Little Klickitat River TMDL

Ecology awarded Grant #G1200337 to the Central Klickitat Conservation District (CKCD) to conduct temperature and fecal coliform monitoring for the Little Klickitat River TMDL and Swale Creek 303d listings because there is strong evidence for temperature and fecal coliform exceedences affecting beneficial uses.

Several study-area water bodies are included on Ecology’s 303d list of impaired waters, including:

  • Blockhouse Creek,
  • Bloodgood Creek,
  • Bowman Creek,
  • Butler Creek,
  • Little Klickitat River
  • Little Klickitat River, East Prong
  • Little Klickitat River, West Prong
  • Mill Creek
  • Spring Creek
  • Swale Creek

Beneficial uses for the waters in the Little Klickitat River, its tributaries, and Swale Creek that may be impaired by temperature and fecal coliform exceedences include…

  • Recreation: fishing and swimming
  • Fish and Shellfish: Steelhead use lower reaches for spawning and as a migration corridor to upper, more favorable spawning sites on the Little Klickitat, Bowman Creek, and Butler Creek. Resident rainbow trout use the waters for migration, rearing, and spawning. Spring chinook, cutthroat, and coho use the lower reaches of the Little Klickitat for rearing and spawning during the winter months.
  • Water Supply and Stock Watering: Agriculture extracts water for irrigation and stock watering.
  • Wildlife habitat: Riparian areas are used by a variety of wildlife species which are dependent on the habitat.

Central Klickiat Conservation District has had a stream monitoring program since 1996 to obtain a baseline for temperature data . Currently, the water monitoring technician downloads data from 39 seasonal sites total in both Central and Eastern Districts. In 2010 district technicians helped Klickitat County and WRIA 30 Planning Unit to site and install 5 permanent gaging stations in the Little Klickitat River and Swale Creek which monitor stage year round. We have assumed responsibility for the long term operation and data management for these stations. Each site is monitored for flow, dissolved oxygen, temperature, turbidity, pH and specific conductivity, with the exception of two stream gaging stations where only stage and flow measurements are taken. In addition, four sites have samples taken for fecal coliform measurements.
