The boat ramp at rim is a good one compared to others. From the ramp the first shoal up stream is red bud, make a bee line for the left side, you have plenty of depth. When you get just below the shoal slow to idle speed and crawl up the narrow chute hugging the left bank. Above is red bud hole, if you have two or three units of water you can buzz right up, in lower water there are rock ledges about half way up, you'll need to idle through with a spotter wearing polaroids at the front of the boat guiding you. If you make it that far and like to wade fish and the water is low enough there is a long gravel bar that I can easly spend a half day fishing. The lower and upper ends of the gravel bar are shallow areas where you'll need the spotter again. The next big hole is armstrong, you should be able to buzz right up it to the bottom of the island at round house. To get through round house with a heavy boat you'll need the big water I talked about in an earlier post. But if you tie your boat up there you can walk to the head if the island and wade your way back, the back side of the island is as close to a sure bet you'll ever find if your introducing someone to fly fishing. I can easily occupy an entire day fishing from Round House back to the ramp at Rim. As is always the case on the white when wading do not put your self in a position to not be able to get back to the boat should the water rise.
I know it sounds like a pain having worry about all the hazards but more
times than not it all works out. Just be careful.
