Vegetation patches increasing on our lake; good or bad?

Lets start with that i do not know what the vegetation is. But it is spreading in the lake in large patches. Is this good or bad for the fishes health? To thick to drive through and i would hate to drive into during a night fishing .

First we need some pictures of it to help determine what it is. If it is Giant Salvinia, you have a big problem on your lake.

Will a picture of what it looks like on the top of the water be sufficient? Or will you beed a picture of a piece pulled out?

what lake?

Both would be the best, but anything will give us a clue.

Take a good close picture of it laying in your boat. Generally grass if great for the fish.

Sounds like Salvinia or water hyacinths, neither is good!

Yep. Probably hyacinths, you can normally run through salvania.

Canyon Lake, Texas . Hopefully out today to get a picture and post.
