an artificial liner has a leak, or that the pond is simply too shallow and needs deepening. Specialist species will make the most of any water.
How long does it take a pond to fill up?
If you’re filling your pond using a household water tap, you’re probably looking at a max flow rate of 2.2gpm, which is about 132 gallons per hour. At this rate, running 24 hours per day, it would take 17 months to fill your pond, not allowing for evaporation, storm events, or other factors.
How do I add water to my large pond?

Why do some small bodies of water ponds do not easily dry up during summer months?
As the weather gets hotter, the density difference between warm surface waters and cold bottom waters increases to a point where two separate layers are formed. This phenomenon, called summer stratification, prevents whole lake mixing. Nutrients on bottom of the pond stay there.

Answer: Water vapour enters the atmosphere by evaporation of water surfaces such as lakes and rivers. Evaporation causes a puddle to dry up quicker if it is a warm day.

Also, it can be noted that an increase in temperature with constant humidity will contribute to an increase in the rate of evaporation since hot air can hold a greater amount of water vapour.
How do you stop evaporation in a reservoir?
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 …
