Bloom Description

North end of the park shoreline seemed to be affected. South end of the park water was clear and free from the HAB. HAB looked to extend about 6 feet from the affected shoreline. Did note one dead fish in the water. Skies were clear with some scattered clouds. Temperature was warm but not too hot. I believe about 75F.
