Kentucky Drought Condition Monitor
The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...
Videos collected for Image Velocimetry at Boneyard Creek at Urbana, IL from 2017 to 2018
The U.S. Geological Survey is testing deployments of continuous Large-Scale particle Image Velocimetry (LSPIV) streamgaging stations in areas with flashy flow regimes to measure streamflow during flood events. Videos were collected for the purpose of LSPIV streamflow analysis at a stage-discharge streamgaging station in a small, flashy urban stream in Urbana, Illinois, USA (Boneyard C

These are the notes from the April 9, 2019 Yellowstone River Compact Commission Technical Advisory Committee meeting in Sheridan, WY.
Determination of the effect of temperature (Q10) on rates of oxygen consumption in surface sediments collected from Ashumet Pond on Cape Cod, MA (2016)
This data release presents results from a laboratory study designed to measure the effect of temperature on rates of oxygen consumption within lake-bottom surface sediments at 0- to 5-cm depth. Sediment and lake water samples were collected June 8, 2016 from the South site in Ashumet Pond, Cape Cod, MA, where lake water recharges to the aquifer. Samples were shipped to Boulder, CO for l
Surface-Water Geochemistry of Mercury, Methylmercury, Nutrients, and other Constituents in Clear Lake, Lake County, California, July 2019
Clear Lake is a 180 km2 freshwater lake located in the California Coast Range, approximately 120 km northwest of Sacramento. The lake supports a wide variety of fish and bird species and is a very popular sport-fishing destination. However, fish consumption advisories associated with mercury (Hg) contamination exist for several popular recreational species. The lake is comprised of three
MODFLOW 6 and MODPATH 7 model data sets used to evaluate groundwater flow in the vicinity of Horsham and Warminster, Bucks and Montgomery Counties, Pennsylvania-Preliminary simulations for conditions in 1999, 2010, 2013, 2016, and 2017
In cooperation with the U.S. Navy, USGS developed and calibrated a numerical
MODFLOW 6 model to simulate regional groundwater flow under selected
conditions during 1999-2017 at and near the former Willow Grove Naval Air
Station Joint Reserve Base in Horsham, Montgomery County and the former Naval Air
Warfare Center Warminster in Bucks County, Pennsylvania. The model...
MODFLOW-2005 model used to evaluate water-management scenarios for the Mississippi Delta
A three-dimensional groundwater flow model (MODFLOW-2005) of the Mississippi embayment,
South-Central United States, was developed as part of a national project initiated by the U.S.
Geological Survey Groundwater Resources Program to provide updated assessments of
groundwater availability in important principal aquifers across the United States. The goals
of the...
MODFLOW-NWT groundwater flow model used to evaluate groundwater availability with five forecast scenarios in the Northern High Plains Aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming
This groundwater flow model used a previously developed three-dimensional groundwater flow model
(https://doi.org/10.3133/sir20165153) was used to assess future groundwater availability in the
Northern High Plains aquifer in Colorado, Kansas, Nebraska, South Dakota, and Wyoming. In this
groundwater flow model, a modified...
SUTRA model used to evaluate groundwater availability in central Molokai, Hawaii
A three-dimensional, variable-density solute-transport model (SUTRA) was developed
to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of
groundwater and discharge of freshwater to the nearshore environment of central
Molokaʻi, Hawaiʻi. The model was constructed using water-level and salinity data
available for the period from 1940 to
Loss on ignition near Hess Creek in interior Alaska
This data release presents measurements and derived parameters for attributes of bulk density, loss on ignition, soil-water retention, and hydraulic conductivity for a site (Richardson) near Hess Creek in interior Alaska, USA. These measurements are useful for hydrologic modeling and predictions of water availability in this region.
Soil-water retention near Hess Creek in interior Alaska
This data release presents measurements and derived parameters for attributes of bulk density, loss on ignition, soil-water retention, and hydraulic conductivity for a site (Richardson) near Hess Creek in interior Alaska, USA. These measurements are useful for hydrologic modeling and predictions of water availability in this region.
Field-saturated hydraulic conductivity near Hess Creek in interior Alaska
This data release presents measurements and derived parameters for attributes of bulk density, loss on ignition, soil-water retention, and hydraulic conductivity for a site (Richardson) near Hess Creek in interior Alaska, USA. These measurements are useful for hydrologic modeling and predictions of water availability in this region.
