Science Datasets

The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

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....
