I fish in nyc and I usually fish green pumpkin wacky rig senkos in public lakes. I don't know what's wrong but I only get 1-2 dinks per day. Is NYC just a bad place to fish or am I doing something wrong? Any suggestions welcome.

I only have seen the Central Park lakes. They aren’t the most productive lakes. They are fed by rainwater only so get a bit stagnant. I don’t know how much fishing pressure they get but they are the only thing fishable and surrounded by a couple million people.  Not the place I would generally choose to fish but if that’s what you got, that’s what you do. 

if prospect park or where you are fishing is similar, then I might consider a little darker colors and downsizing. Darker because of the usual dinge color of the water and probable algal blooms this time of year. Smaller due to pressure and smaller fish (bait and game) generally.  If it were me fishing it, I’d probably go to a weedless Ned rig and mix up swimming it and dragging it. You’ll have to experiment with colors, but hot snakes/yoga pants(black)/black blue would be my starting point. Also a half 5” senko in green pumpkin is a good choice (I have liked tipping the tail with chartreuse).
