AUSTIN, Texas - After toxic algae tied to the death of several dogs was found in several Central Texas lakes during off-season, the City of Austin has come up with a plan to monitor three lakes. Another benefit to adding plants is that they absorb the nutrients in the pond, helping prevent algae blooms. Phoslock is used in highly fertile waters to restore water quality and reduce algae growth. Small pond owners can add a non-toxic dye to the water to help control the excess algae growth. The FAP provides financial and technical assistance to local and state governments, tribes, and special purpose districts to prevent and control excessive freshwater algae growth (cyanobacteria). When there are excess nutrients in the lake, Cyphers says algae can grow to choke out the light underwater plants and animals depend on. 4) What steps do other states take to combat its growth?
