Protecting our Rivers

Yurok Tribal Projects

Current projects supported and funded by Klamath River Inter-Tribal Fish and Water Commission dollars received from N.O.A.A. (National Oceanic and Atmospheric Administration) through the PCSRF (Pacific Coastal Salmon Recovery Fund) project to the following Tribes along the Klamath River for project year 2012.

Yurok Tribal Projects

  • Fish Disease Dynamics in the Klamath River

This project involves researching an monitoring that involves a suite of potential tasks to help evaluate fish disease dynamics in the Klamath River Basin for juvenile and adult salmonids.  Potential tasks that will be accomplished include the following: monitoring myxozoan parasite levels in the Klamath River mainstem, dtermination of polychaete population density and myxozoan infection levels, monitoring of adult Chinook salmon health and Ich infection levels, an other tasks as determined by collaborative partners including USFWS, Oregon State University and PacifiCorp.

  • Juvenile Salmonid Ecology and Survival

This project involves research and monitoring of juvenile salmonid ecology and survival dynamics in the mainstem Klamath River.  Potential tasks that will be accomplished include the following: diet composition of juvenile salmonids; macro-invertebrate abundance, composition, and distribution; PIT tagging of juvenile salmonid to determine their movements and survival; bio telemetry tagging of juvenile salmonids to determine their movement, habitat use, and survival; and other relevant tasks as needed.

  • Klamath Basin, Shasta and Scott River Collaborative Management

These funds will be used to participate in technical studies of flow management in the Shasta and Scott River basins.  This includes participation in management activities as well as the acquisition of technical expertise for review and implementation of water management studies.

  • Tributary Confluence Fish Passage Restoration and Enhancement

Recent research in the Klamath Basin, indicates that both summer and winter refugia associated with the lower reaches of Klamath tributaries are critical for the survival of juvenile salmonids, and in particular, juvenile Coho.  Fisheries surveys have identified consistently high numbers of juvenile salmonids in habitats that function both as summer and winter refugia.  Fish passage barriers include aggraded stream mouths where streams will either run sub-surface or become too shallow for fish to navigate because of large alluvial deltas.  This problem has been exacerbated by past upslope disturbances such as wildfires, road failures and mining that have increase3d the sediment load particularly at the mouths of these tributaries.  Many channels and stream mouths have been severly altered during past flooding (1955, 1964, 1997 and 2006), as described in the 1998 report titled, The Flood of 1997, by the Klamath National Forest, which links flood damaged stream channels to impacts from wildfire and road crossings.  Chronic low flows in the mainstem Klamath and Scott have increased the impact of seasonal barriers at the mouths of tributaries.

  • Yurok Tribal Lower Klamath Tributary Outmigrant Monitoring

This project is a continuation of long-term monitoring activities within Blue Creek, the largest anadromous fish-bearing streams of the Lower Klamath River (Weitchpec to the ocean) that is located within the Yurok Indian Reservation.  YTFP initiated annual outmigrant trapping projects in Lower Blue Creek in 1995.
