My local creek usually runs about 5 feet deep. There have been times when I've gone when it's at 10 or 11 feet. No luck, can't get to any good holding spots, but I had to go. I even had to wade thru thigh deep water just to get to the creek.
Oh, and the same outcome as you had.


PS The creek is at about 2.5' right now, but it's just to blasted HOT to go out there.
