Other then a "dip" on a 8 year average (twice), it seems as though the health is actually been improving, and it currently on an upswing..
What I do know is that I've been reviewing the Chesapeake Bay report card over the last two decades along with fisheries data and it's terrible.
Seems the records go back to 1986 when the bay actually got a lower score card. Over the past 36 years there have only been 6 years where the score was above 2021. Look at the chart to right in below link. Notice the pretty much steady rise since 2003. There were dips in 2003, 2010 and 2018, but it's overall an incline since 1986.

Most of the guys who are doom and gloom are comparing their success to the artificially inflated high back in early 1990's after the moratorium. There are a few guys who fished the 50's and 60's when it really was good, but not many here. I probably caught my 1st striper in the late 60's or early 1970. I can say that my success nowadays is much better then it was in the 70's in the upper bay. Maybe my spots still produce because I don't blast everything over social media. If I take someone out and they post, they don't get invited back.
I do agree with you on the "Conservation" organization. Most all are just lining pockets.
