{{#customtitle:Drainage Water Management|}}
Introduction & guidelines
The objective of a Drainage Water Management (DWM) is to control soil water table elevations and the timing of water discharges from subsurface or surface agricultural drainage systems for the following purposes:
- Improve water quality.
- Improve the soil environment for vegetative growth.
- Reduce the rate of oxidation of organic soils.
- Prevent wind erosion.
- Enable seasonal shallow flooding or surface watercourse flows for fish and wildlife habitat.
The objective of a Drainage Water Management Plan (DWMP) is to provide theproducer a framework for the implementation of DWM on existing artificially drained land. The desirability and potential benefits of a DWM system can be effectively determined by interviewing the producer, identifying field boundaries and soil types, obtaining a drain map, developing a topographic map, and then combining these components to produce a DWMP for the field or farm.
