Duck Hollow trail access

Not sure about the actual trail, never went down that far, but people do. The area in general is a very popular spot. Lots of folks fishing off the wall / parking lot and some wading out in front. I've fished it plenty with no trouble.

Mags, it's fairly shallow for a good bit with a couple deep holes. It does get fished heavy as Mr. Z said. I've fished it many times from my boat with very good success on Smallies & Spots. I have also caught a lot of white bass, small sauger and small walleye. I'd stick with the jigs, not worth losing a diver or two. IMO wading out would be a better idea to get away from the crowds a bit.

Good info from TheBlueLagoon.  I've waded it quite a bit over the years. Just wading in river shoes and shorts (my skin has never melted off). It is mostly shallow but I've heard of a few holes out there that produce walleye and I believe I found them to be within casting distance. I wouldn't waste time fishing from the wall - you need to haul what few fish you catch up about 20 ft. and drop them back down to release them.
 
Usually I get a fair amount of small smallies and spotted bass (14" and under) a few times a year and I hear white bass come in at times. But last year was strange. I fished it about 6 times in the early spring without a bite. A few guys would fish there with livebait and kick my butt big time. Took a while to figure them out. Once it gets too hot out I don't bother with the rivers so no idea how it fishes in the summer.

Turd Hollow!

I used to live about a mile from there, in Greenfield, about 15 years ago. I fished it about 1-2 times per week, if I didn't want to travel to some of the better river spots. I'd much rather fish some of the popular Allegheny spots or Ohio spots if traveling though. Even some much better Mon spots heading away from town a little further. I wouldn't make a special trip. Safety wise, I never had any issues.

I would never wet wade that spot. Also never fish if any sort of rain is in the forecast. There is a combined sewage overflow right up stream from the "pier" and stream mouth, that will have raw sewage dumping into the river with anything more than a light rain. I witnessed some guys wading out there and caught in the CSOs opening up, disgusting. I used to wait at least two days after a rain, and still had days that there was toilet paper on my line... If you follow that, and hit it right, it had put up some great days. I did most of my fishing wading out on the creek mouth sandbar. Back when the wipers were stocked, I had a few good days on them. A lot of white bass, sauger and smallmouth too.

If you really want to see something disgusting, go right after a good rain. Carp will stack up right outside of the CSO and eat the crap coming out...

Ugh... Not even gonna check it out. I'm just looking for something a hair closer to hone that I don't have to use a ton of gas to get to. I'll scout the Yough I suppose.

That Summerset has been developing for a while.  I'm not sure if they have any access (besides construction access) from below, so doubt that many are venturing down.  It would be nice if they cleaned it up and made for some river front park developement.  Until the CSOs are fixed, cleaning it up wouldn't really be worth much.  I think it is in the $30M range, just to plan the fixes to the CSOs and around $4B to actually do it...
 
Don't let this scare you off on fishing the rivers.  Hold off two days after a rain, and you should be fine.  The further from town, the cleaner it is, at least sewage wise (can't say the same about industrial waste, since almost all of the city's industry is gone).  Definitely still some sewage outside of town, but less density.  The Yough probably would be a better place to target, if coming from Greensburg.  Unless you are focusing on flatheads, the Yough has about the same fish available.  From Greensburg, you can probably access around McKeesport relatively easily, not really sure of any safe places around there, but sure there are some.  The Dravosburg side should be safe if you can find access.  If you are close to 70, you can swing down to 51, and hit Elizabeth.  There is a park under the bridge that is safe.  A good variety of fish and don't need to wade.  Not sure about flatheads, but can't imagine they aren't there.

There are many small rats down there too.  One night I was fishing from the wall down near pee corner using cut bait and apparently got enough fish juice on the handles of my reels to coax the rats into licking them.  Later that night they stole half a trout out of the bait bag.  They weren't those big Erie rats, maybe 10" at most.   

I hear ya, I am afraid of being "cleaned up" from the area.   
 
The google sat. images seem to be far behind.  They added a nice kayak/canoe launch on the east side of the mouth.  You have to wade out ~20' to get to anything deeper than 3" of water, but it is better than before. 

I fished that area by boat this weekend. Cookie cutter smallies- white bass - sauger in the Costco area. Anyone fish the Streets Run point area? Didn't pull anything out below sand castle. Wind got a little annoying.
