I have no concerns about this whatsoever, but I thought this might be interesting to post. This pond was drained last fall, and allowed to dry out somewhat briefly before refilling with well water. I'm seeing big sheets of this stuff popping loose from the bottom. I don't believe it is alive for the most part. Filamentous algae is also taking the place of the Chara that was up to a couple of feet thick on the bottom which dried out and died -- although I have no doubt the Chara will be back. You are looking down in 8 feet of water. Water is gin clear and you can see all the way to the bottom in 11 feet of water no problem which is the max depth.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.

CB1 - great pics. Are you going to remove the dead material ( nutrients in waiting) or let them decompose ?

I'm going to definitely remove whatever floats up and may even try and rake out from the shoreline and pier as far as I can, but it's doubtful I will be able to reach it all. But yes this stuff is definitely nutrient material the will fuel filamentous algae. The clear water will help in the raking to show me where I removed it and where I missed it.

What do yall mean by nutrient material? Does it have something to do with the water chemistry

JHFV all things that stay in the pond are probable nutrient loading factors. Dead weeds , excess fish food , fish waste , dead fish , bottom silt , dead plankton all of it is ready to break down into its basic elements and be re-used as nutrients by something else. The basic idea is that energy that goes into the pond never goes away it just changes form ( example fish food is energy and does not vanish when put in the pond it just changes to bigger fish , more fish waste and the part not eaten adds to bottom silt nutrients. Yes it does very much have the ability to effect water chemistry.

Yes good explanation Eric. Also think of decomposed plant material as a kind of aquatic mulch. When you pull this kind of material from your pond it breaks down into a kind of black oily muck. In fact there is research going on to convert algae to oil.
