The Fall River is fishing nicely and ODFW has stocked some nice fish in there lately. I really encourage the local people to go early at dawn and fish to 9 or 10, and also do the evening bite after work, staying until dark. Mid Day is busy, and of course mid day is a great time to be there, but not everyone needs to all go to the hatchery to fish. It’s a 10 mile lone river and there is way more to the Fall River than the fish hatchery access. 
PMD’s and Yellow Sallys are 2 of the main hatches daily, and olive caddis and midges should be important almost every day too. On this little gem of a spring creek, ants have always been a staple, add some beetles and hippie stompers to the box and enjoy the rising fish when it happens. 
Squirrel Jig Minnows, Soccer Moms and Olive Mini Gulps are great streamers. Tungsten Eggs, Tungsten Zebra Midges, 2 Bit Hookers, Tungsten Micro Mayflies and Olive Perdigons will be good choices to add to your 6x Fluorocarbon tippet.
