Dona Bay Watershed Management Plan (Revised April 2007)
This watershed management plan was created to provide a strategy for protecting natural systems, ensuring good water quality, providing adequate water for human water needs, and protecting residents within the watershed’s boundaries from flooding.
The successful implementation of this plan would include the framework for restoring the biology of Dona Bay that may include water supply project(s). The link between the watershed and estuary, as well between natural system and water supply development in this CWM Plan, provides an in-depth understanding of the hydrology, how it has changed, and what effects these changes have on natural systems.
