A. Waterfall - A horseshoe shaped waterfall that offers good opportunity for trout. Be careful of the steep and rocky bank. Also, the water flow can be strong depending on recent rains, so plan to adjust your gear appropriately.
B. Hughes Crossing ("Left") - as you approach the crossing from the Parking Area and scan the area to your left, observe the rocky bottom. Note the gaps between the rock formations and where the water deepens. This area will hold trout at times.
C. Hughes Crossing ("Right") - scanning to your right, observe the water flowing over the Crossing and downriver. Note the areas where the "bubbles" are forming most. Work the seams of these areas and the "bubble line". This area will hold trout as well.
D. Waterfall to Hughes Crossing ("Left") - Along this section of the river, note the areas where the water flow slows down and/or the deeper areas. These areas are also good for trout.
E. Downriver from Hughes Crossing ("Right") - observe how the river deepens as it flows from the Crossing to the boulders rising from the water downriver. This area will hold trout. The key is being able to cast to the area and adjusting your rig based on the water flow.
F. Disabled Fishing Access - the area directly in front of this area is strewn with rocks and several boulders. Depending on the water level, they can be easily seen rising from the water. Also, if the water level is too low, trout will tend elsewhere. When fishing this area, a float versus a bottom rig should be considered to reduce lost gear.
G. Sandbar - a favorite staging point for wade fishermen as it provides good access to deeper water (H) and is a prime spot at times for trout!
H. Deeper Water - a pool accessible from the bank as well as from the Sandbar. Bait fishermen tend to do well from the bank while wade fishermen using fishing flies and spinning lures/spoons tend to do well from the Sandbar and the Rocky Shallows.
I. Channel - that runs between the Rocky Shallows and the Island that divides the river in two as it flows downstream. Trout will tend in the Channel and action can be good. Also, if positioned by the Island, access to deeper water (H) as well as the Channel (I) is provided the fisherman.
J. Rocky Creek - past the Island, the river becomes shallow and rocky with a mix of (2'-3' deep) pockets where trout will hold. Good at times as well as frustrating when the trout become lock-jawed. This is made worse when you can see them lurking only a few feet away! Be sure to tread lightly, else the trout will spook.
K. Various Riffles - another shallow run that is rocky making wading tough at times. Also interspersed with riffles that foam with water flowing past. Tread lightly as well; trout lurking nearby will spook!

A guy who works for Oklahoma Fish and Game sent me this-don't think he'd mind if I share it here.

With this map in mind, how far away do I have to park? I had a total knee replacement, still having some difficulties!
Thanks for your time and info! I will be wading.
