Mysterious Blobs at Lake Grapevine


The "thing" at the lake is really a freshwater invertebrate called moss animals.

Each "blob" is a colony of millions of tiny organisms called zooids. The colony exudes a protective gelatinous material that makes it resemble a big ball of jelly. They eat the microscopic plants and stuff that is floating in the water. They clean the water. When they dry up, they turn to a paper like substance that crumbles and disintegrates. They cause no harm and their presence signifies good water quality.

Lake Grapevine

Mike and I went to Little Pete's to check on the water levels. The boat ramps are still closed and some of the picnic areas are still water covered. The water level at the dam is down to 46 feet. The highest we saw it was 55 feet. Last year I remember it being at 32 feet. A lot of the trees are still in the water. As you can see, Little Pete's had to make a make shift bridge to get to the restaurant. We found this 'thing' at the lake attached to a stick, we aren't sure what it is.
