Weekly AI Outlook as of 06/05/26
Spearfish Creek is running 48 cfs with a brutal heat wave approaching — Saturday's 97°F high will stress the fishery hard. The canyon's shaded pools will be critical refugia as water temps spike. Caddis are in peak season with evening emergences your best bet, but focus on dawn and dusk windows to avoid midday heat stress. Early mornings before the sun hits the canyon floor offer the most comfortable conditions for both fish and angler.
- Flow: 48 cfs — good wadeable level, but canyon shade becomes critical as air temps soar to 97°F Saturday
- Hatches: Peak caddis season with evening emergences. Elk Hair #14 and Stimulators during heat. BWOs midday if temps moderate
- Water Temp: Canyon walls provide shade but 97°F Saturday will push water temps. Target deeper, shaded pools midday
- Best Window: Early morning (6-9am) before canyon heats up, then evening caddis hatch after 7pm when temps drop

Spearfish Creek flows through the dramatic Spearfish Canyon in the Black Hills of South Dakota — a 22-mile limestone canyon with sheer 1,000-foot walls of white and pink limestone through which the crystal-clear spring-influenced creek flows. The canyon is one of the most visually spectacular settings for fly fishing anywhere in the northern Great Plains. Wild brown and rainbow trout are abundant throughout the canyon section. The combination of dramatic scenery, accessible wading, and consistent dry fly hatches make Spearfish Creek worth visiting for any angler passing through the Black Hills.
Spearfish Canyon was used as a filming location for the 1990 movie 'Dances with Wolves' — the canyon's dramatic limestone walls, waterfalls, and clear creek are among the most cinematic natural settings in the Great Plains.
January Outlook
Spearfish Creek in the Black Hills of South Dakota offers surprising winter fishing in a spectacular limestone canyon. Wild brown and rainbow trout hold in the deeper pools and remain catchable during mild spells between cold fronts.
Productive Patterns
- Zebra Midge
- RS2
- Mysis Shrimp
- San Juan Worm
Tips
Winter on Spearfish Creek requires picking mild days between winter storms. The canyon walls provide some shelter from wind. The spring-influenced flows rarely freeze completely. Midday fishing is most productive when temperatures are above 35°F.
Water Notes
Spring-fed flows 40–150 cfs. Water 38–45°F. Rarely ices over thanks to limestone springs. Black Hills roads can be hazardous after snowfall.
February Outlook
February brings the occasional warm spell that can trigger early midge and even small BWO activity on Spearfish Creek. The canyon is often snow-covered and stunningly beautiful. Brown trout hold in the warmest spring seeps.
Productive Patterns
- Zebra Midge
- WD-40
- RS2
- Soft Hackle Midge
Tips
Pick days when temperatures climb above 40°F and overcast skies hold. The limestone canyon section from Savoy to the mouth is most productive in winter. Look for trout stacked in pools below spring inputs where water is a degree or two warmer.
Water Notes
40–120 cfs. Water 40–46°F. Stable limestone-influenced flows. Check road conditions before driving into the canyon.
March Outlook
March marks the early stirring of hatches on Spearfish Creek. Early midges and occasional small BWOs emerge on warm afternoons in the canyon. The first rising trout of the year are a welcome sight in this Black Hills gem.
Productive Patterns
- Midge Dry #22-24
- BWO Sparkle Dun
- RS2
- Elk Hair Caddis (small)
Tips
March conditions vary widely — watch for warming trends that bring afternoon hatches. The canyon section below Savoy is most sheltered. Wild browns and rainbows begin moving from winter holding lies to feeding lanes. Fish rise sporadically by late March.
Water Notes
60–200 cfs. Water 42–50°F. Early spring with possible runoff from snowmelt. The creek runs clear most of March.
April Outlook
Spearfish Creek in the Black Hills of South Dakota is one of the Northern Plains' finest wild trout streams. Wild brown and rainbow trout in a limestone canyon setting that looks more like Montana than the Midwest.
Productive Patterns
- Blue Winged Olive

- Soft Hackle
Tips
Spearfish Creek flows through Spearfish Canyon — one of the Black Hills' most scenic areas. The canyon section from Spearfish Canyon Lodge downstream is the prime water. Wild fish in clear limestone-influenced water.
Water Notes
Spring-fed flows 50–300 cfs. Water 46–54°F year-round. Black Hills limestone geology provides excellent thermal stability.

