Klamath Suckers National Wild Fish Health Survey Case Study

The Lost River sucker, known locally as mullet, is one of the larger members of the sucker family.

Stakeholder 

United States Bureau of Reclamation 

Case Study Scenario 

The primary partner, the United States Bureau of Reclamation, along with other partners are moving Lost River Suckers, an endangered species, from Tule Lake, California on the Tule Lake National Wildlife Refuge into the Upper Klamath Lake in Oregon. 

Objective 

Identify sampling done by the National Wild Fish Health Survey on Upper Klamath Lake to aid in the risk assessment of moving Klamath suckers from Tule Lake into the Upper Klamath Lake.

Assessing the National Wild Fish Health Survey Database Web Application (URL) the search bar was used to find Tule Lake in California by typing in the search box the search term “Tule Lake National Wildlife Refuge.”  

The map zooms immediately to location.  Clicking on the map location, Lost Watershed, brings up a pop-up indicating there were 12 cases representing 1950 fish sampled and no pathogens detected in the historical data, and using the next arrow in the top banner of the pop-up window, 7 cases representing 89 fish sampled with no confirmed pathogens in the 2021-Present data.  Seeking information on the fish species sampled, user selects the related table under the historical data pop-up window to view the case list, the user selects the drop-down arrow next to the related records: title and selects species from the field list. The user can now see all the species tested. The user then uses the back arrow in the top ribbon of the pop-up to navigate back to the main pop-up screen and navigates to the 2021-present data pop-up window to select the related table. The user then uses the first drop-down list next to the related records: title and selects species from the field list to the view the species tested at the case study level and the sample level for the watershed.

Outputs 

The user exports the data in each of the related tables by selecting the Options menu and then selecting Export all to .CSV format for use in the risk assessment. 

Outcome 

The user contacts the lab (see the lab field in the table) that performed the assessments to confirm that no other clinical findings would impact the risk assessment.
