Grew up in Rockford. Have spent Countless Hours fishing the Main Snake from Firth all the way to American Falls Reservoir.
A few tips
You need a boat to fish this area most effectively. Short floats from the Porterville Bridge down to Blackfoot or from Blackfoot down to the Cherry Plant Access on Thomas rd are great. The diversion below the Porterville Bridge can usually be navigated but scout it from the road first. Its not as tough as it looks.
If wading try the area below the Porterville Bridge Just upstream from I15 Sometimes you can wade all the way across the diversion between the two bridges. The holes on the other side are best because they don't see to many angles Don't get crazy and try to get over there if it doesn't look good or anytime in the winter. The main hole below the diversion has been good from time to time. Have attached a pic of a fish I caught several years ago in this stretch.
Try swinging a big black wooly bugger with a Cone head and a Marabou tail with a little flash on a full sink line. When i fly fish the Main Snake in that area I usually throw Big Ugly Streamers from a boat with a 7wt and the deepest sinking line I can find. Nymphing with a smaller black wooly like the one described and a very small size 20 anything should be productive too.
The River from Tilden Down is the most productive stretch of the Main Snake. Gotta have a Jet Boat to fish it though. Takes more than a full day to float it and fish. Numerous springs keep the water ice free all winter and the fishing in late February is Awesome. South Fork outtfitters guides that section. Should tell ya something.
Good luck.
Good luck
