Reading Water - Tailwaters


Tailwaters

  • Water comes out of a dam (lake, reservoir etc.)
  • Water coming out of the base of the dam is cold
  • Water coming over the top of a dam (spillway) is warmer
  • Access limited closer to dam for security reasons (dams that produce electricity)
  • Fish congregate in section between dam and fishing area and may be pushed out during higher releases
  • Fluctuating levels based on needs of power company, water level behind dam, recreational uses (kayaking/rafting)
  • Water is crystal clear closer to dam, runoff and feeder streams contribute to water levels and loss of clarity down stream
  • Year round fishing
  • Water temperature is constant closer to dam and remains unfrozen in winter
  • Water begins to freeze downstream from the dam in winter as the stream is cooled by ambient temperatures
  • Plants and animals grow year round closer to dam = increases chances for huge trout
  • Rocks and bottom tend to be slick as algae grows year round
  • Some western reservoirs were stocked with shrimp to feed stocked fish.  These highly nutritious shrimp are carried with the water release.  The trout closest to the dam get first dibs and can grow to immense sizes and display a variety of bright colors
