Little hands gripping a big fish
Fishing slowed a bit this Saturday. Despite some good winds late last week, Pyramid was miserably slow and that seemed to be the consensus for everyone we spoke to. Water is still only 44 degrees; it needs to warm about another 5 degrees for fish to start coming in from the depths. 
This last week I've been working with my my eldest son on his 1st grade science project and what better topic to choose than Entomology...its a great basis for fly fishing. Not only is it educational, its something he really enjoyed (unlike when I take him fly fishing, he's bored if he doesn't have a fish in 5 minutes). This month is a great bug month, especially with the Truckee River flows being so constant...the one good thing about a lousy water year. This may be a bit basic for some of you avid river bums (after all, it was for a 1st grader), but I thought these seine net samples did a good job at showing a typical cross section of the abundant Truckee River invertebrate biomass.
In North America there are over two thousand species; in Britain there are at least 430; while there are over 600 species in mainland Europe; over 200 in Australia; and even more the world over. Where they are found, the midges form at least 50% of the aquatic insect population. In rivers midge can outnumber the 'mayflies' by as many as four times. Since the early part of 20th Century entomologists have gained a detailed understanding of these insects; knowledge which anglers have not ignored. The midge's lifecycle includes a full metamorphosis. Starting as eggs they hatch out as larvae and then have later phases as pupae and then adult." Above is a picture of an adult and a larva; they number in the thousands on any section of water on any given day.
"Commonly known as caddisflies or sedge flies, number well over 7,000 worldwide. There are 1,200 in North America, 900 in Europe, and 640 in Australia. They represent a vast group occupying niches in both still and running water. Their greatest diversity is found in and around running water. Distinguishing the species of adult or larva is very difficult and usually impractical when waterside. This situation is not lost on an angler who will find several species present in significant numbers on any given body of water. Fortunately it is relatively easy to identify a caddisfly as belonging to one of five groups: Net-Spinners, Free-Living Caddis, Tube-Case Caddis, Saddle-Case Caddis, and Purse-Case Caddis. By briefly studying these groups we can later apply fishing strategies to match them." Above are images of a sedge adult and a green sedge larva. Caddis larva are tough to seine net, they hold firm to their homes and are easiest captured by flipping rocks.
The presence of stoneflies in a river or stream has always been a good indicator of a healthy aquatic environment. These members of the insect order Plecoptera are found in cool, well oxygenated flowing waters and occasionally along the wave-swept shoals of northern latitude lakes. Stoneflies have a worldwide distribution and thus are an important fish food source in both the larval (nymphal) and adult stages. Their life cycle which can include as many as 3 years in the larval stage is a significant reason why they are of such interest to fish. The larvae are benthic dwellers, crawling amongst the rock and rubble of the faster moving parts of the stream known as the riffle and run zones. Depending on the species, stonefly larvae can be herbivorous, omnivorous or carnivorous. Smaller aquatic invertebrates such as mayfly nymphs, dipteran larvae, algae and detritus are all common food sources of stonefly larvae." Above are images of stones caught in our seine net, a Skwala nymph, an adult Winter Stonefly and an adult Skwala Stonefly. Find, shallow oxygenated water to find these nymphs, they're great clingers but poor swimmers.
have been up the past couple of weekends to ~545 cfs due to higher flows coming out of the dams at Tahoe and Boca, but still, the water was in great shape. 
For the second part of the qualifier, they do the same on Pyramid Lake. We learned one guy got 600cm in one day on the Truckee, that's 240" between 11 fish for an AVERAGE length of 21.5" per fish! Out for 30 competitors, 6 will move on to the US National Fly Fishing Championships and possibly make the 'Fly Fishing Team USA' World Team. That's the team that would represent the US in the The World Fly Fishing Championships in Bohinjska Bistrica, Slovenia. It was a cool event to observe, though we did have to give way to competitors which were hitting some of our favorite runs...oh well, it was for a good cause.
I cutoff my midge dropper and rigged up a double Skwala rig, hit some faster water and had some luck. I only landed a few smallish bows, but big brownies can't resist this T-Bone of the insect world.
Fellow contributor Dan and I attend the Fly Fishing Film Tour in downtown Reno. What a great event, sweet videos and lots of avid anglers that love fly fishing as much as us. It was a treat to meet many of the moguls of the Reno and Truckee fly fishing scene (including event coordinators Matt Heron and Dave Lass) and catch up with some old pals. This was the first one they've done in Reno and the turnout was excellent. I highly recommend going to next year's event, we'll post it when it comes up.
