Grassy Pond is interesting right now because the water level is so low, and it really is “grassy”.
The low water level is probably caused by all the sunny days with little rain in recent weeks. It is said that Grassy Pond becomes entirely without water about once every 10 years.
By the way, Grassy Pond develops a chorus of frogs on summer evenings, particularly when it’s rainy. Here’s a recording I made on such a night, focusing on a barred owl. The owl is interesting, but the background of tree frogs, green frogs, and loud bull frogs is interesting too.
