I started off the day on a Class A brook trout stream that has buffering issues. The stream is very close to a dirt road and the water was pouring in from the road and stream embankment because of an earlier snow melt. I didn't catch a thing. I moved to another Non-Class A stream about 2 miles from the other stream and did very well. Stream conditions, geology, etc. are all very similar on both streams with the difference being the second stream is off the road and has better buffering. On a normal day the first stream will out fish the second stream 10-1. Brook trout on freestones are not very picky so I believe this has to be the major contributing factor in this case and may be in many other similar situations.
