If you observe an algal bloom, ADEQ recommends: Another type of algae commonly found in Arizona is golden algae. As the planet warms, water temperatures climb and rain gets heavier, meaning the bloom risk increases. The environmental conditions that support golden alga are broad, and little is known about the specific and complex conditions that allow it to gain a competitive edge over other species, or about what causes a bloom that results in fish kills. Fish kill and other lake observation information suspected to be connected with golden alga blooms may also be emailed to the department at goldenalgae@azgfd.gov. Most of the documented golden alga blooms and associated fish kills occur during seasons when water temperatures are between 55-80 degrees Fahrenheit.
