I grew up fishing that river. I always enjoy the hell out of going back "home" to fish it. I sure know what you mean about not being crowded, thats one of the best parts about that little river. That, and, you never know what your going to pull in. That river produces some really nice fish if you know where to find them. The Northerns are getting more and more popular also. I used to only catch them by the tomato docks and last year I landed a couple at my folks house inside the Elmore limits!
If anyone targets fish with a bow, Elmore downstream from the bridge is covered with perfect target fish! Water is really low for this time of year and fish are stacked on top of each other in the holes. The bank is pretty tall at my folks house and you can sit up on top and watch all the Gar, Carp, and Suckers swim back and forth all day long. I'd suggest parking on Rice street by the cemetery and walking down the steps into the park (just to the left of the old cemetery when looking at it). Then work you way downstream from there. Fish were stacked from the rapids to the first big bend. Or you could park at the soccer fields/park and walk your way back upstream to the rapids. Either way, it'd be a good time. I'd throw a handful of canned sweet corn in every once in a while just to watch the carp come up and eat it. So it should work for anyone wanting to catch carp on tackle.
