Bacterial outbreak found at Arizona’s largest state hatchery: A list of which lakes may be affected

Page Springs Hatchery

Arizona officials have halted all fish stockings from the largest state-run hatchery because of a bacterial outbreak among its trout.

The Arizona Game and Fish Department announced Friday a temporary ceasing of stockings from Page Springs Hatchery, which is north of Phoenix in Cornville.

The agency said officials noticed fish deaths in early June but with symptoms not associated with diseases previously seen there.

A University of Arizona lab last week identified the pathogen as a naturally occurring bacterium that had not been found in the state before. The bacterium, however, were discovered in California hatcheries in 2020.

The department is working to determine the source.

Officials are warning that it’s possible more than two dozen lakes, ponds and other bodies of water in Arizona were stocked in May and June with fish carrying the bacteria.

These are the bodies of water included in the list: 

  • Ashurst Lake
  • Big Lake
  • Bunch Reservoir
  • C.C. Cragin (Blue Ridge) Reservoir
  • Cataract Lake
  • City Reservoir
  • Dogtown Reservoir
  • Fain Lake
  • Frances Short Pond
  • Goldwater Lake (Upper)
  • Kaibab Lake
  • Kinnikinick Lake
  • Knoll Lake
  • Lynx Lake
  • Mingus Lake
  • Mormon Lodge Pond
  • Nelson Reservoir
  • Oak Creek
  • River Reservoir
  • Rose Canyon Lake
  • Santa Fe Reservoir
  • Tunnel Reservoir
  • West Clear Creek
  • Wet Beaver Creek
  • Willow Springs Lake
  • Woods Canyon Creek
  • Woods Canyon Lake

Anglers are advised to follow U.S. Food and Drug Administration guidelines on how to properly cook fish.

Fish from the Canyon Creek and Tonto Creek hatcheries will replace stockings from Page Springs this month.
