Notes on the DART River Environment Dataset

USACE Data Disclaimer: These data are furnished with the understanding that the Corps of Engineers makes no warranties concerning the accuracy, reliability, or suitability of the data for any particular purpose.

Inflow, Outflow, Spill, and Temperature (Scroll Case) data are collected at the project (dam). Spill Percent is calculated by DART from the Outflow and Spill values. Temperature (WQM), Barometric Pressure, Dissolved Gas and Dissolved Gas Percent are measured at Water Quality Monitoring stations in the forebay and tailrace of most projects and other key locations in the basin (prior to 1995, these data are from a variety of sources within the U.S. Army Corps of Engineers). Turbidity is measured in the forebay or in the fish ladders at a project. Elevation is measured in the forebay of a project.

Bonneville Dam, 18 July 2006: The USACE initially reported incorrect hourly Bonneville spillway discharge for 2002-2004. DART is reporting the USACE's Recalibrated Spillway Discharge at Bonneville for this period. The Water Quality reports for BON, CWMW, CCIW, and WRNO include the recalibrated spill at Bonneville.

Wells Dam, 13 August 2012: The DCPUD has requested the water temperature data reported as the "Wells Scrollcase Water Tempurature" obtained for DART from prepared USACE text files be removed as erroneous. The Wells project does not report scrollcase water temperatures. This data has been removed from the publicly accessible DART dataset.
