I've flyfished it 4 times, but not in the last 5 years. There are (at least were) native trout (brook and brown?), very small, in the upper catch and release section. The entire south side is paved for 7 miles as a handicapped access stream. A bike is essential. Strap your rod tube to the frame, and ride upstream the mile or two until you reach the c&r section. They plant below it, and the planters took flies as well. My recollection is there's some open spots, but often brushy and tight, riffles, pools, pockets, overhanging branches - lots of fun. In the open spots, I often saw holding fish that I couldn't get to take dry or nymph. 4wt (or under) worked great for me with size 16-20 elk hair caddis. Yellow body was killer. Fisherman's Spot in Van Nuys used to carry them. Don't bother going early in the am, since the canyon walls are deep and it will be shaded till quite late in the morning. I learned the hard way, getting there at 8am and no action till around 9:30 or 10am when the sun hit and the bugs come out.
