Obviously, the Letort has changed a lot, but no SO much in my lifetime. (I’m talking about the old Limestone Springs, current FFO section). Things spread out on occasion as weeds pop through the water’s surface, however for the most part the stream width seems essentially the same to me as it did when I first laid eyes on it in the 1970's.
I can't comment on water depth as I never wade and have only crossed the creek by wading a handful of times, but that LOOKS the same as well.
The weeds come and go but there were always more from below the “Big S” on up through Trego's and that seems the same more or less however, the “Barnyard” used have a lot of elodea & watercress and now there isn’t anywhere near as much.
The biggest change I’ve seen is the flooded areas from upstream of the "Vince’s Meadow" pavilion trail to a spot about 50 yards downstream from the ‘”Big S,” and below the spring confluence at the “Barnyard” to the I-81 bridge.
I noticed that area getting muddier & muddier and more under water from the mid-to-late 1990’s onward, especially after several of those back-to-back 100-year flooding events we had back then. The water level also appeared to go up, so instead of having maybe an inch or two difference between the bank and the water, the stream was now level with the bank and spilled over if it rose even a fraction during a storm.
The standing water on the bank would never get the chance to recede before the next rainstorm came and this went on and on for years until the stream bank disappeared under water.
Before this flooding, it was a piece of cake to walk along the bank from the I-81 bridge all the way to Otto’s & beyond. Now, even though the Barnyard is dry above the spring, inching along the old fence line below the spring confluence by the house is almost impossible without walking IN the water and spooking fish, and just below the “Little S” the streambank is now permanently under water.
I heard many theories about this “spreading” of the creek or raising of the water levels over the years, with the blame placed on either the quarry or siltation caused by general overdevelopment in the valley.
The last time I was fishing above the Quarry Meadow, it SEEMED to me that there is now a LOT more water coming from the quarry in that little raceway than in year’s past so maybe there is something to the quarry theory. I also haven’t seen that raceway withOUT water in years, as I did in the past. There was also a sinkhole problem in the Quarry Meadow maybe 20 years ago.
Those warning signs were downright terrifying…
There was/is a gauge on the Letort but I don’t know if it was tied into the USGS system or info is gathered from it by anyone. It would be interesting to see that data from the 1980’s until the early 2000’s if it is out there anywhere.
