The Green River near Pinedale, WY is fly fishing well! Water temperatures on the lower stretches below the Warren Bridge have finally increased enough to get the fish feeding. Water clarity is at about 3 feet and improving. Guide trips have produced good numbers of browns, including the 23 incher shown below. Nymphs and streamers have been the ticket. Best bugs to use are – #6 Yuk Bugs and Rubberlegs, #12-14 PT’s and Princes, San Juan Worms, JJ’s Specials, Black Leeches, and Olive Sculpins. We did see adult Golden Stones and Yellow Sallies actually on the water, so this means dry fly fishing should crank up in the next few days!
Yellowstone National Park has been the place to be recently! The Firehole River has been lights out through the entire length of river with amazing hatches and consistent dry flyfishing. Baetis, PMD’s, and several species of caddis are all abundant. Yes I said Baetis… Mother Nature is in full effect with lots of rain and a few snow showers. Forecasts are calling for sun and temps in the 70’s this weekend. Bring it! Morning PMD spinner falls, mid-day hatches, and evening egg-laying caddis make this tour a full day event. Job, What job? Watching the evening caddis swarm is mind boggling and a hoot to fish! I enjoy swinging a White Miller soft hackle through this mess and watchin ’em leap! You gotta love Salmonflies! This prehistoric giant of the bug world has been out in the lower Firehole canyon and near the Madison Junction. Water Walkers and Sunken Stones are my go to’s when this is on. Skate these flies across the surface for the most fun. There are reports of a few Gray Drakes as well. Let’s hope this hatch is stronger than in recent memory…. The next three weeks should prove to be great action on these rivers….
A new website designed specifically for Aquatic Invasive Species information in the Greater Yellowstone Ecosystem has been launched! It includes maps of current infected waters in the region and the latest data from recent surveys on local waters plus much more! Greater Yellowstone Area Aquatic Invasive Species
Wyoming is the newest state to implement mandatory invasive species boat stickers for all boats on WY waters. As of May 17,2010, all watercraft over 10 feet in length are required to purchase a sticker. Funds generated by these stickers will pay to educate the public about AIS,and fund prevention efforts to keep AIS from being introduced into Wyoming, such as watercraft inspections, enforcement, and implementation of AIS regulations. The Wyoming legislature also appropriated $1.5 million in general fund monies to fund AIS prevention. Costs are as follows - Motorized watercraft registered in WY - $10 Motorized watercraft registered in another state - $30 Non-motorized watercraft owned by WY resident - $5 Non-motorized watercraft owned by a non-resident - $15 Stickers can be purchased on WGFD website or any automated license selling agent across Wyoming. Stickers are valid until December 31 of the year purchased.
Yesterday I attended the Summit on the Snake, a day-long watershed education conference that provides all river enthusiasts with education that inspires them to care for and connect with the Snake River. One of the hot topics for this year’s event was presentation by doctoral candidate Kris Homel on the Spawning, Distribution, and Movement Patterns of the Snake River Finespotted Cutthroat in the Snake River below Jackson Lake. In 2007 and 2008, Fish the Fly guides participated in the catching and tagging of cutthroat trout for this study. Fish were implanted with radio transmitters and returned to the river. Migratory patterns and spawning habits were then recorded over the past three years. Interesting findings included that one fish moved over 110 km from the Upper Snake to the Greys River! Another fish swam over 45 km during January when most cutthroat were thought to be dormant. Over 57% of tagged fish made spawning migrations while some cutthroat spawn in the river. Stay tuned for more findings from this study…
