The 2018 eruption from the lower East Rift Zone of Kīlauea volcano, on the Island of Hawaiʻi, was one of the most significant and destructive events on the volcano in the past 200 years (Neal and others, 2019; Patrick and others, 2020; Anderson and others, 2023; Mulliken and others, 2024). Between May and September of that year, 24 fissures opened on the lower flank of the volcano, producing lava fountains and expansive lava flows that covered an area of 36 km2 (Neal and others, 2019; Zoeller and others, 2020). Effusion rates at the dominant vent, fissure 8, were often >100 m3 s-1, and the total eruptive volume is estimated at 0.9–1.4 km3 (Dietterich and others, 2021) making it one of the most voluminous effusive...

A three-dimensional groundwater flow model of the Central Valley in California was developed to aid water managers in understanding how water moves through the aquifer system, to predict water-supply scenarios, and to address issues related to subsidence. The USGS California Water Science Center made a detailed assessment of groundwater availability of the Central Valley aquifer system, which includes: (1) the status of groundwater resources; (2) how these resources have changed over time, particularly related to subsidence; and (3) tools to assess system responses to stresses from future human uses and climate variability and change. This effort builds on previous investigations, such as the USGS Central Valley...

These data are the results of a spatially interpolated integrated population model (SIIPM) fit to count and demographic data collected from populations of Greater Sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) located in Nevada, U.S.A. during 2013-2021. We used a novel framework, using integrated population models (IPMs), to express demographic relatedness among sampled and unsampled populations using geographic principles of spatial autocorrelation (Shepard, 1968; Tobler, 1970). Specifically, the framework pairs relatively inexpensive population count data with spatially interpolated demographic estimates. When conducted within a Bayesian framework, spatially interpolated demographic parameters...

In 2016, for the first time, an abundance of age-0 silver carp (Hypophthalmichthys molitrix) were captured at several sites upstream of Lock and Dam 19 on the Upper Mississippi River near Keokuk, Iowa. These data were collected in an attempt to determine the early life environments and frequency and timing of the reproductive events that led to a large year class of age-0 silver carp. This information is important for informing decisions about control measures. We sampled these fish to determine age (days) and early life environments using their otoliths. Sampled age-0 silver carp were collected from navigation Pools 18 and 19 from July–October 2016 using a variety of sampling gears. We aged these fish by counting...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a finite-difference numerical groundwater-flow model of the Washita River aquifer by using MODFLOW-2005 (Harbaugh, 2005) with the Newton formulation solver (MODFLOW-NWT). The 1973 Oklahoma Groundwater Law requires that the OWRB conduct hydrologic investigations of the State’s aquifers to determine the maximum annual yield (MAY) for each groundwater basin. The MAY is defined as the total amount of fresh groundwater that can be annually withdrawn while allowing a minimum 20-year life of that groundwater basin. For alluvium and terrace groundwater basins, the life requirement is satisfied if, after 20 years...
