Mostly sunny with high cirrus clouds and no rain in the past 24 hrs. Some seagulls, ducks, cormorants, swans and loons around on the water and in the air…dragonflies too. Spoke about Water Rangers testing with some groups of people walking around the dock area and some fishermen who were coming in with their boats who all were asking about what I was doing and seemed appreciative. Fishermen had been catching wallets and small mouthed bass.
