The float section of the Madison starts at Lyons bridge and ends at the Ennis bridge. Fishing has been up and down all spring depending mostly on the weather. Get an overcast calm day with temps at least into the high 40s fishing seems to pretty good. Clear cold and windy, stay home and tie flies. The main show in the float section is still streamers stripped hard off the bank. Black seems to be the most productive for me. Fishing seems to start around noon peaking about 2:00 then dying of around 4:00 or 5:00. Warmest part of the day. Crowds aren't here yet it's nice and lonely out there
