Klickitat River BasinWatershed Management PlanqqqqqqAssessment of conditions limiting natural fish production: Little numeric informationhas been documented regarding the quality of fish habitat in the watershed. Collection ofdata to characterize habitat conditions in the watershed and identify the limiting habitatcharacteristics (see Section 7 for further discussion and definition) is needed. Thisinformation will be used to identify priority actions for habitat restoration andpreservation.Fish Passage through Culverts: Culvert inventories need to be updated in somelocations to identify areas of passage concern and estimate the benefit of replacement ofthese structures to fish population production.Fish Passage into Little Klickitat Subbasin: There is little known about how often (orif) the waterfall at river mile 6.1 is passable for steelhead or other migratory fish species.An in-depth study of passage at the falls is recommended to determine the frequency(number of years) at which this falls is passable and the numbers of fish that are able topass in years when flows are high enough to support passage.Fish Population Abundance and Distribution: At present, information regarding fishabundance is limited. Data on total size of native anadromous populations, includingthose listed under the Endangered Species Act, are not available. Monitoring of fishpopulations to provide estimates of the number of fish returning to the watershed andchanges in those numbers over time is needed.Carrying Capacity: The carrying capacity of the Klickitat basin for salmonid species isunknown.Species Interactions : Interactions between and risks posed by hatchery/introducedsalmonid stocks and native naturally spawning fish populations have not been assessed.Identified Data Gaps 33 May 3, 2005
