Stage-Volume-Area Table for Malheur Lake, Oregon, 2021

Malheur Lake is a vast, shallow lake in eastern Oregon. The lake is within the Malheur National Wildlife Refuge and serves as an important stop and breeding ground along the Pacific flyway for migratory ducks and geese. The bottom of the lake is fairly uniform and there are very few topographic features. A small vertical increase in lake stage may result in a large change in area or volume. The dataset includes a Microsoft Excel workbook, a comma-separated values file, a shapefile, and metadata. The Microsoft Excel workbook has two spreadsheets. The first spreadsheet contains the final stage/volume/area table for the area of interest in Malheur Lake. This first spreadsheet is also included in the data release as a comma-separated values file for users without access to Microsoft Excel. The area of interest includes Malheur Lake and not the adjacent Mud or Harney Lakes. The second spreadsheet contains calculations used to create the stage/volume/area table. The shapefile is a polygon representing the area of interested in Malheur Lake, OR. The area of interest was manually delineated to include the annually-inundated extent and the directly adjacent lake riparian areas.
