Anyone else's duck lease turn bad lately?

My family has held our duck lease for 40 years now. We are South of Morgan City at the intersection of Bayou Penchant and Bayou Chene. For a solid 25+ years this lease was dynamite. I literally couldn't imagine better hunting. Ducks of all makes & model as well as a big specklebelly goose population. Growing up, we'd go to places in West LA and Texas as guests and often leave saying among ourselves how much better our hunting was. Game wardens would check us and remark about how we were sitting on a gold mine type lease.

Then about 10-12 years ago things started to slow down. Not just our lease, but the whole area. Limits became fewer, ducks became less and less. Saturday's shoot might be good, but Sunday was the dead sea. I noticed far less ducks in our areas that we never hunted (refuge/sanctuary areas of our lease and surrounding sections). Last year was slow, but there were a few decent shoots. But some weekends were just plain strike outs. But there were at least some ducks on the lease.

So far this year I've seen all of 10 ducks on the lease and those were way far off in the distance on the youth weekend. Opening weekend my dad and brother didn't even see a duck. Not a duck! Anywhere! They said they heard some shooting, but nowhere close. They didn't hear much from Avoca Island club either from what they could tell.

So I ask... what the heck has happened to make ducks literally not even come to an area that was once a haven for ducks? We have good water and fairly open ponds, fresh water/building healthy marsh. We have great natural feed. All the same vegitation we've had for years (aquatic grasses, japanese millet, etc). So how does our marsh literally not recieve 1 duck by Novemeber? Heck, we don't even have resident birds anymore.

I know flyways have changed due to management and agriculture stuff. But alot of ducks are still coming down. You'd think some would find a happy home in such a once thriving spot.

My only theory is predators... The bald eagle community has exploded in our area. The damn things are everywhere. But could that keep the ducks out completely?

Anyone have any thoughts or see this happen elsewhere? Anyone hunt in neighboring sections that may be seeing the same thing? Any discussion would be appreciated.
