1 River Environment parameters are not available at all locations.
Inflow, Outflow, Spill, and Temperature (Scroll Case) data are collected at the project (dam). Spill Percent is calculated 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.
The USACE initially reported incorrect hourly Bonneville spillway discharge for 2002-2004. As of 18 July 2006, 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.
Notes on the DART Smolt Index Dataset
Data Disclaimer: These data are preliminary and have been derived from various sources. For verification and/or origin of these data, contact the operators of the Fish Passage Data System.
Rear Types: The Unknown rear type category is a mix of wild and hatchery fish, so when unknown is listed along with hatchery and/or wild this means that the number of hatchery or wild fish counted is only a portion of the total number of fish with that rearing disposition. Since the year 2000, the only individual Rear Type category in the DART database is Unknown.
See Smolt Monitoring Meta Data (based on FPC's May 2, 2005 version) for details about the Smolt Monitoring program and data. See the Smolt Rearing Dispositions web page (based on FPC's December 13, 2001 version) for details about which individual Rear Type catoregories are possible by Species, Year, and Data Collection Site.
