Bloom Description

Community member reported: The weather is about 63° and there’s relatively little wind right now. The weather is very mild and it’s sunny. The outbreak that I’m seeing is not super dense but looks like a mild outbreak. It does have the characteristic yellow dots all over the surface of the water. it is drifting southward. There is no weed cutter boat near this area. It is a Sunday morning and things are very quiet. I’m not seeing any fish die off. It looks like it is either a bloom that is just ramping up or one that is fading out.
