A couple of options Brandon Percival suggested to me: (And I use both....)
1. Park in the Osprey Picnic Area lot of Lake Pueblo State Park and walk east to the gravel pit/lake on the paved bike trail. (Just before getting there I usually angle right on what seems to be an old road and then you can walk closer to the shore where you like.)
2. Park in the state park's "
Chain of Lakes and Arkansas River Access" parking lot on Hwy 96 just east of the "Goodnight Barn" and walk north to the gravel pit/lake. You'll actually need to walk a bit northwest to cross a bridge, but it's pretty obvious on site. You can also check the pond just north of the parking lot.
Good birding,
