Ogden River and Weber River – The Ogden River is still fishing pretty hot but the water is very low. Most productive patterns are egg and very small midges. The Ogden browns love the black zebra midge so have a handful with you just in case you get caught up in the pesky over hanging trees. Keep your distance and stay behind the fish as they spook very easily. Also watch for redds and make a good quick release. The low water should help with that. The lower Weber River from Echo down to Ogden is fluctuating in flows. The lower Weber is showing signs of good fishing with streamers and regular fall/winter patterns but because of the flows it depends on how high the river is. Above Coalville fishing is was hot but now is tapering off as the colder temps settle in. Streamers, egg patterns, and midges are all doing well also be mindful of private property.
Green River – Fly Fisherman I hear are doing well with big terrestrial (grasshoppers, beetles and black ants) and using drop like a tungsten bead midge, scuds, shrimp patterns and egg. Always remember fish a lot of times are attracted to those big terrestrials and then hit your smaller fly. Streamers have been reports as fair success especially on the those overcast days and low light. Tyler Skeen from Fish Gear floated the A section last week and reported much of the same activity. The colder temps have affected it a bit and slowed down the fish but there are still some nice fish waiting to slam your streamer of eat that dropper.
Provo River – The spawning brown trout have slowed down a bit due to the colder weather like most browns around the state. The fish are still going after bigger streamers with dark colors and flash. This time of year through march it is important you pack a ton of smaller flies 18′s to 24′s. You will still probably have the best success using the staple flies, hare’s ears, scuds, pheasant tails and midges. It also isn’t a bad idea to still use an egg pattern and or san juan worms to mix it, you can still find those late spawners that are being aggressive. For the middle section much of the same applies. I have heard reports of still some dry fly action and the key is going small. Remember those dry fly days are very dependent on the weather and the surface water temps. Something to also consider is harvesting a few fish once and awhile. The DWR encourage harvesting your limit and leagel size fish on the Provo River.
