Typical Riparian

Limiting Factors/Issues Recruitment of spawning gravels Siltation of gravels High water temperature Low dissolved oxygen Nutrient loading Difficulty regulating flow Interception of groundwater/springs

Top 3 Study Needs Shasta CRMP Model the relationship of flow to rearing habitat Expand temperature/flow model and habitat/flow models to include all tributaries Expand temperature/flow model and habitat/flow models to include all tributaries Engineering and economic feasibility study for the Klamath Shasta Water Import Project

Dredger Tailings The Scott River from Callahan to French Creek was dredged for gold from the 1920s- 40s, Large- scale tailings piles remain for about 6 miles.

Snow-fed Systems 420K average annual discharge

Range of Riparian

Limiting Factors/Issues Water temperature Sediment Accessibility – canyon barriers to spawning and connectivity to summer rearing habitat Lack of flood plain connectivity Altered flow regime

Top 3 Study Needs Siskiyou RCD Feasibility study for siting of off-stream water storage of about 7-10 K acre feet. Study to determine the impact of upland consumption by over-stocked trees and junipers on stream flows. Coho habitat utilization study to determine when 1+yr. leave the tributaries for the mainstem Scott, so connectivity barriers may be addressed.

Riparian Area Riparian Area

Limiting Factors Sediment from failing roads, trails and slides TemperaturePredation Effects of fire and fire exclusion on the watershed Invasive species and toxics used for control

Top 3 Study Needs Salmon River Restoration Council Understand natural fire regime in the watershed Understand harvest and hatchery effects on key life stages of Spring Chinook Find out where Salmon River Spring Chinook go in the ocean

Summary Points Siskiyou County is a region of ecological transition and diversity on the edge of the range of salmonids Natural conditions (temperature and precipitation) can be limiting factors Localized areas of suitable habitat become very important

My Personal Top 3 Studies Locate where the fish are at their various life stages and describe preferred habitat Study the relationship of hydrology to areas of suitable habitat and its accessibility Study the relationship of hydrology to areas of suitable habitat and its accessibility Study the relationship of vegetation (upland and riparian) to altered flow regime Study the relationship of vegetation (upland and riparian) to altered flow regime
