Lower Madison is comming alive temps last week were in the low to middle 70's now they are peaking out in the low 60's. Prime for Browns and rainbows. There have been some free floating moss issues, you need to have a good repitoir of moss removal techniques. There are still some hoppers out which seem to playing pretty well in the afternoon other than that it has bee the usuall array of streamers and nymphs. I like the crawfish looking stuff. Lots of daddy's down there. Fish early and Late to avoid the Bozeman crowd. Tight lines
