North Coast Watershed Assessment Program GIS Data and Synthesis

1. North Coast Watershed Assessment Program GIS Data and Synthesis Chris Keithley Fire and Resource Assessment Program California Department of Forestry Chris_Keithley@fire.ca.gov May 1, 2002 For more information on NCWAP http://www.ncwatershed.ca.gov

2. North Coast Watershed Assessment Program Goals: 1) Develop baseline information about watershed conditions to evaluate effectiveness of programs 2) Guide watershed restoration programs to ensure efficient and effective projects 3) To guide cooperative approaches to protect and improve watershed conditions through stewardship, easements, and other incentive programs 4) To implement laws requiring assessments, e.g. Forest Practices Act, Clean Water and Porter-Cologne Water Quality Acts, and Lake and Streambed Alteration Permits

3. What will our assessment program do? • NCWAP will describe current watershed conditions, processes, and uses. • NCWAP will develop hypotheses about linkages among land use activities, natural events, watershed processes and stream habitat conditions for salmon. • NCWAP will identify restoration priorities, develop general management recommendations, and provide context and guidance for cumulative effects analyses. • NCWAP will not provide specific management prescriptions.

7. Stream Flow Gages New gages: 8 total, 3 on Gualala River 2 on Big River, 2 on Albion River, and 1 on Mattole River These gauges were also equipped with water temperature sensors. For more information contact: Dept. of Water Resources John Clements, Clements@water.ca.gov

8. Assessment Methods • EMDS and its Use by NCWAP • Decision support tools. EMDS provides a method for evaluating the • relationships between environmental factors that are represented as • GIS layers for each watershed. • The stream reach component of EMDS evaluates current in-stream conditions and supports an assessment of limiting factors for salmonids. • The watershed EMDS model is applied at the planning watershed level and the sub-basin level.

9. Purpose of the EMDS Model(s) • Evaluate how watershed conditions compare with desired conditions for salmonids. • Link up with the Stream Reach Condition Model being developed by DFG that evaluates in-stream conditions. • Integrate multiple types of data. • Communicate tool.

10. Model Structure How does it work? The model consists of a series of networks that evaluate different environmental parameters. The model starts with a basic proposition: e.g., watershed or stream reach conditions are suitable for sustaining salmonid populations
