Water Temperature Control and Areal Oxygen Consumption Rates at a New Reservoir, and the Effects on the Release Waters

  • Richard A. Cassidy
  • Patrick E. Dunn


The potential environmental effects of dams on the Rogue River have long been a specific concern to people of the Rogue Valley, Oregon (U.S.A.), and a general concern to the residents of the entire State of Oregon. Following serious flooding in the mid-1950’s, efforts were begun to build large, multiple-purpose reservoirs (Cassidy & Johnson 1982). When the U.S. Army Corps of Engineers built two dams in the Rogue River Basin, an innovation in water release methods using selective withdrawal systems was utilized by the Corps’ Portland District to reduce the harmful effects of the dams on the receiving streams. Selective withdrawal systems allow the removal of water from one of a number of different levels in a reservoir, or from a combination of levels, to utilize the best quality water in the reservoir for discharge downstream.
