Just wanted to throw a word of caution to anyone wading 4MR over the next several days/weeks. First, there's almost no water in it even at mid tide. Almost the entire flow is from the discharge. I'm guessing the storm must have really screwed with the bottom makeup near the discharge since most of the south half of the riverbed is now "waves." You'll have humps that protrude out of the water a foot and a half and one step later, you drop down into mid-thigh water. A lot of the bottom is heavily covered in silt now too, so you take a step on what you think will be solid ground, only to sink 12 inches into the bottom. No idea if this will just clear up in a few days or what, but you'll want to pay attention when you wade once everything get covered back up with water.
As far as the fishing, there was a decent size largemouth and smallmouth hanging around, along with a ton of catfish. I got to watch the circle of life, too - aka the smallie making a meal out of a sunfish. It took some interest into another sunfish I had hooked, but didn't hit it.
