Drought
Drought
USGS has a long and proven history delivering science and tools to help decision makers manage and mitigate the effects of drought, and we continue to improve data collection during and after drought events to gather critical, ephemeral information; synthesize datasets and models to better understand drought drivers, responses, and interactions; and deliver effective information to address drought through partnerships with stakeholders, policymakers, and the public.

Osoyoos Ice Jam
The Issue: Ice jams can occur at the outlet of Osoyoos Lake on the border of Canada and the United States, resulting in a decrease or complete interruption in streamflow on the Okanogan River. These ice jams appear to be occurring at a greater frequency than they have in the past and interruptions in streamflow can hinder the passage of anadromous fish and impact downstream water rights and water...
Updated classifications of flow permanence on streams in the Colville National Forest
The Issue: Streamflow permanence refers to the probability that a stream will lose surface flow (become a dry channel), as well as the timing, duration, and frequency of drying. Patterns of streamflow permanence drive important decisions regarding forest management and other land uses. The Colville National Forest Land and Resource Management Plan (2019), for example, specifies riparian management...
Analysis of USGS Surface Water Monitoring Networks
The issue: National interests in water information are important but challenging to incorporate into planning and operation of a monitoring network driven by local information needs. These interests include an understanding of the spatial variability in water availability across the United States, anthro-physical factors including climate and land use that affect water availability, and federal...
Drought preparedness in Mt. Rainier National Park
The Issue: Water supply for park operations and backcountry users is determined by the spatial extent of perennial streams in Mount Rainier National Park (MORA). In addition, the presence or absence of streamflow (flow permanence) is related to water temperature, which influences the occurrence and distribution of aquatic species including cold-water fishes and insects. Information about the...
Assess the utility of a regional aquifer system groundwater model to inform the USGS National Hydrologic Model
The Issue: In Washington State, groundwater (GW) inflow to streams, or baseflow, is essential for maintaining aquatic habitats, and for out-of-stream uses such as irrigated agriculture during the typically dry summers. However, the National Hydrologic Model (NHM) currently is most suited to predicting total daily streamflow. This project aims to assess the NHM’s performance in simulating baseflow...
Water use
The Issue: Comprehensive water-use data and analysis of water-use information are needed to quantify the stress on existing supplies and to better model and evaluate possible water-supply management options to supplement traditional water-supply approaches. Advances have been made in the ability to control, divert, and develop water, but little attention has been paid to keeping accurate accounts...
NWIFC Water Assessment
Water resources are essential to Native American Tribes in western Washington for instream and out-of-stream uses. As the demand for water across the region increases, western Washington Tribes need critical information about water availability, water use, and ecological needs for water in order to manage their resources. To assess tribal water resources comprehensively in western Washington, the...
