Before You Go

Know the reach you plan to fish, check the day’s weather, flow, and water temperature, and save what you will need beyond cell service.

First-decision path

Start by watching the water.

Watch where trout are feeding and choose Surface, Film, or Subsurface. Adjust Presentation → Depth → Weight → Change Fly. When changing the fly, refine Size → Shape → Color.

30

Surface flies

Choose Surface when trout are clearly taking insects from the top of the water. Match the size you see before changing shape or color.

12

Film flies

Choose Film when trout are feeding in or just under the surface. Look for bulges, backs, and splashy rises.

36

Subsurface flies

Choose Subsurface when the surface is quiet. Improve presentation, then depth and weight, before changing the fly.

Regional signature: Faster-water coverage, more subsurface depth, compact crayfish, stonefly/search nymphs, two Woolly Bugger colors, sculpin, and dace profile.

Read the river

Let surface texture reveal the run.

Real field photography shows the water as it actually appears. The illustrated guides make speed, depth, seams, cover, and approach easier to name.

1
Scan speed and depth

Watch texture, color, bubbles, and the way the current carries debris.

2
Find the change

Look for seams, pockets, shade, wood, drop-offs, and softer water beside faster flow.

3
Start close, then expand

Begin with the nearest soft margin, trace the speed change toward the darker center, and use the illustrated Run guide to decide where a controlled drift belongs.

Regional coverage

See what kind of water this box is built for.

Use these descriptions to picture the river, its current, casting room, and common holding water. Open the regional map for individual rivers.

Water familyBox fitWhat the fishing is like
Pigeon RiverCore waterA small-to-medium cold river with riffles, pockets, woody cover, and mixed brook- and brown-trout water. Short accurate casts and controlled drifts fit its quicker reaches.
Black RiverCore waterCold headwaters begin small and wooded, then gradually widen. Expect close casting, shaded pools, woody cover, and a mix of brook- and brown-trout water.
Sturgeon RiverCore waterA fast, lively river with pocket water, broken current, deeper slots, and limited standing room in places. It favors quick line control, weighted subsurface work, and well-placed dries.
Rifle, Thunder Bay coldwater reaches & Hunt CreekStrong fitA useful range from tiny research-stream water to medium coldwater reaches. Fishing shifts from close, precise casts under cover to longer drifts through riffles and runs.

Regional fit: These rivers share a northern coldwater box while keeping distinct current speed, structure, and hatch timing. Upper Au Sable uses its separate river-specific system.

Regional river map

Choose your river and build a starting plan.

Choose your river from the selection box or tap a numbered marker. You will see how the water fishes, how the box fits, typical wading, current temperature and weather, and where to begin.

Map markers provide river-system orientation. Measured water leads the decision. The highlighted seasonal window provides historical context, and the local 24-hour forecast shows the likely warming or cooling direction. Active readings show their station and observation time. Current DNR regulations, verified public access, measured conditions, and posted information guide the trip.

How to use the live checks
1 · Match the legal reachUse the DNR map to match the water name and named boundaries, then confirm the rule for the date.
2 · Read the measurementMatch the station to the planned reach and confirm the observation time and measured parameter. Use the 24-hour weather direction, then confirm the selected reach with a thermometer at the water.
3 · Build the starting planReturn here, observe the feeding level, and choose Surface, Film, or Subsurface before changing the fly; then refine Size → Shape → Color.

Seasonal weighting

Use the season to narrow your attention.

The season points toward the most likely insects and presentations. Current water temperature, weather, and what you see on the river choose the starting point.

WindowWhat to watch and where the box has support
Early seasonHendrickson/dark mayfly, black caddis, general nymph, and stonefly/search roles; expect later timing toward the Tip.
Late spring–summerSulphurs, caddis, Cahills, film activity, faster-water attractor and nymph roles. Use large drake/Hex coverage where the local water confirms it.
SummerTerrestrials, pocket-water dries, caddis, crayfish, and streamers where water temperature and rules support them.
Fall & cold waterSmall mayfly/film roles, Isonychia where present, nymphs, and streamers; confirm seasonal rules and safe access.
