Fish 513. Seminar 1. April 3.
The PRISM Context
Jeff Richey
PRISM ISSUES
* What will the coupled Puget Sound system look like over time for different spatial units?
* How can the advanced information required to address the “futures” questions be mobilized and distributed?
* How can advanced information be incorporated into and developed from education?
•How can advanced information be incorporated into the general public and ultimately policy?
WRIA-SPECIFIC TO WHOLE BASIN/ESU
Flow Verification
• Using all available flow data
• Hourly, daily, monthly, and annual flows

Evaluating the Impact of Landscape Pattern on Watershed
Hydrology
Accumulated Sum Difference (1990 – 1991) The Difference in the total amount of water flowing past the mouth of the basin between the “real” landscape (1998 classified) and the “simulated”pattern – Random, Patchy, and Smooth
Random - 1998
Patchy – 1998 more water
Smooth – 1998Less water
A 12% change in the forest composition, impacts the total accumulated flow to a greater degree then does a change in the pattern of the landscape with the same composition.
Number of sockeye salmon present in the Cedar River, Wetland 79, and Cavanaugh Pond during the 1999 spawning season (August to December). Spawners are plotted on a logarithmic scale. Data for Cavanaugh Pond was interpolated for 12/18/99.

What are the recovery actions on a WRIA-by-WRIA basis, which in the aggregate over the ESU would provide numerically definable targets for sustainable and harvestable populations of salmon at definable financial costs?
