I have ventured through that area more than a few times, but never seen it quite that choked with trash. Usually the areas upstream by the dam have less debris, but the lower portions down across from where the pipeline enters on the Garfield side are more prone to collect the garbage. A few years back there was a scout group or something like that who cleaned it up very well, but the Passaic being what it is, it just cloggs up again after a few storms with all the junk washing over the falls from upstream.
One of the biggest issues is access to that park. The gate off the access ramp to Route 21 is always locked. I've usually had to walk across the river from the Garfield side wearing my waders.
I've also heard stories about homeless people living in there, but have never seen them when I've walked around in there. It is a nice little park though, with gravel paths and a few benches and signs, only problem is that gate that's always locked!
