My parents live on Holter, so I've fished that section of the Missouri a bit. Personally I don't care for it. It's big smelly water and full of people and...*looks around nervously*...wooorrrrm fishermen. Big smart trout though. Caught an amazing rainbow on a midge with 7x tippet there once, major FUN! A boat is most recommended. When they open up that damn dam the water can get huge.

Right there in the canyon though is *****ly Pear Creek, which has some pretty suprising browns in it. There's several miles of access around Wolf Creek (the town).
