I used to fish the stretch between North and 1st Ave. a lot. I think the piers you're referring to are the abutments left from the old Armitage St. dam that was taken out around 5 years ago. Before then I caught lots of pike and rock bass right there. After the dam went away the fishing declined.
Take Aux's advice about other area. If you park at Evans go left when you hit the river, past the bridge (don't cross it) and fish your way down to the creek that drains the wetland you walk thru on the way to the river. Be sure to fish the laydowns. One of the biggest I've caught around there was 28" on a jointed crankbait.
You can also park in Maywood at Lake & 1st and access the river from there. They recently put in a canoe launch there.
I think Aux is referring to Silver Creek. It joins the DPR from the west between North and Chicago. It's anything but silver.
Keep calm and fish on...
There's a fine line between fishing and just sitting there looking stupid
