There are a multitude of considerations to keep in mind when designing and installing a pond. Existing structures, trees, landscaping, and utilities need to be taken into consideration on the pond site and the surrounding area. The area should be assessed with a laser level to determine the high and low areas in relation to the viewing areas. Rainfall, snowmelt, watershed, and winter temperatures need to be taken into consideration. Soil will need to be assessed because clay, rock, bedrock, and sandy soil can all affect the structure of the pond. Supplementary soil may need to be brought in to create the right slopes. When constructing the pond itself, ledges and terraces must be built to avoid dangerous drop-offs, the correct filters and piping will need to be installed, and the dirt must be dug to ensure the proper depth for your needs. Failing to take these considerations into account can result in costly problems later on.
