Spring Fly Fishing: Pre Run Off

Spring is an excellent time of year to be fly fishing in Colorado and while the warmer temps can bring higher off color water don’t let it keep you from fishing. Here are a few fly fishing tips that might help you keep the rod bent during pre run off season in Colorado.

Watch the gauge – Generally your highest water levels will be around midnight and start to drop slightly after. The drop will usually continue until the following afternoon when the water will start to come rise again. What you are looking for is consistency. Fish like gradual change not drastic change. If you see a big bump of water chances are you can expect fishing to be a little slow. Give the water some time to level out before heading to the river. You will see these big bumps once we start having warmer weather day after day. This will eventually lead to full on run off. But until then keep an eye on the water gauge and focus your fishing efforts during the drop.

Water Types – Higher water will move some fish around so be sure to fish areas that you may have over looked a month ago. Shallow riffles and pocket water are now holding a lot of fish, these areas can be really productive especially when streamer fishing. Look for rising fish in slower pockets, pools and seam during the warmer parts of the day. Blue Winged Olives and Midges are dominating the hatch scene right now but expect Caddis to make and appearance real soon. On the right days the dry fly fishing can be some of the best all year.

Flies – Bigger water means we can start introducing larger nymphs and streamers. The faster river overturns rocks and old logs pushing Stonefly Nymphs, Caddis Larvae and Sculpins down the river. Streamer fishing can be excellent this time of year, especially in faster water. Black, Olive, Natural, Yellow and White colored streamers are good spring colors to be moving through the all water types. Nymphing can be lights out as well. Pats rubber leg, Prince Nymphs and SJ Worms are excellent attractor flies trailed by smaller mayfly imitations. As the water continues to rise fish will get pushed to the banks so be sure to fish those close pockets before wading into them.

Tippet – Beef up your tippet. Fish are not quite as picky with the off colored water so take advantage of it and bring out the 3x-4x. This will help you put the breaks on fish who get out in the faster water and allow you to pull a little harder when bringing that big rainbow to the net.

Use Your Head – The water gets very dangerous this time of year so whether you are floating our wading keep an eye out for debris floating down the river. Know your limitations and be safe. We often forget how powerful the water can be once it is above your knees, some spots you could cross a month ago are now too deep and taking a swim this time of year could be fatal.
