IRPP- Instream Flow Map Coverage

The Instream Resources Protection Program (IRPP) has established closures or flow regulation on 17 Water Resource Inventory Areas (WRIA) in Washington. This project involves the development and access to the following improved information:

• Using the 1:100,000 Hydrography data, create linear events which depict the designated and affected stream reaches in the state that have required low flow and closures,
• Providing map linkage and access to the flow information that is stored on the Internet, and
• Create a point coverage and point events that depict the flow rates at given gauges in the state and include access to the flow data for each gauge.
