Both retention and detention ponds are designed to help control the runoff and limit flooding during high water times. Main basins can be designed to achieve a variety of water quality retention goals. The amount of water that a retention pond can store is determined by its storage capacity and infiltration rate. Retention ponds can be built in a variety of shapes and sizes depending on the landscape. Depending on the quantity and distribution of vegetation, they can help to create cool islands in metropolitan areas (as a result of evapotranspiration, water supply, shading). to a pond or wetland that has such a small contributing drainage area that little

As mentioned earlier, retention ponds can be low-oxygen environments that are not conducive to the survival of fish and other aquatic life. Existing natural water bodies are not suitable as retention ponds. A detention/retention pond is a basin that is designed to catch runoff water from higher elevation areas which are used to prevent or minimize flooding during high water periods. This can be done by regularly removing any excess plant growth, adding additional aeration devices to improve circulation and oxygen levels, and removing any dead animals that may have accumulated around the pond. of all deep pool areas (four feet or greater in depth) should be surrounded

Alabama Department of Environmental Management During heavy rains, there may be an excess of runoff entering these ponds, causing them to overflow and release water more quickly than usual. The purpose of this zone is to allow for additional filtration processes so that the water quality entering surrounding areas remains high. The spillway is a controlled release path that is used to manage the flow of stormwater runoff downstream during major rainstorms. Many of those smaller ponds are on private property.

Stormwater is a major concern because if not properly handled, it can lead to flooding, erosion, and pollution of neighboring water bodies. You can also remove dead animals or plants on a regular basis if they begin to accumulate around the area. Retention ponds cannot be constructed in wetlands because the water table is generally already too close to the surface. This is critical during heavy rain events when stormwater runoff increases dramatically, causing waterways to overflow and potentially damaging surrounding areas. The design must include measures that will allow for safe channeling of flows over the ponds design event, with the consequences of any pond embankment failure taken into account. Additionally, the formatting and pagination of the posted documents varies from the formatting and pagination of the official copy. A pond is a type of stormwater management facility designed to collect rainwater and pollutants and prevent downstream flooding. Any person who violates this section shall be guilty of a misdemeanor, and upon conviction thereof shall be punished by a fine not to exceed $500. Retention ponds can be used in agricultural settings to collect runoff from poor permeability surfaces (such as tracks and farmyards) or as part of the agricultural landscape. The soil beneath the pond should be sufficiently impermeable to prevent it from drying out. It is also important to consider the location of the outfall and to design so that it is clear of structures, trees, or other obstacles.
