A reservoir can be a pond, lake or basin, either natural or artificial, for the storage, regulation and control of water.  Reservoirs can also include aquifers where groundwater is stored.

At AWWA we look to create reservoirs when we install our Best Management Practices (BMPs).  By doing this, we can allow more stormwater to infiltrate into the ground and be cleaned of nutrients and pollution before it enters a lake or stream.
