Bloom Description

No sample collected, located within the same zone as Cayuga Marina but ~1 mile south. Volunteer reported: It’s 61F and sunny this morning with a gentle breeze. We had .18” of rain here overnight and before that we had .69” four days ago. This part of our zone is not a priority site but we will try to visit the Cayuga Marina at the north end of our two mile zone to check for any bloom there.
