March is a great time of year to head to the South Platte, everyone and their mother will be fishing but this is because the opportunity to catch a really large trout is at hand. Yesterday, I headed to South Park to fish the famed Dream Stream, primarily because after checking the weather I realized it would probably be the warmest day I’ve ever spent up there in the spring! The weather reports were right, it got a little windy at times but the sun was shining and it was warm and comfortable all day. Some large trout had entered the river from the lake system and the sight fishing was pretty good, we caught a lot of fish in the 15-16″ range and a few larger ones, with several missed opportunities at true trophies in the mid 20″range. Sight fishing with a double nymph rig was the name of the game. Productive nymphs included gray midges, san juan worms, egg patterns, and rubber leg stone fly nymphs.
