With the increase in water levels this spring to a lot of our lakes, there's a lot of flooded vegetation in shallower water. Just curious if anyone knows how long this vegetation takes to decompose or lay down?

Sort of depends on what type of vegetation you are referring to. Some of the grass type will not last long but if it's small stick ups they will last longer maybe into next spring. If it's button willows, years.

I've also been wondering about this. Some of the vegetation at my favorite lake include willows and tamarisk trees. I'm thinking several years on these. Should make for better fishing in the long run, though.

I think mostly just thick grass type. It's just annoying bottom fishing anything shallow around here now since the major increase in water level. But I am thankful for the rain no doubt.
