Spatial stream network modeling of water temperature within the White River Basin, Mount Rainier National Park, Washington Spatial stream network modeling of water temperature within the White River Basin, Mount Rainier National Park, Washington
Water temperature is a primary control on the occurrence and distribution of fish and other ectothermic aquatic species. In the Pacific Northwest, cold-water species such as Pacific salmon (Oncorhynchus spp.) and bull trout (Salvelinus confluentus) have specific temperature requirements during different life stages that must be met to ensure the viability of their populations. Rivers...
Fiber-optic distributed temperature sensing of hydrologic processes—Diverse deployments and new applications by the U.S. Geological Survey Fiber-optic distributed temperature sensing of hydrologic processes—Diverse deployments and new applications by the U.S. Geological Survey
Fiber-optic distributed temperature sensing instruments harness the temperature-dependent properties of glass to measure temperature continuously along optical fibers by using precise pulses of laser light. In the mid-2000s, this technology was refined for environmental monitoring purposes such as snowpack-air exchange, groundwater/surface-water exchange, and lake-water stratification...
Preprint: Simulated seasonal loads of total nitrogen and total phosphorus by major source from watersheds draining to Washington waters of the Salish Sea, 2005 through 2020 Preprint: Simulated seasonal loads of total nitrogen and total phosphorus by major source from watersheds draining to Washington waters of the Salish Sea, 2005 through 2020
The U.S. Geological Survey (USGS) and the Washington State Department of Ecology (Ecology) have developed watershed models of seasonal load estimates of total nitrogen (TN) and total phosphorus (TP) discharging into the Washington waters of the Salish Sea from 2005 through 2020. The modeling approach used was dynamic SPARROW (SPAtially Referenced Regressions On Watershed attributes), a...

Assessment of groundwater-surface water exchange to support Scatter Creek, Washington baseflow
Scatter Creek, a tributary to the Chehalis River, WA, experiences summer conditions that threaten native fish populations. Each year, parts of Scatter Creek go dry. Dry stretches of stream disconnect the habitat, so that fish can’t move upstream and downstream. Some of the water flowing through streams may seep into the ground and enter aquifers, meaning that the water is lost from the stream. The...
Lake Washington Ship Canal Sustainable Rivers Project
The U.S. Geological Survey (USGS) and the U.S. Army Corps of Engineers (USACE) are refining a water quality model to better understand temperature and salinity dynamics in the Lake Washington Ship Canal. This effort is supported by the Sustainable Rivers Program, a partnership between the USACE and The Nature Conservancy (TNC).
Hydrodynamics and sedimentation in bull trout spawning habitats affected by reservoir management in the Cedar River Municipal Watershed, WA
Reservoir operations have the potential to impact bull trout spawning habitat in the Cedar River. The USGS seeks to understand potential impacts by performing bathymetric, hydrometric, and sediment surveys.
