Historical drought rainfall is monthly rainfall during 2007–12 from Frazier and others (2016), whereas future drought rainfall is...
This shapefile represents the spatial distribution of mean annual groundwater recharge, in inches, for Molokaʻi, Hawaii for two water-budget scenarios. The two scenarios include: (1) historical drought rainfall and 2020 land cover, and (2) future drought rainfall and 2020 land cover. Historical drought rainfall is monthly rainfall during 1998–2002 from Frazier and others (2016), whereas future drought rainfall is monthly rainfall during 1998–2002 rainfall adjusted for a Representative Concentration Pathway 8.5 2071-99 (RCP8.5 2071–99) projection from Elison Timm and others (2015). Monthly rainfall for each scenario was disaggregated into daily values using daily rainfall during 1998–2002 from Longman and others...
These shapefiles represent the frequency characteristics of soil moisture, evapotranspiration, and climatic water deficit for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of rainfall and land-cover conditions. Four water-budget scenarios were developed to quantify the effects of drought on soil moisture, evapotranspiration, and climatic water deficit for each island as follows: (1) a reference condition, the Non-Drought scenario, consisting of rainfall conditions during 1990–97 and 2003–06 and 2020 land cover, (2) rainfall conditions representative of the driest periods during 1920–2012 and 2020 land cover, (3) rainfall conditions...

Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 40-year period (1984-2023). The Landsat BA product was consolidated into a suite of annual BA products, which in-turn were used to calculate a series of contemporary fire history metrics (30 m resolution). Fire history metrics included: (1) fire frequency (FRQ), (2) time since last burn (TSLB) and (3) year of last burn (YLB), (4) longest fire-free interval (LFFI), and (5) average fire interval length (FIL). All metrics...

The dataset includes flood-frequency data and related files for 211 streamgages operated by the U.S. Geological Survey (USGS) in Louisiana and parts of the surrounding states of Arkansas, Mississippi, and Texas as well as assembled explanatory variables (physical, climatic, and land-use characteristics of the basins). The data in this release were used in generalized least-squares (GLS ) regression analyses (Stedinger and Tasker, 1985) to generate equations used to predict annual exceedance probabilities (AEPs) at ungaged locations on streams in the study area (Ensminger and others, 2021). Flood-frequency analyses were conducted using annual peak-flow data from the 1877-2016 water years to estimate streamflows...

This data release provides a monthly irrigation water use reanalysis for the period 2000-20 for all USGS Watershed Boundary Dataset of Subwatersheds (HUC12) in the conterminous United States (CONUS). Results include reference evapotranspiration (ETo), actual evapotranspiration (ETa), irrigated areas, consumptive use, and effective precipitation for each HUC12. ETo and ETa were estimated using the operational Simplified Surface Energy Balance (SSEBop, Senay and others, 2013; Senay and others, 2020) model executed in the OpenET (Melton and others, 2021) web-based application implemented in Google Earth Engine. Results provided by OpenET/SSEBop were summarized to hydrologic response units (HRUs) in the National Hydrologic...

The two scenarios include: (1) historical drought rainfall and 2020 land cover, and (2) future drought rainfall and 2020 land cover. Historical drought rainfall is monthly rainfall during 1998–2002 from Frazier and others (2016), whereas future drought rainfall is monthly rainfall during 1998–2002 rainfall adjusted for a Representative Concentration Pathway 8.5 2071-99 (RCP8.5 2071–99) projection from Elison Timm and others (2015).

These shapefiles represent the spatial distribution of mean annual groundwater recharge, in inches, for Kauaʻi, Oʻahu, Molokaʻi, Maui, and the Island of Hawaiʻi for a set of water-budget scenarios that characterize unique combinations of drought and land-cover conditions. Two water-budget scenarios were developed to quantify the effects of severe drought and future climate conditions on groundwater recharge for each island as follows: (1) rainfall conditions representative of the driest conditions during 1920–2012 and 2020 land cover, and (2) rainfall conditions representative of the driest conditions during a future dry-climate condition and 2020 land cover. Each drought condition was combined with two hypothetical...

Historical non-drought rainfall is monthly rainfall during 1990–97 and 2003–06 from Frazier and others (2016). Historical drought rainfall is monthly rainfall during 1998–2002 and 2007–12 from Frazier and others (2016). Future non-drought rainfall is monthly rainfall during 1990–97 and 2003–06 from Frazier...
In the 1960s, US Fish and Wildlife Service (USFWS) Alaska Region Migratory Bird Management (MBM-AK) developed a protocol for aerial Trumpeter Swan (Cygnus buccinator) and Tundra Swan (C. columbianus) abundance surveys in Alaska that was used by several government agencies and private entities through 2015. This standardized survey protocol allowed data collected by these diverse organizations to be stored together in a common digital archival system called the Alaska Swan Database, which is maintained by MBM-AK. Contributions to the database ranged from relatively small, localized surveys to the statewide quinquennial Alaska Trumpeter Swan Survey. Survey timing was either the spring nesting period or late summer...

In the Gulf of Alaska, streams will experience more dramatic low water events, interspersed with larger and potentially more frequent high flow events in the coming decades. Reduced stream flows are likely to occur due to diminished snowpack and seasonal droughts, while higher flow events are likely to occur with more frequent storms and rain-on-snow events. These changes are likely to influence the growth trajectories of juvenile salmon, such as coho salmon and chinook salmon, that live up to two years in freshwater before migrating to the ocean. Stream flows can influence juvenile salmon growth by modifying food availability, water clarity, temperature, and predation risk. This high-resolution study examines...

Alaska is an ecologically, commercially, and recreationally diverse state, providing value to people and terrestrial and aquatic species alike. Presently, Alaska is experiencing climatic change faster than any other area of the United States, but across the state, comprehensive environmental monitoring is logistically difficult and expensive. For instance, only about 1% of U.S Geological Survey (USGS) stream gages are in Alaska, and only about 50% of those gages measure water temperature, an important climate change indicator. In this study, predictive models are being used to map stream temperatures under current and future climate scenarios across the Yukon and Kuskokwim River basins (YKRB) at the stream reach...

Nearshore marine ecosystems in Alaska and Hawai‘i rely heavily on organic materials and nutrients delivered by rivers and streams. It is hypothesized that the magnitude and timing of stream flows influences this delivery of materials to coastal ecosystems. However, despite previous research on the topic, there is still considerable uncertainty about how stream flow may influence these land-to-water (“ridge-to-reef") linkages, and how climate change induced shifts in runoff may ripple across ecosystem boundaries to influence estuary and nearshore marine ecosystems and species of cultural and commercial importance (e.g., Pacific salmon, gobies, and coral reefs). This project is a collaborative study to examine...

This map shows where wind projects in the coterminous U.S. are eligible to apply for a wind energy general permit or a wind energy specific permit under the USFWS Eagle Incidental Take Rule (Permits for Incidental Take of Eagles and Eagle Nests; 89 FR 9920;) and final Environmental Assessment. Wind facilities are eligible for a general permit or a specific permit based, in part, on eagle abundance information. Existing projects that are only eligible for specific permits may be determined to qualify for a general permit upon Service review of their permit application. See the Federal Register Notice and USFWS Eagle Management website for additional information about the Rule. Visit the ArcGIS Online site for a...
