WaterQualityWatch

WaterQualityWatch provides access to real-time water-quality data collected at more than 2,000 stream sites throughout the United States, including streamflow, water temperature, specific conductance, pH, dissolved oxygen, turbidity, and nitrate.

WaterAlert

The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.

NWIS Current Water Data (Real-Time Data)

The USGS provides real-time or near-real-time conditions water data at sites across the Nation. Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to USGS offices every 1 to 4 hours, depending on the data relay technique used. Recording and transmission times may be more frequent during critical events.

USGS Mobile Water Data

The USGS Mobile Water Data site highlights USGS current conditions water data in a mobile-friendly website, allowing users to monitor conditions at a favorite river or stream or locate nearby monitoring locations. All USGS current conditions water data is available.

How We Model Stream Temperature in the Delaware River Basin

Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.

How We Monitor Stream Temperature in the Delaware River Basin

The USGS has been monitoring stream temperature in the Delaware River Basin since 1901, and has amassed over 650,000 daily temperature measurements. This data visualization story explores temporal and locational patterns in stream temperature observations, and how spatial variability and data gaps add complexity to prediction efforts.

Land Remote Sensing Satellites Online Compendium

The Land Remote Sensing Satellites Online Compendium contains details about past, present and future Earth observing satellites and the sensors they carry.  This resource has been developed and is managed by the Requirements, Capabilities and Analysis for Earth Observation (RCA-EO) team at the USGS Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota.

From Snow to Flow

A majority of the water in the western U.S. comes from snowmelt, but changes in the timing, magnitude, and duration of snowmelt can alter water availability downstream. This data visualization story explores what changing snowmelt means for water in the West, and how new USGS efforts can advance snow science by modeling snowpack and snowmelt dynamics and linking these results to streamflow.

Multisource Water-Quality Trends in the Delaware River Basin

Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin.

Measuring stream flow

In this explorable interactive tool you will investigate a series of charts and sliders to explore how water level, water velocity, number of measurement points and stream channel shape influence stream flow. Great for use in the classroom, especially for student curious about coding.

Lowell Minor Planet Services - asteroid.lowell.edu

The USGS Astrogeology Science Center has collaborated with Lowell Observatory to create a graphical interface for their main asteroid characterization web portal. The portal uses data from the astorb database maintained by Lowell Minor Planet Services.

Data Query for the Water Quality of San Francisco Bay Project

Since 1969, USGS has collected water-quality data along the deep-channel longitudinal axis of the San Francisco Bay-Delta system at 37 fixed locations spaced 3-6 kilometers apart. The Water Quality of San Francisco Bay Data Query provides access to the entire dataset.
