If you didn't mark location on the map then select the closest area where you made your observation.
Using the density scale (click button at end of this form to see scale) choose the best option (within a 1.5 inch circle) that best represents what you see. The scale works best for cyanobacteria that produce visible colonies such as Gloeo.
Feel free to add other observations such as windy day, calm conditions, or saw surface scum.
