Quote(s) of the Day: That was the best the day ever up here!

Fishing Highlights:

The runoff seems to have begun. Flows were running around 500 today. That does sound extremely high, but there are still some soft seems around the edges. We even fished some dry dropper rigs in them With great success. Rich found the first soft spot today hooking and landing quite a few nice fish. A twenty two inch rainbow took the dropper all. Matt found another soft spot and took many nice fish as well. We just kept moving and finding the slow seems all day. Some of those spots did require a weighted nymph rig. The hits are still a little subtle so set the hook on every bump. Don't be afraid to go with a little heavier tippet in these conditions. You will appreciate it when the fish swim for the current. It is always fun to be on the water with Matt and Rich. Thanks for another fun day. Matt I will see you again tomorrow!

This is some of the best fly fishing in Colorado! Switch to dries and emergers when you see fish suspended just below the surface or actively rising. With the water running fast the fish are clinging to the bottom so be sure and bring lots of split shot and heavily weighted flies. Look for fish holding anywhere there is structure especially eddies and log jams. Fly fishing is good but the water is cold! Be sure and bring a quality pair of waist high waders and studded boots! Late spring temperatures are running high around Denver and the surrounding Western Slope. Get in some time right now before the water begins to blow out! Be careful out there! Here comes the water, even most tail water streams outside of Denver are running dangerously high! Wading is difficult but the fishing is still good. The water is now high enough that you can nymph fish the bigger holes effectively from the bank. A wading staff may be of use during this high water season. South Boulder Creek at Lincoln Hills Fly Fishing Club has been flowing high but deep nymphing rigs using San Juan Worms, Twenty Incher Stones, Girdle Bugs are still producing trophy fish. Lots of water is coming down from the mountains! Fast current, off color water and lots of debris makes seeing your indicator difficult.  Try using a large Thin-a-ma-bobber in a bright color. The large size will keep your flies suspended and the bright color such as orange or red should be easy to see in the raging river!  The fishing is great.  Partly Cloudy skies and 56-59 degree weather. The water temperature was between 36-39 degrees and Stained.
