Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Dipnetting for sockeye salmon in the Copper River at Chitina, Alaska

By Troutnut on August 11th, 2011
One of the perks of being an Alaska resident is that we can partake in several "personal use" fisheries that allow dip-netting for salmon. With harvest limits of up to 40 fish, they make it possible to have salmon as a staple of our diets, which we could never do by sport angling because of the 3-fish possession limit and the 10-hour round trip drive required to reach a decent salmon stream from Fairbanks. The crown jewel of Alaska's dipnetting sites is the sockeye salmon fishery at in the Copper River at Chitina. The salmon passing through here are very possibly the best-tasting fish in the world. Fed on plankton in the clean waters of Prince William Sound and the Gulf of Alaska, they stockpile unusually large amounts of tasty, healthy fatty acids in their firm, red flesh. The longer a salmon has to travel to reach its spawning grounds, the more fat it stores, so the tastiest salmon are those caught near the beginning of a journey up a very long river like the Copper or the Yukon.

Although "sporting" is the wrong word for dip-netting, it's much more challenging than most would expect. When I first heard about it, I pictured relaxed Alaskans standing on the bank of a clear, mid-sized river, nets laying on the ground as they watch and wait for salmon to appear. I had not imagined the thundering slurry of powdered mountain that is the Copper River at Chitina, a river the size of the Missouri squeezing through a bedrock canyon 100 meters wide. Most of the water is glacial melt, no clearer than chocolate milk, so densely is it loaded with the dust of the Alaska Range and the Wrangell Mountains. There's no outward sign of the thousands--sometimes tens of thousands--of salmon that pass through every day of the summer, inches below the opaque surface. The dip-netter perches on a narrow shelf of jagged rocks, holding a large net in the river continuously, fighting the force of the silt-laden current from the other end of a 15-foot metal pole. The telltale bump of a salmon in the net may come every few minutes, or hours apart, and I have spent about 12 hours on the net each year to obtain my limit. It's hard work to fill the freezer with this world-class delicacy.

Catch & release purists need not cringe at the sight of these photos: the Copper River sockeye salmon fishery is a sustainably managed, hatchery-supplemented fishery with limits and closures adjusted several times throughout the season by the Alaska Department of Fish & Game. The run each year contains more than enough salmon to replenish the population, especially with the hatchery's help, and the excess is split among commercial fishermen in Prince William Sound, native subsistence users who can each catch hundreds of salmon in their fish wheels, dip-netters in the "personal use" fishery, and a comparatively tiny harvest by sport anglers in clearer tributaries, mostly the Gulkana and Klutina rivers. Many of the fish we dipnet in the main stem Copper are destined for off-road tributaries that rarely see an angler, especially not a salmon angler. When someone fishes that far out into this part of the wilderness, they're in pursuit of grayling, dollies, or rainbows, not salmon.

Here's part of my final catch, though many more fish are hidden in the turbid glacial water.  There are 40 salmon in all.  The limit for a household dipnetting permit is normally 30, but this year the sockeye run greatly exceeded expectations, so the Alaska Department of Fish & Game increased everyone's limit by 10 for several weeks.
Dipnetting to fill the freezer with salmon is not as tidy as catch & release fly fishing.  Here's the process:  1.  Beat the salmon as hard as you can between the eyes with a club, several times if needed, while it's still in the net.  This makes it stop flopping so you can remove it from the net.  2.  Cut the base of the gill arches on one side with scissors, severing major arteries that send blood spurting out of the unconscious fish's body, quickly killing it and assuring ideal flavor.  3.  Thread the stringer in through one of the gills and out the mouth, and stick the fish back in the glacial river to keep cool.  

After whacking ten or fifteen fish in the same spot, the riverbank looks like it warrants a CSI team.

I was at a popular spot for dipnetting, and this little rodent (a vole, I think?) hit the jackpot with an earlier angler's leftover snack.

The Copper River is often over a mile wide, but the dipnetting almost all takes place in this narrow canyon below the confluence with the Chitina River.  Here the river squeezes into a deep, fast, turbulent rapids that funnels fish through a narrow area and forces them to hug the banks where anglers can reach them.

