The DCP Water Quality and Temperature Study is one of many relicensing documents for the Devil Canyon Project (DCP) Hydropower Project Number 14797. The California Department of Water Resources applied to the Federal Energy Regulatory Commission for a new license of the DCP Project located in San Bernardino County, California along the East Branch of the State Water Project (SWP). The SWP provides southern California with many benefits, including an affordable water supply, reliable regional clean energy, opportunities to integrate green energy, accessible public recreation opportunities, and environmental benefits.

The SSWP Water Quality and Temperature Study is one of many relicensing documents for the South SWP (SSWP) Hydropower Project Number 2426. The California Department of Water Resources and the Los Angeles Department of Water and Power applied to the Federal Energy Regulatory Commission for a new license of the SSWP Project located in Los Angeles County, California along the West Branch of the State Water Project (SWP). The SWP provides southern California with many benefits, including an affordable water supply, reliable regional clean energy, opportunities to integrate green energy, accessible public recreation opportunities, and environmental benefits.

The data set contains temporal chloride concentrations (mg/L) and specific conductance (uS/cm) values for 32 wetlands and groundwater monitoring wells as well as the date(s) sampled and the laboratory where the water quality analyses were conducted. The ratio of chloride concentration to specific conductance is referred to as the Contamination Index. In this region, values greater than 0.035 are used to identify water quality samples that are contaminated with co-produced water from energy development.

Air temperature, water temperature, and specific conductance of water were continuously measured with data loggers (measurement interval = 30 min.) from 2014 to 2024 at six wadeable stream sites throughout Delaware Water Gap National Recreation Area (n = 3) and New River Gorge National Park and Preserve (n = 3). Data loggers were deployed at stream reaches where benthic macroinvertebrate, fish, and streamside bird communities have been monitored by the National Park Service since 2014. These data were collected as part of a multi-agency Regional Monitoring Network of reference (i.e., relatively undisturbed) streams throughout the Mid-Atlantic Region. Sites were selected based on their high degree of ecological integrity as inferred from previous biological surveys. Methods followed existing protocols that were consistent with approaches used throughout the Regional Monitoring Network.

Water-quality data were collected by the Providence Water Supply Board (PWSB) from tributaries in the Scituate Reservoir drainage area, October 2014 through September 2015 (water year 2015). These data were used to calculate instantaneous loads and yields of constituents in a report by the U.S. Geological Survey. Water-quality samples were collected by the PWSB either monthly or quarterly at fixed stations on 36 tributaries in the Scituate Reservoir drainage area. Water-quality samples were collected following a strict sampling schedule so that water-quality samples would be representative of various weather conditions. Samples were analyzed at the PWSB water-quality laboratory at the P.J. Holton Water Purification Plant in Scituate, Rhode Island. Water-quality properties and constituent concentrations were measured by using unfiltered water samples. These water-quality properties included pH, alkalinity, color, turbidity, and concentrations of chloride, nitrite, nitrate, orthophosphate, and bacteria (Escherichia coli [E. coli] and total coliform).
