Managing water for birds— A tool for the Malheur National Wildlife Refuge
The “Water for Birds Tool” is an Excel-based model designed for resource managers to assess the spatial extent and types of bird habitats in the Malheur National Wildlife Refuge. The model quantifies the area of open water, partial water, and water depths on a monthly timescale during the irrigation season (April–July) from 2021–2024. This model combines previously published datasets and incorpora

Malheur National Wildlife Refuge Watershed Synthesis: an Excel-based model for irrigation months in 2021–2024
A spreadsheet-based model (using Microsoft Excel) was developed to assess the amounts and types of habitats within the Malheur National Wildlife Refuge in southeastern Oregon, USA. The Refuge provides critical bird habitat, and the model was designed to quantify the areas of open water, partial water, and water depths during the irrigation season (April–July) from 2021–2024.

Malheur Lake is shown with turbid water and without emergent vegetation. Snowpack from Steens Mountain (shown in the distance) provides most of the inflow to Malheur Lake.
