Arizona Game and Fish, City of Tempe work together to keep Town Lake fish healthy

TTLpicWebTEMPE — The City of Tempe and Arizona Game and Fish Department have cooperated on a management plan to help fish in Tempe Town Lake during the final phase of construction of the new dam.

“Our natural environment is extremely important to Tempe. We are grateful to have the expertise of Arizona Game and Fish and our longtime water quality expert, Aquatic Consulting, as we undertake the final phase of our dam construction,” said Tempe Public Works Director Don Bessler. 

Arizona Game and Fish and the City of Tempe are working together to save as many fish as possible while the previous dam system is being removed. Tempe has to move the water out of Town Lake into an SRP canal system, leaving the lake without water for approximately three to five weeks.

The cooperative effort started several months ago and includes:

  • Not stocking fish as normal in fall 2015 in order to lower the number of fish that would need assistance.
  • Removing the limit on the number of fish that people could catch at Town Lake.
  • Moving a representative portion of some fish into protected areas of the lake that will retain water.
  • Using fish-friendly pumps that allow the fish to move into the SRP canal system along with the water.
  • Monitoring pockets of water within the lake that contain fish, since fish can survive in small space for such short amounts of time.



This planning has reduced the number of fish that need assistance. Several thousand people live and work around Tempe Town Lake and millions come to visit each year. It is the intent of both Arizona Game and Fish and the City of Tempe to minimize the impact of this project for these people.

“Some people have asked why we can’t move fish into other bodies of water, such as nearby Canyon Lake. We can’t do this because of the possible transfer of fish-related bacteria and diseases,” said Scott Gurtin, AZGFD Community Fishing Program manager. “This plan represents the best and safest way to conserve fish and keep our waters healthy.”

New fish will enter Town Lake when the lake is refilled. The water will come from the Central Arizona Project canal system, which has many varieties of fish. Insect-eating fish will also be stocked at that time. Arizona Game and Fish will restock Town Lake with other varieties at the appropriate times.

Town Lake is expected to be completely full and operational by approximately April 30. The new dam system is expected to last more than 50 years. Read more.
