During the spring and summer of 2022, the U.S. Geological Survey collected water-quality samples for nutrient analysis at 45 stations across the state of Connecticut and adjacent areas of New York and Rhode Island to better understand the groundwater discharge component of nitrogen loading to the Long Island Sound. The targeted stations were located in small drainage basins (less than 50 square kilometers) in the southern portion of the Long Island Sound watershed. Sites were selected randomly from groups based on expected drivers or controls on baseflow nitrogen loads. Factors used in the grouping included four metrics calculated for the upstream watershed: percent impervious cover, septic system density, percent...

The Murderer’s Creek mule deer herd winters south of U.S. Route 26 in river valleys near Canyon Creek, Murderer’s Creek, and the South Fork John Day River. The herd’s winter ranges are characterized by western juniper, big sagebrush, and Columbia Basin grassland communities, with medusahead and other non-native grasses invading lower elevations. In the spring, mule deer mainly migrate southeast to summer ranges distributed throughout Gilbert Ridge and the Aldrich Mountains, some traveling as far south as Devon Ridge and east to Ironside Mountain. Summer ranges in these areas contain mixed-conifer forests, ponderosa pine, and low sagebrush communities. A smaller portion of this herd migrates northeast in the spring,...

The Trout Creek mule deer herd is composed of residents and migrants that make short-range elevational migrations. Mule deer mainly winter at lower elevations surrounding Blue Mountain and the slopes of the Oregon Canyon Mountains. In spring, some of these mule deer migrate to higher elevations in the Oregon Canyon Mountains. Other members of the herd winter in the southwestern portion of the herd’s range, inhabiting areas near Hawks Mountain, the Pueblo Mountains, and the foothills of the Trout Creek Mountains. These mule deer migrate to summer ranges on the crests of Holloway Mountain and the Trout Creek Mountains. Notably, one mule deer formerly wintering on the Trout Creek Mountains migrated south from a summer...

South of Interstate 40 elk reside primarily in Arizona’s Game Management Unit (GMU) 8. Upon completing population surveys in 2021, approximately 4,000 elk were estimated to inhabit GMU 8. Their summer range is primarily characterized by high-elevation ponderosa pine forests and grasslands. The elk radiate out from various origin points within their summer range to their winter range, comprised of rims of canyons in the area, including Sycamore Canyon, Tule Canyon, and Government Canyon. This series of canyons creates an impermeable southern boundary for this herd. Their winter range along the rim country is primarily characterized by pinyon-juniper, manzanita, and scrub oak. Interstate 40 is the primary threat to...

The Hualien cluster is named for a city on the east coast of Taiwan. The region has been very seismically active at magnitudes up to low magnitude 6 in recent decades but on April 2, 2024 it experienced a 7.4 Mw earthquake. The cluster includes the mainshock of the April 2024 sequence and 15 of the larger aftershocks. Local and regional data from the very dense Taiwan network is available for events up to June 2022 but for the more recent events only a handful of the Taiwanese stations were available at the time of this analysis. Recent events all have large datasets of far-regional and teleseismic readings, however, and are well-constrained in the cluster. Only three events have magnitude less than 5.0. All events...

Summary The U. S. Geological Survey (USGS) will conduct simulations using existing aquifer data, including geologic logs from vertical profile borings (VPBs) and well installations, water levels, and pump test data available from the water districts for these production wells. Subsequently USGS will incorporate data from a groundwater pump test and additional data from new VPBs and monitoring wells. Using particle tracking maps, USGS will illustrate the spatial configuration of the capture zone and percentage of capture of the shallow and deep plumes in each production well. The model area will be limited to achieve these objectives and make maximum use of available sampling locations in the region. USGS will...

PROBLEM The valley‐fill aquifer in the lower Fall Creek valley (designated as aquifer 4, fig. 1), within the Towns of Dryden and Groton, was mapped by Miller (2000) and identified as one of 17 unconsolidated aquifers in Tompkins County that need to be studied in more detail. The east end of the valley (near the Tompkins and Cortland County border) is on the backside of a large morainal plug, which is part of the Valley Heads Moraine. A large system of springs discharge from the backside of the moraine and forms part of the headwaters to Fall Creek. The valley‐fill aquifer thins and pinches out to the west (figs. 1 and 2)— where the valley is floored by bedrock and becomes a “hanging valley” to Cayuga Lake trough....

Background and Problem Prattsville has experienced severe flooding along the Schoharie Creek, most notably during August 2011 following Hurricane Irene, which severely damaged or destroyed large areas of the town, and caused several million dollars in damages (Figure 1). Before and during a flood, forewarning and emergency response are critical. The rescue efforts of emergency responders are often hampered by lack of an understanding of where flooding is occurring at any given moment, but also where flooding is likely to occur in the near future. Emergency responders would benefit from a library of flood-inundation maps that are referenced to the stages recorded at the U.S. Geological Survey (USGS) streamgage in...

Problem The Tully Valley, located in southern Onondaga County has been the source of sediment and brackish water discharge to Onondaga Creek, a tributary to the Seneca and Oswego Rivers and eventually Lake Ontario. Information on the origin of the Tully Valley mudboils, their persistence, and the possible extent of their migration within the Tully Valley is needed to mitigate or remediate (1)the discharge of turbid water and fine-grained sediment from the mudboils, (2) land-surface subsidence caused by the removal of sediment from below the land surface, and (3) degradation of Onondaga Creek by turbidity, fine-sediment deposition, and chloride loading. Objectives To define the glacial stratigraphy and hydraulic-head...

Problem The Village of Dryden, rural homeowners, farms, and businesses in the Virgil Creek Valley tap several confined sand and gravel aquifers in the Virgil Creek valley in the town of Dryden . The valley contains a large moraine with complex stratigraphy consisting of continuous and discontinuous layers of till, lake deposits, and glaciofluvial sand and gravel. Sand and gravel units form the aquifers in the valley-fill deposits. There are at least three extensive confined aquifer units at various depths. However, little is known about (1) the location of recharge and discharge areas, (2) direction of groundwater flow, (3) extent of hydraulic connection between aquifer units, and (4) extent of surface- and ground-water...

Introduction Recent trends analysis examining the effectiveness of tidal wetland regulations and the regulatory program of the New York State Department of Environmental Conservation (NYSDEC) revealed that the regulations and regulatory program were highly effective in stemming the historic "fill and build" activities. However, the trends also revealed that tidal wetlands—specifically, low marshes—were disappearing. To help determine the cause(s) of this loss, the NYSDEC, in collaboration with Stony Brook University's School of Marine and Atmospheric Sciences (SoMAS) and the U.S. Geological Survey (USGS), established a monitoring program in 2008 that has been conducted on and in the tidal wetlands of East Creek,...

Background Climate change during the past century has resulted in changes to precipitation amounts, form (rain vs. snow), as well as frequency and intensity in the northeastern US (Huntington et al., 2009). Additional changes in precipitation are forecast for the 21st Century as the global and regional climate is expected to warm substantially (Hayhoe et al., 2007). These ongoing and projected future changes in precipitation along with other related changes to evapotranspiration rates and land use patterns will result in changes in streamflow patterns as well (Hayhoe et al., 2007). Although precipitation amounts have generally increased in the Northeast during the past 20-30 years (Huntington et al., 2009),...
