Data

The Stochastic Empirical Loading and Dilution Model (SELDM) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation...

The Coastal Change Hazards Technical Capabilities and Applications project at the U.S. Geological Survey (USGS) exists to understand and predict storm impacts to our nation’s coastlines. This data release defines the alongshore extent of overwash deposits, determined from aerial photograph analysis, attributed to coastal processes during storm events. Note: This data release was...

These data include stream water chemistry from headwater streams to large rivers across three national parks in Arctic Alaska: Bering Land Bridge National Preserve, Kobuk Valley National Park, and Noatak National Preserve.

This data release contains numerous shapefiles that describe baseline characterization of the physical attributes of the riverine ecosystems in two national parks - Ozark National Scenic Riverways (ONSR), Missouri, and Buffalo National River (BNR), Arkansas. The individual metadata associated with each shapefile describe in detail the specific process steps, source inputs for the data...

Montgomery County, Maryland Department of Environmental Protection has collected datasets to assess the health of streams since the early 1990s. Datasets include geomorphic stream cross-sectional surveys, fish and benthic macroinvertebrate counts and taxa abundance, and water chemistry data collected at the time of benthic and fish sampling (dissolved oxygen, pH, specific conductance...

Leavenworth Creek, a tributary of South Clear Creek and Clear Creek near Georgetown, Colorado contains copper, lead, and zinc concentrations that are near to or exceed aquatic life standards. The creek drains the Argentine mining district where mining was active primarily in the early 1900s. In the summer of 2012, the U.S. Geological Survey (USGS) conducted a metal-loading study using...

This dataset includes hourly stream temperature data for 139 temperature logger sites throughout the Lahontan Basin Region of Northern Nevada and Eastern California. Data loggers were part a study beginning in 2017, with data available through 2019 for most locations. The spatial data layer contains site locations, geographic information, data summaries, mean August stream temperatures...

This U.S. Geological Survey data release consists of a tabular dataset containing stream temperature data. Data were collected every 12-hours from 15 sites in Soldier Meadows, Black Rock Desert - High Rock Canyon Emigrant Trails National Conservation Area, Nevada. The sites were established by the Bureau of Land Management - Winnemucca District Office in 2017. The data release includes...

This dataset includes continuous data on water temperature, dissolved oxygen, conductivity, and photosynthetically active radiation (PAR) from low-order streams and main-stem rivers in Northwestern Alaska. Water temperatures were determined using a HOBO Water Temp Pro v2 (Onset Computer Corporation, Bourne, MA, USA) with ±0.2 °C accuracy. Dissolved oxygen was measured using HOBO U26...

This data release supports an analysis of changes in dissolved organic carbon (DOC) concentration and in the slope of the concentration-discharge relation in the Sleepers River Research Watershed W9 near North Danville, Vermont 1991 to 2018. The data release includes pre-processed model inputs and model outputs. W9 is a 40.5 hectares forested sub-watershed of the Sleepers River Research...

The Tenaya Lake Water Budget Study seeks to quantify and understand the water balance within the principal snow accumulation and runoff yielding zone in the Sierra Nevada Mountains. The Study operates stage sensors and data loggers to record Tenaya Lake inflows, water surface elevation, and outflow, with continuous annual data collection for the 21 square-kilometer watershed located in...

This dataset includes streamflow measurements collected at six sites in Pinnacles National Park during 2018. Data collection occurred at times when the streamflow did not include runoff from precipitation. The wading method was used to measure streamflow (Nolan, K.M. and Shields, R.R., 2000, Measurement of stream discharge by wading, U.S. Geological Survey Water-Resources Investigations...
