Things are still very chilly around the Lower Madison River with single digit temps. Looks like mid next week there are some slightly better days with temps in the mid 30s. With cold water temps your best bet is nymph fishing in the afternoons.
It's very important to focus your fishing on the slow deep holes as fish are getting lethargic with the cold water temps. Try fishing a red worm dropping to a small dark Perdigon or Midge nymph. Add some split shot above your lead fly to make sure your rig is getting down quickly. Look for the deep blue water on the inside bends and out in the middle.
Conditions are difficult to predict this time of year as it can be calm, here in Bozeman and ripping windy out there. One tool we use is NOAA's Norris Hill weather station. If its's really blowing there, its likley blowing pretty good out on the lower as well - but that isn't always the case as that station is located at the top of Norris Pass. It's worth checking out though so that you can come up with a plan B if it turns out to be too windy once you hit Black's Ford.
