Today is Wednesday, Aug 21 and apparently the NH DES posted two new orange warning signs, yesterday Aug 20, into the shoreline sandy town Waterville Valley beach, close to the pond water, "Unsafe for Swimming or Wading." The water surface looks very clean and clear with no visible green/blue Cyano growth and the water temp has dropped a lot in the last week probably dropping from about 70 down to 64, or so. Corcoran Pond is a beautiful 7-acre, dammed resort water body in Snow's Brook with a large town dock, kayak, canoe and sup rentals, and a large town sandy beach.
In the last seven days, Aug 15-21, the Lake Winnipesaukee water temp has dropped from 75 down to 70 which is a very steep decline. Is noticed these new Cyano warnings for Alton-Wolfeboro-Tuftonboro, Lake Winnipesaukee come with water temperatures getting colder, relatively fast, so maybe the colder water and the Cyano is related.
I went swimming about 100-yards in Corcoran Pond two days ago, Monday Aug 19, for 100-yards and it was wicked cold, 65-degrees, and now if I could go back in I would definitely wear an O'Neal thermo top and a neoprene vest and a foam noodle swim belt. 64-degree water on a 60-degree, cloudy day is just too cold and not too safe for swimming the deep water, alone.
When the orange warning NH DES signs are posted into the sand, people have still been allowed to swim and wade the water at Weirs Beach, Laconia. In Waterville Valley the Corcoran Pond is closed to swimming and wading and last July, 2023, I got evicted while swimming Corcoran Pond by two local cops ...... "hey you, this pond is closed, you see those orange signs, GET OUT, is not safe for swimming!"
I always do the breast stroke or side stroke, resting long distance strokes, and keep my head and face out of the water in Corcoran Pond. Maybe this swim style can be named the Cyano stroke ...... ha-ha-ha! .....
