• Description:
  During the spring of 1982, the National Marine Fisheries Service initiated a multiyear research program to define the effects of river conditions and dam operations on the current system (flow-net) in the forebay of John Day Dam on the Columbia River and to relate smolt passage behavior to the physical characteristics of the flow-net. Twelve digital, magnetic recording current meters were deployed in a grid within the restricted zone adjacent to the dam on 13 May 1982. Current velocity and direction were monitored until 3 November 1982. During this initial year, research efforts focused on gathering the first general data on flows within the forebay of John Day Dam and developing the computer software necessary to ultimately construct the flow-net model.
