Has someone told you that the fish are biting on the all ameican?
Where do ya want to go or where have you been?? Dam dude, the Valley is a huge place. I've put 400-500 mi on my truck once I got down there. I hunt/fish over in the Winterhaven/Yuma area. We even found a place where they stock trout! I have hunted from niland to calexico to brawley and holtville.
Sounds like you need to do a scouting/road trip.

Buy a map of the area when you get down there. Like I said bridges are the hot spots on any of the canals.
The water temp on the main river was 52 a couple weeks ago. They were letting a lot of water out of imperial dam. Cut outs along the main river were 54. Figure 56-58 in the canals depending on the watering schedule(s) and levels. Water level in the all american is down about 2' over where we hang out. Not the best time of year for fishing but you can do ok.
Good luck!
