The Root river outside of Lanesboro fished well on Monday despite the early morning sub-zero temps. Once again I have ventured into a new realm of fly fishing. Upon exit from the truck yesterday the thermometer read -3 degrees F( what happened to the forecasted 30 degrees)? There was a constant flow of slush spontaneously forming on the rocks on the bottom of the river. This slush would then rise to the the top and float down river making it difficult to get a nymph through the waters surface. Fish were caught during this phase but as the temps rose, “catching” became more productive. Gray Scuds in all sizes and as usual Prince nymphs and Hares Ears all worked well. Eventually it did hit 30 degrees but not until it was time to leave.
