What is a drainage basin or watershed?
A drainage basin, also known as a watershed, serves as a collection and conveyance system for rainfall and streamflow, directing water towards a central outlet like a river, lake, or ocean. This area encompasses both surface water sources such as streams, lakes, and wetlands, as well as the subsurface groundwater.
Functioning akin to a funnel, a watershed gathers both surface water and groundwater, guiding it towards a singular waterbody. Hills and ridges typically act as natural dividers between different watersheds, ensuring distinct boundaries between them.
In cases where land development necessitates mitigation measures, acquiring mitigation banking credits specific to the corresponding drainage basin becomes imperative. This ensures alignment with the regulatory framework and environmental considerations associated with the area of development.