Caddis and Yellow Sally season on Spearfish Creek. The Black Hills canyon setting is one of the Northern Plains' most beautiful fishing environments.
Productive Patterns
- Elk Hair Caddis

Tips
The canyon walls keep water shaded and relatively cool through June. The evening caddis hatch is excellent. Spearfish Canyon Scenic Byway provides easy vehicle access to multiple wade access points.
Water Notes
60–250 cfs. Water 52–60°F. Beautiful Black Hills canyon conditions.
July Outlook
Summer on Spearfish Creek means terrestrials and evening caddis in the canyon. The Black Hills location keeps temperatures more moderate than lowland streams. Wild trout stack in shaded pools and riffles during midday heat.
Productive Patterns
- Elk Hair Caddis
- Hopper
- Ant (foam)
- Yellow Sally
Tips
Fish early mornings and evenings in July. Midday heat pushes trout deep. The canyon section has continuous shade from the walls which helps. Terrestrials like ants and hoppers blown off the canyon walls produce well.
Water Notes
40–150 cfs. Water 58–66°F. Summer low water. Fish the cooler morning hours.
August Outlook
August terrestrial season on Spearfish Creek. Grasshoppers and beetles from the canyon rims bring trout up for big surface takes. The creek is at its summer low but the spring influence keeps temperatures fishable.
Productive Patterns
- Hopper (foam)
- Beetle
- Ant
- Elk Hair Caddis (evening)
Tips
August on Spearfish Creek means terrestrials. Fish near the canyon walls where hoppers and beetles blow off the rim. The evening caddis hatch remains productive. Avoid midday when water temps approach the upper range.
Water Notes
30–120 cfs. Water 60–68°F. Summer low water. Fish mornings and evenings. Spring seeps maintain cool pockets.
September Outlook

Tips
Fall in Spearfish Canyon is one of the Northern Plains' most beautiful experiences. The limestone canyon turns gold and orange. BWO hatches are reliable on overcast afternoons. Brown trout become aggressive before spawning.
Water Notes
50–200 cfs. Cooling 48–56°F. Outstanding fall Black Hills canyon conditions.

October is brown trout season on Spearfish Creek. The spawning-aggression period brings larger fish into the canyon section. BWO hatches continue and the fall foliage peaks in the limestone canyon.
Productive Patterns
- Streamer (olive/black)
- BWO
- Soft Hackle
- Copper John
Tips
Pre-spawn brown trout are aggressive and territorial in October. Fish the deeper pools with streamers in the early morning and late afternoon. BWO hatches on overcast afternoons can bring exceptional dry fly action. This is the best month for big fish.
Water Notes
60–250 cfs. Water 46–54°F. Ideal fall temperatures. The canyon's October colors are spectacular.
November Outlook
November brings the tail end of the brown trout spawn and transitioning to winter nymphing on Spearfish Creek. The canyon is quiet and the fishing can be very good before winter sets in.
Productive Patterns
- Midge Pupa
- Copper John
- Hare's Ear
- Zebra Midge
Tips
November fishing on Spearfish Creek is underrated. Post-spawn brown trout feed aggressively to rebuild energy. Nymphing the deeper pools and runs produces consistent fish. Watch for early snowfall and ice in the canyon.
Water Notes
50–200 cfs. Water 40–48°F. Early winter conditions. Ice formation begins by late November in shaded canyon sections.
December Outlook
December winter fishing on Spearfish Creek for the dedicated angler. The canyon is covered in snow and ice but the spring-influenced flows remain open. Midges and red larvae patterns are the go-to for deep nymphing.
Productive Patterns
- Zebra Midge
- RS2
- Midge Larva (red)
- Soft Hackle Midge
Tips
Dress warmly and pick midday windows on mild days. The canyon section from Spearfish Canyon Lodge to the mouth holds fish year-round. Access is straightforward from Highway 14A. A quiet, beautiful winter experience.
Water Notes
