Album caption and index card: Typical tebeldi tree in the "qoz" sand country between An Nahud and Khuwayy (Khuwei) in central Mudirifat Kurdufan. This tree like many others in the region has been hollowed out to form a living tank for long-term storage of drinking water. Such storage is drawn upon in time of drought. Storage is replenished by lifting hand line and bucket collected surface water which accumulates around the tree during rainy seasons. Sudan. n.d. Published as figure 35 in U.S. Geological Survey Professional Paper 911. 1976.

Streamflow Permanence Probability (SPP) rasters represent the raw streamflow permanence probabilities produced by the PRObability of Streamflow PERmanence (PROSPER) model, annually for years 2004 through 2016, and overall mean and standard deviation. The PROSPER model is a GIS raster-based empirical model of probabilistic predictions of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides predictions of annual streamflow permanence probabilities at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin. Predictions...
Paleohydrologic records provide a valuable perspective on the variability of streamflow and hydroclimate that is critical for water resource planning and placing present day and future conditions into a long-term context. Until now, key insights gained from streamflow reconstructions in the other river basins across the Western U.S. have been lacking in the Milk and St. Mary River Basin. Here we utilize a new database of naturalized streamflow records for the Milk and St. Mary Rivers and an expanded network of tree-ring records from the region to reconstruct streamflow at eight gaging locations located in the mountains, foothills, and plains reaches of the basins. The network of streamflow reconstructions presented...
Streamflow and stream temperature in the Donner und Blitzen River Basin for water years 1980 through 2021 were simulated using the Precipitation-Runoff Modeling System (PRMS) with the "stream_temp" module. The model domain was discretized into 175 stream segments and calibrated to observed streamflow and stream temperature at points distributed throughout the basin. Model input files, including a PRMS control file, parameter file, and meteorological forcing files, are included in the Blitzen_PRMS_input.zip file. Select output variables for each hydrologic response unit (HRU), each stream segment, and PRMS basin summary outputs are included in the Blitzen_PRMS_output.zip file. Shapefiles of the model domain, model...
The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual predictions for 2004-2016 at a 30-m spatial resolution based on monthly or annually updated values of climatic conditions and static physiographic variables associated with the upstream basin (Raw streamflow permanence probability rasters). Predictions correspond to pixels on the channel network consistent with the medium resolution National...

The Republic of the Marshall Islands (RMI) is a nation of more than thirty low-lying atolls and islands, most of which are inhabited, dispersed across an Exclusive Economic Zone (EEZ) over 770,000 square miles in the tropical central North Pacific Ocean. Monitoring environmental conditions for potential drought risk is challenging in such a dispersed Island nation, and current drought hazard products provide generalities regarding conditions on a broad geographic scale. A team of USGS scientists and managers of natural resources and natural hazards in the RMI used IMERG (Integrated Multi-satellitE Retrievals for GPM) satellite estimates of precipitation to develop content and a template for timely monthly reporting...