I spent twelve hours holding this net in the river, often in fast current.  The key is to hold it in an eddy, so it billows out upstream and can catch the salmon that are all swimming in that direction.  The eddies along the bank attract salmon because it's easier for them to run upstream with the current than against it.  The best eddies are the narrow ones where the rest of the river is flowing fast downstream most of the salmon hug the bank.

Male Tricorythodes (Leptohyphidae) (Trico) Mayfly Spinner from the Touchet River in Washington
I collected these males about 9:30 AM, air temp. about 68 degrees F. The males were flying about 3 ft above the stream flying up and down the stream rather than the typical vertical swarm you see with most mayfly males. The males are black and the females are a green color due to the eggs they are carrying. They do not live very long which is typical for small bodied mayflies. They do not fly during windy conditions. I suspect these are Tricorythodes minutus.

Driving down the Richardson to Chitina, with a stop at the Gulkana

By Troutnut on August 10th, 2011
I had good photo weather for the 7-hour drive from Fairbanks down to Chitina for the dip-netting trip detailed in the August 12th update. I stopped for a few hours at the upper Gulkana River along the way, hoping to catch grayling in a promising new spot I'd found (but not fished) on an earlier trip. That stretch of river is so enchanting one could spend a lifetime on a single mile of it and never want to leave. I was amazed to find no sign of grayling, except for another angler who said the spot fishes well earlier in the summer. I fished behind spawning sockeye salmon and caught only a round whitefish, and was treated to the sight of caribou crossing the river upstream. I think the spawning salmon have something to do with the lack of grayling, no doubt an interesting story I have yet to figure out.

I like this one.  Glacial river, taiga, tundra, and the perpetual ice cover of a massive high ridge dozens of miles away in the Wrangell Mountains.

Here's a panorama of the Wrangell Mountains, viewed from a pullout overlooking Willow Lake along the Richardson Highway near Glennallen, Alaska.  A day this clear is rare, and the view is spectacular.  You have to view it full-sized to begin to appreciate what it's like scanning this range with binoculars.

While I was taking pictures of the whitefish I caught, I heard loud splashing in the water upstream.  Two caribou cows and their calves were crossing the river.  (Only one calf is visible here.)

At this time of year, sockeye salmon in full spawning colors dot the edges of the upper Gulkana, and are visible from the road in a few places, including this one.

This is the home base for the Chitina dipnetting fishery that supplies thousands of Alaskans with much (if not most) of their annual protein.  Many people pay a jetboat charter to ferry them down to prime spots in the canyon, and ferry their hundreds of pounds of fish back up.  Others follow the trail to which this bridge leads and negotiate the steep canyon wall themselves, with their fish, and haul them back with the help of an ATV.

This is the delta where O'Brien Creek flows out into the Copper River's channel.  It may be one of the most intense graveyards for filleted salmon in the world.

Pteronarcys californica (Pteronarcyidae) (Giant Salmonfly) Stonefly Nymph from the Touchet River in Washington
Here are two size classes of Pteronarcys nymphs. These probably represent two different generations. The largest will probably emerge next spring and the other in two years. There is probably another generation, smaller, I did not collect. In a Canadian study they discovered Pteronarcys eggs do not all hatch simultaneously but hatch for a period of nearly two years, making their egg/nymphal life 5 years. The other photo is of a curled nymph, a typical response to disturbance.

This is a tailed frog, genus Ascaphus that lives in cold fast streams of the west. Perhaps this critter is one reason that leech flies work in some trout streams.

Day float on the Chatanika River

By Troutnut on August 5th, 2011
I headed out with a friend & his canoe to float the Chatanika River. It's a popular river to float, so naturally it wouldn't be adventurous unless we decided to do something crazy, like float dozens of miles upstream from where people usually put in. We had some fine dragging and even a little bit of paddling, and many remote pools held eager grayling that rarely see a fly.

This simple rubber-legged foam beetle is one of my favorite flies for Arctic grayling.  It's quick to tie so I don't mind losing one or two on snags.  It's durable, so one fly can last a hundred fish or more.  It never needs floatant to ride the surface well.  Most importantly, it catches fish, although grayling often hit almost anything.  The bold profile and attention-grabbing plop of the beetle, I think, draw fish from farther away than a more subtle fly might, and it often draws unusually savage strikes.
