Central Alaska Inventory And Monitoring Network Freshwater Fish Inventory And Water Quality Analysis Of Denali National Park And Preserve, Wrangell-St. Elias National Park And Preserve, And Yukon-Charley, Rivers National Preserve

This data package was created 2026-05-19 09:14:23 by NPSTORET and includes the data from a freshwater fish inventory conducted in the Central Alaska Network between 2001 and 2003. This network is comprised of Denali National Park and Preserve, Wrangell-St. Elias National Park and Preserve, and Yukon-Charley Rivers National Preserve. The purpose of this inventory was to document 90% of the expected yet undocumented species and to collect baseline data of species abundance and distribution. Angling, dip nets, electrofishing, a fyke net, gill nets, hoop traps, minnow traps, and snorkeling were all methods used in the 135 different sites that were sampled in the Central Alaska Network. Nine out of twenty one expected yet undocumented species were documented. Three previously undocumented species were documented in Denali, inconnu (Stenodus leucichthys), longnose sucker (Catostomus catostomus), and northern pike (Esox lucius). Six previously undocumented species were documented in Wrangell-St. Elias, coastrange sculpin (Cottus aleuticus), eulachon (Thaleichthys pacificus), pacific lamprey (Lampetra tridentata), slimy sculpin (Cottus cognatus), lake chub (Couesius plumbeus) and threespine stickleback (Gasterosteus aculeatus). One additional species was documented in Yukon-Charley Rivers National Preserve, coho salmon (Oncorhynchus kisutch). There were also four species detected that were not on the expected species lists, however, after urther review these four species overlap with Park units within the Network and should be included in the expected species lists. Three of these species were detected in Denali National Park/Preserve and included, Alaska blackfish (Dallia pectoralis), Arctic lamprey (Lampetra camtschatica), and humpback whitefish (Coregonus pidschian). One of these species was detected in Wrangell-St. Elias, starry flounder (Platichthys stellatus).

Report data were entered into NPSTORET by the Water Resources Division.

Data contained in CAKN_NPSTORET_BE_20260518.ACCDB (NPSTORET back-end file) were filtered to include:

The data package is organized into six data tables:

• Projects.csv - describes the purpose and background of the monitoring efforts
• Locations.csv - documents the attributes of the monitoring locations/stations
• Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping
• HUC.csv - enumerates the domain of allowed values for 8-digit and 12-digit hydrologic unit codes utilized by the Locations data table
• Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results
• Taxon.csv - enumerates the domain of taxa available in NPSTORET to identify the organism sampled for Results

Period of record for filtered data is 2001-05-30 to 2003-09-08. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at:
