Golden Algae-Caused Fish Kills Confirmed at Saguaro, Canyon Lakes

The Arizona Game and Fish Department (AZGFD) has confirmed golden algae toxin blooms as the cause of recent fish kills at both Saguaro and Canyon lakes.
When golden algae is the cause of a fish kill at one of the Salt River chain lakes (Saguaro, Canyon and Apache), varying degrees of fish kills are typically observed at all three of the lakes. AZGFD staff recently collected water-quality samples at both Saguaro and Canyon, which confirmed golden algae as the cause of the fish kills.
At Saguaro Lake, AZGFD staff observed small numbers of dead and dying threadfin shad (less than 500), along with a handful of other species including largemouth bass, bluegill and catfish. At Canyon Lake, about 1,000 dead threadfin shad were observed; no other species were affected at that time. Read more
