Which hatches should a working fly box cover on the McCloud through the season?
The McCloud and the Upper Sacramento reward a plan built around three things: which insects are actually on the water, how you fish broken water with a nymph rig, and what flow, clarity and temperature do to your schedule. A working box for the McCloud covers a stonefly, a mayfly and a caddis in a few sizes, and a trip from Dunsmuir runs two or three days with one river per day and a weather window kept open. A working box is not a catalogue. It is a small set of patterns that covers the gaps between one emergence and the next, because on a bouldery river you often fish the hour before and after a hatch rather than the hatch itself. Start with stoneflies. They matter early and they matter in size. Golden stone and salmonfly patterns in sizes 8 to 12 cover the spring period, and a smaller yellow sally in 14 to 16 stays useful into summer. Stonefly nymphs in the same sizes fish under an indicator when nothing is rising. Mayflies come next. A blue-winged olive in 16 to 18 is the pattern that keeps producing when the weather turns grey, and it is the one box section worth doubling. Pale morning duns in 14 to 16 cover the brighter mornings. A small mahogany dun in 14 to 16 handles the later part of the season. Caddis fill the evenings. An elk hair caddis in 14 to 16 and a tan or green larva in 14 to 16 will cover most of what you see on the surface and most of what you do not. Add a couple of small midges in 18 to 20 for cold, slow mornings. That is roughly four rows of a box. The point is not variety. The point is that every pattern in the box has a month where it is the first thing you tie on. The McCloud hatches month by month are covered in more detail at McCloud hatches month by month, including which emergences line up with which stretches.
How do you fish broken water and current seams with a nymph rig?
Broken water is where a nymph rig earns its place, and it is also where most anglers fish too long a line. The pocket behind a boulder is short. The seam beside it is narrow. A rig that lands three feet past the seam has already missed the fish. Set the rig short. Nine to twelve feet from indicator to point fly is a reasonable starting length on the McCloud, and you shorten it in shallow pocket water. Two nymphs, one weighted, one smaller and unweighted, covers the depth range without adding a third fly that tangles on every cast. Fish the seam, not the white water. The foam line is the edge. Trout sit on the soft side of it, facing upstream, and the current delivers food to them without effort. Cast above the seam and let the rig drift down the soft side. Mend immediately, because the faster water on the other side of the seam will pull your line and drag the flies before they reach the fish. Read the water in three passes. First, find the boulders that break the surface. Second, find the seams those boulders create, which are the darker, smoother lanes beside the white water. Third, find the tailouts, where the riffle flattens into a run. Fish the boulders first, the seams second, the tailouts last. Keep the drift short and repeat it. In pocket water you are not making long presentations, you are making many short ones. Two or three casts per pocket, then move. A step and a half between pockets covers more water than a longer cast. Watch the indicator, not the fly. In broken water the indicator does things the fly cannot show you. A pause, a slight dip, a sideways twitch. Set on any of them. In fast water a trout has a fraction of a second to take, and a slow hook set misses most of those fish.
How do flow, clarity and water temperature shape a trip plan from Dunsmuir?
Flow decides where you can wade. Clarity decides whether the fish see you first. Temperature decides whether the fish are feeding at all. All three change through the season, and all three are worth checking before you leave Dunsmuir. High flow pushes fish to the edges. When the McCloud is running high, the productive water is close to the bank, in the soft pockets that the main current does not scour. Wade shallow, fish close, and skip the middle of the river. Low flow does the opposite. Fish move into the deeper runs and the shaded pockets, and they become spookier because the water is clear and shallow. Clarity is the simplest of the three to read. If you can see the bottom in three feet of water, the fish can see you. Stay low, wear dull colours, and approach from downstream where the current carries your scent away. If the water is off colour, you can wade closer and fish heavier tippet, because the fish have less warning. Temperature is the one that should change your plan, not just your rig. Trout feed best in the range that keeps them comfortable, and they slow down when the water gets warm. On a hot afternoon in midsummer, the honest move is to fish early, take the middle of the day off, and come back for the last two hours of light. That is a better plan than fishing through the heat and wondering why nothing moves. A two or three day trip from Dunsmuir fits this pattern well. Day one, fish the Upper Sacramento close to town, which keeps the drive short while you check conditions. Day two, drive to the McCloud and fish the bouldery water with a nymph rig. Day three, if you have it, pick whichever river fished better and go back to the stretch you liked, rather than trying to cover new ground. Camping and access are part of the plan, not an afterthought. Dunsmuir sits between the two rivers, which makes it a practical base. Regulations vary by stretch, so check the rules for the section you intend to fish before you rig up, particularly on the McCloud where special rules apply in places. Carry a thermometer. It costs little and it tells you more about the day than the air temperature does.
What should a two or three day trip from Dunsmuir actually look like?
Keep the days separate. One river per day, one stretch per day, and a start before the light is fully on the water. Mornings are for the surface and the seams. Afternoons are for nymphing the broken water, or for resting the river if the temperature climbs. Pack for the river, not for the forecast. Wading staff, because the boulders are slick. Layers, because the canyon holds cold air longer than the town does. A small box, because a large one slows you down at the water’s edge. Two spools of tippet, one light and one heavy, because clarity changes what you can get away with. Leave the last hour of the day for the tailout below camp. It is often the most reliable water on the trip, and it is the one stretch you can fish without driving anywhere.
What do you check before you leave town?
Three things. Flow, clarity and temperature, in that order. Flow tells you where to wade. Clarity tells you how close you can get. Temperature tells you when to fish. If any of the three is wrong for your plan, change the plan rather than the rig. A trip built this way is not complicated. It is a small box, a short nymph rig, a thermometer, and two rivers within reach of one town. That is enough for two or three days on the McCloud and the Upper Sacramento.