Surface water quality, water isotope, and phytoplankton enumeration data were collected to evaluate the impact of an Emergency Drought Barrier (EDB) in False River in the Sacramento-San Joaquin Delta. Data were collected on six days during 2022 and 2023 (June 7, June 21, July 27, August 9, October 12, November 30, 2022, and February 21, 2023). Sampling occurred in Franks Tract, Mildred Island, the San Joaquin River, and various sloughs and cuts connecting these water bodies. High-resolution boat-based mapping data and discrete water samples were collected and analyzed for: nitrate, nitrite, ammonium, soluble reactive phosphorus (orthophosphate), total dissolved nitrogen, total dissolved phosphorus, total phosphorus,...
These raster and tabular data were compiled to develop time series data of the lower Colorado River (LCR) vegetation greenness, water use, and phenology since the year 2000. An objective of our study was to evaluate short and long-term effects of drought and biocontrol on LCR riparian and aquatic ecosystems south of Hoover Dam. These data represent spatially explicit average Enhanced Vegetation Index (EVI2) derived evapotranspiration (ET) difference, and scaled normalized difference vegetation index (NDVI*) difference maps between two decades (2000 to 2010 and 2011 to 2020) and two 5 year periods (2000 to 2005 and 2016 to 2020). The time-series period statistics data provide estimates of the riparian woodland area...
The estimation and mapping of actual evapotranspiration (ETa) is an active area of applied research in the fields of agriculture and water resources. Thermal remote sensing-based methods, using coarse resolution satellites, have been successful at estimating ETa over the conterminous United States (CONUS) and other regions of the world. In this study, we present CONUS-wide ETa from Landsat thermal imagery-using the Operational Simplified Surface Energy Balance (SSEBop) model in the Google Earth Engine (GEE) cloud computing platform. Over 150,000 Landsat satellite images were used to produce 10 years of annual ETa (2010-2019). The accuracy assessment of the SSEBop results included point-based evaluation using monthly...
Evaluating annual peak streamflows against precipitation and the Palmer Drought Severity Index can be useful in determining if trends are present in peak streamflows. This script is intended for stand-alone example operation for quick visualization of annual peak streamflow time series data with comparisons to contemporaneous monthly climatologic data. However, the script does require functions from script `vispk_example.R` that is anticipated to be a separate code example that could accompany the `breedClimate_example.R` code. Critically important is that the logic from `vispk_example.R` has been repeated at the top of `breedClimate_example.R`, so technically the former script is not needed. This code is an example...
These data are meant to support a publication "Disentangling direct and indirect effects of extreme events on coastal wetland communities" in the Journal of Animal Ecology. This dataset contains both amphibian and fish observations based on our use of plastic minnow traps. Additionally we present (specific) conductance values observed during our trapping periods.

The Rangeland Hydrologic Erosion Model (RHEM) is an online model developed by the United States Department of Agriculture that is used to predict erosion and runoff in rangelands. The model was used to determine runoff and erosion predicitions for five different scenarios in the Organ Mountains-Desert Peaks National Monument. The five scenarios that RHEM was used to look at in the monument include current conditions as of 2016; climate variability; scrub encroachment; drought, heavy grazing, or land-use pressure; and vegetation removal. The inputs for each scenario were created using an R script and compiled into separate csv files. For the purpose of this data release, the five csv files were then compiled into...

The data herein are geochemical (from X-Ray fluorescence spectrometry), grain size (percent clay, silt, sand), lithological (loss on ignition data), bathymetric, reconstructed IVT, and radioactive isotopes (14-C, 210-Pb, 226-Ra, and 137-Cs). These data were collected from sediments from Leonard Lake, Mendocino County, California, USA starting in 2014. Together, these data provide evidence for a record of extreme precipitation going back three millennia, showing regional pluvial and drought cycles.

The agro-hydrologic VegET (VegetationEvapotranspiration) model uses a water balance approach to simulate daily soil moisture (SM), actual evapotranspiration (ETa), and runoff (R). We enhanced the model to include snow accumulation and melt processes along with the separation of runoff into surface runoff and deep drainage and implemented the code using cloud technology. This publication is providing the supporting data for the updated methods and provides evaluation results for the United States and the Greater Horn of Africa.

Discrete volumetric and mid-section stream discharge measurements were conducted from July through October 2020 in H.J. Andrews Experimental Forest near Blue River, OR. The measured streams are part of the Lookout Creek basin, draining into Blue River and subsequently the McKenzie River on the west slope of the Cascade Range. ORWSC Streamflow measurements supplemented an eco-drought low-flow modeling project in partnership with the Forest and Rangeland Ecosystem Science Center (FRESC) and the USGS Water Mission Area (WMA). Measurements were collected at 25 selected sites with co-located HOBO data loggers and 7 miscellaneous (MISC) sites with no data loggers present. HOBO logger data were collected and processed...
