What type of pond moss or algae is this?

Asked July 4, 2016, 4:04 PM EDT

This pond is called a "fire lake" in the community in which we live. Seems to be slowly fed off an underground finger from a large lake and we are near the end of it. It is shallow but we have no idea as to depth. This year, we have noticed this lacey moss looking plant growing in the water and it is spreading. We have not seen flowers coming from it even though it appears to strongly favor bladderwort. There are frogs and fish in this pond and it is loaded with minnows. At the edge of the water there is a swampy smell. We don't own the fire lake, the backside of our property borders it. We have asked our HOA to get several trees out that have fallen in the water, but it will probably be quite some time before they get to it. We don't know if we need to ask them to address this plant growth or let us treat our section of it, since we don't know if it is harmful. I have pulled some it it up and it is either a free floater or is slightly attached to the sentiment at the bottom. I am attaching 3 photos. Oneis a close-up of the plant and two are of the water. Thank you. Alice Lammonds.

Hi Alice. The close up picture does resemble bladderwort. Bladderwort is a free-floating plant. You should see flowers above the water during the summer though. Bladderwort itself is not harmful. If your pond is completely impounded, then triploid grass carp would likely be the best option if you choose to manage the plant. They would need to be stocked in fall (or spring) at a rate of 15 fish per acre of pond. Please let me know if you need additional information.
