Wet Pond

A wet pond, also known as a retention basin, is a permanent pool where stormwater is captured and held by an elevated outlet structure. The system can be designed as a multi-stage, multi-function system. For maximum benefit, at least 50% of the pond edge should be permanently vegetated with native plants to serve as a buffer, and water from the pond should be used for irrigation or some other beneficial use. Wet ponds are used to accommodate runoff and provide stability from larger design storms. They can also be used when wildlife habitats, recreational benefits, or water supply for irrigation or fire protection need to be enhanced. They should not be located within natural areas because they will not have the same range of ecological function. Wet ponds may look similar to constructed wetlands, but their plantings, soil, and subsurface systems are very different.
