While most of writing about Los Angeles Countytrout fishing is limited to posts about the San Gabriel River’s East Fork, there are other venues to catch rainbows.
The much smaller West Fork here for example. Fed by a small handful of streamlets from drainages to the west of highway 39 in the Angeles National Forest, as well as a small discharge from Cogswell Dam, the West Fork of the San Gabriel River offers great access, clear cold water and stretches of barbless-hook-only catch and release fishing.
While I’ve seldom caught West Fork trout longer than 12 inches, this stream is a fabulous place to introduce novices to fly fishing, or to merely strap a fly rod and fly wallet on the back of a mountain bike and explore a phenomenal primitive riparian habitat. One word of caution: be sure to pack in enough drinking water to remain well hydrated since there is no drinking water on the near nine mile well marked trail up to Cogswell dam.
Mountain bikes are the best way to explore the West Fork. Park your car near the gate and begin pedaling up the trail. There are several great places to get your line wet, trying to tease native or other rainbows into taking a fly. Most of the West Fork’s best fishing spots begin about five miles up the trail in a series of small rills that flow into sandy bottoms or small rocky ponds. Overgrown streamside brush most often necessitates tight roll casts or side casting. My best results have always been with light five foot tippets and small midge or mosquito pattern flies tied on # 16, 18 or 20 barbless hooks. Because the West Fork is overgrown for much of it’s length, I use a custom six-foot, three-inch, fly rod with a soft tip.
The combination of small flies that match insect patterns, a light tippet and a rod with a soft tip has worked well for me on the West Fork. So have a bicycle, short pants, a mood expressing t-shirt my ancient JC Penney tennis shoes, as well as a packed lunch, two bottles of cold water and the unshakeable belief that you’re will catch a huge trout, this trip.
Alas, while you’re almost certain to get a few hits on your fly, when you manfully rip lips, what you most often catch are little five or six inch dinks. But there are bigger fish here; you just need to keep your eyes open for pools near small water falls, confluences of small year-round inflows, and dark objects darting in and out of the dappled shadows.
Do make sure to load your fly wallet with an assortment of insect patterns on small barbless hooks. The insect hatch on Midspring mornings has to be seen to be believed. So do the trout, jumping for their food from a brain-freezingly cold wild stream.
I’ve always fished the West Fork using barbless hooks and catch and release techniques. Sometimes it works, and sometimes it doesn’t. I always come back with more flies in my wallet than I started with. You find those expensive flies in overhanging branches or deep inside stream side poison oak bushes.
But at the end of any West Fork fishing trip with young novices, there’s always the near seven or eight-mile high speed coast back down the trail, then highway 39 down to Azusa, for a late lunch at Carmens’, La Tolteca or In-N-out, all on Azusa Avenue.—Jim Forbes on 2/07/2007
