Mother’s Day Caddis Hatch

According to social media the Caddis craze is starting to happen here in Colorado. Pictures of oars covered in Adult Caddis, fish with dry flies in their mouths are littering my facebook feed and I love it. Personally I have only seen a few adult Caddis fluttering across the surface of the Eagle River but I know they are on the move. In fact we were catching more fish on our Caddis imitation during a BWO hatch last week then on Blue Wing Imitations, so that must tell us something.

This time of year fly fishing in Colorado can be very very easy. The fish are coming out of their winter lies, bug activity is increasing, water levels are rising and it seems that you can catch a fish everywhere. And with the arrival of the caddis the fishing is only going to get easier. But, do not take it for granted because before too long the aggressive trout of the spring will turn into picky little bastards in July.


Caddis Fly selection this time of year can vary in size but not so much in color. As the water tends to be a bit stained fish tend to key in on the profile of the fly versus its color. Unlike later in the summer, when the difference between hooking fish and getting refused can be just a slight color difference in fly patterns, spring time is a bit more forgiving. Getting your fly pattern into tight spots along the river bank can reward you with some great fish. For this reason, I prefer to cast a single dry during a caddis hatch rather than double dries. This allows me to get my fly tighter to the bank and under trees where caddis tend to fall. I have also found that skating caddis flies along the surface can really entice some aggressive strikes during a Caddis Hatch. This also helps me distinguish my fly amongst other bugs on the water in a heavy hatch. If fish are eating with aggressively I tend to throw Olive PMX and let it ride high on the surface. This fly is one of my go to’s during a caddis feeding frenzy. But, if fish are being a bit more selective the x- caddis is an absolute crusher for picky trout. This fly tends to ride a little lower on the water surface and the small piece of antron on the tail allows the back end of the fly to sink a bit. Sometimes that is all it takes to get that shy fish who wants to slurp in its caddis snack.

Now is the time to be ready when you buddy calls and says “lets got.” Fill that dry box and get ready for some great Spring Dry Fly Fishing in Colorado.
