Lower Yakima River Study Map
This is a map of the lower Yakima River showing locations where acoustic telemetry receivers were deployed (open circles) to detect tagged fish that were released at two sites (stars). This was part of the study titled, "Survival implications of diversion entrainment for out-migrating juvenile Chinook Salmon and steelhead.

Juvenile Sucker in Upper Klamath Lake, OR
This is a video of a juvenile sucker in Upper Klamath Lake, OR. Through decades of research, scientists at the USGS Western Fisheries Research Center have determined that over the last 30 years something has prevented young suckers from reaching adulthood. Scientists work tirelessly to find the cause of this break in recruitment into adulthood.

Eye Fluke Parasite
Fish health monitoring efforts in Upper Klamath Lake have revealed a high prevalence of warm water pathogens. The USGS Western Fisheries Research Center (WFRC) fish health team is investigating parasites as a potential threat to the vulnerable sucker populations.
