Pond Boss Forums POND CONSTRUCTION Soil questions What is considered a leak?

Bare in mind that a 5 gallon bucket used to compare evaporation will only get kinda close. The deeper sides and low surface area of the bucket will lose less water than your pond because the bucket water is "protected" from wind and much of the sun the lower the water is in the bucket. A brown feeder pan will be much closer to what the pond loses.
