USGS gage 11289650 Toulumne River Below LaGrange Dam Near LaGrange CA

Federal Priority Streamgages (FPS)

Federal Priority Streamgages (FPS) are automated stations that monitor water conditions in streams and rivers throughout the country. Originally established in 1999, these are important for meeting specific long-term needs of the Nation. The FPS Network was recently re-prioritized which resulted in size of the network increasing to nearly 12,400 locations.

Intake efficiency field results for Federal Interagency Sedimentation Project bag samplers Intake efficiency field results for Federal Interagency Sedimentation Project bag samplers

The Federal Interagency Sedimentation Project (FISP) standardizes and advances sediment science among federal agencies. It is important to ensure that the FISP bag samplers perform isokinetically under all tested and approved conditions and collect samples that are representative of the stream or river cross-section. A measure of a sampler’s isokinetic behavior is its intake efficiency...

Monitoring the pulse of our Nation's rivers and streams—The U.S. Geological Survey streamgaging network Monitoring the pulse of our Nation's rivers and streams—The U.S. Geological Survey streamgaging network

In the late 1800s, John Wesley Powell, second Director of the U.S. Geological Survey (USGS), proposed gaging the flow of rivers and streams in the Western United States to evaluate the potential for irrigation. Around the same time, several cities in the Eastern United States established primitive streamgages to help design water-supply systems. Streamgaging technology has greatly...

U.S. Geological Survey continuous monitoring workshop—Workshop summary report U.S. Geological Survey continuous monitoring workshop—Workshop summary report

Executive Summary The collection of high-frequency (in other words, “continuous”) water data has been made easier over the years because of advances in technologies to measure, transmit, store, and query large, temporally dense datasets. Commercially available, in-situ sensors and data-collection platforms—together with new techniques for data analysis—provide an opportunity to monitor...

Effects of impervious area and BMP implementation and design on storm runoff and water quality in eight small watersheds Effects of impervious area and BMP implementation and design on storm runoff and water quality in eight small watersheds

The effects of increases in effective impervious area (EIA) and the implementation of water quality protection designed detention pond best management practices (BMPs) on storm runoff and stormwater quality were assessed in Gwinnett County, Georgia, for the period 2001-2008. Trends among eight small watersheds were compared, using a time trend study design. Significant trends were...

Sediment acoustic index method for computing continuous suspended-sediment concentrations Sediment acoustic index method for computing continuous suspended-sediment concentrations

Suspended-sediment characteristics can be computed using acoustic indices derived from acoustic Doppler velocity meter (ADVM) backscatter data. The sediment acoustic index method applied in these types of studies can be used to more accurately and cost-effectively provide time-series estimates of suspended-sediment concentration and load, which is essential for informed solutions to many...

Surrogate Analysis and Index Developer (SAID) tool Surrogate Analysis and Index Developer (SAID) tool

The use of acoustic and other parameters as surrogates for suspended-sediment concentrations (SSC) in rivers has been successful in multiple applications across the Nation. Tools to process and evaluate the data are critical to advancing the operational use of surrogates along with the subsequent development of regression models from which real-time sediment concentrations can be made...
