Predicting substrate size at a watershed scale to inform conservation planning for a declining salmonid species
Published: 2026-06-02

Good quality spawning habitat is critical for fish embryo development, survival, and overall population productivity. Appropriate riverbed substrate size is particularly important for riverine-spawning salmonids but the availability of suitable substrate may vary across a watershed. Predicting substrate size at watershed extents may therefore be critical to inform management and conservation of [...]
Managing Water for Birds—a Tool for the Malheur National Wildlife Refuge
Published: 2024-10-22
Subjects: Environmental Sciences, Hydrology, Natural Resources and Conservation, Physical Sciences and Mathematics, Water Resource Management
The “Water for Birds Tool” is a spreadsheet-based model (using Microsoft Excel) designed to help resource managers assess the spatial extent and types of bird habitats in the Malheur National Wildlife Refuge. The model quantifies the areas 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 [...]
Seasonally variable relationships between surface water temperature and inflow in the upper San Francisco Estuary

Water temperature and inflow are key environmental drivers in aquatic systems that are linked through a causal web of factors including climate, weather, water management, and their downstream linkages. However, we do not yet fully understand the relationship between inflow and water temperature, especially in complex managed systems such as estuaries. The San Francisco Estuary is the center of a [...]
