191 cfs puts Driftless creeks in prime summer form — crystal clear, cold spring water perfect for selective browns. Peak Sulphur season is firing with size #16-18 mayflies emerging around 7-8pm. Thursday's inch of rain will muddy things temporarily, but these limestone-fed systems clear fast. Focus evening sessions 6-9pm when temps drop and bugs start moving. CDC Sulphur and Comparaduns for the hatch, small nymphs and streamers during midday lulls.
- Flow: 191 cfs — ideal summer levels with gin-clear spring water holding steady temps despite 80°F+ air temps
- Hatches: Peak Sulphur emergence 7-8pm (#16-18 CDC patterns), scattered caddis throughout evening window
- Water Temp: Spring-fed creeks holding 52-56°F — perfect for extended evening sessions even in summer heat
- Best Window: 6-9pm prime time for surface action, avoid midday sun when fish go deep in clear water

About this Water
- Limestone
- Best months: Apr–Oct, peak May–Sept
The Wisconsin portion of the Driftless Area — the unglaciated southwest corner of the state — holds the largest concentration of cold limestone spring creeks in the Midwest. Hundreds of small streams flow through limestone-influenced bedrock, supporting wild brown and brook trout through the Coon Valley, Viroqua, and Westby areas. The fishery is intimate: small water, fine tippets, and selective wild browns. The Driftless was the proving ground for Trout Unlimited's stream-restoration work — many of these streams were degraded by 1950s-era farming and have been brought back through decades of habitat work.
Wisconsin's Driftless region holds over 5,000 miles of designated trout streams — more cold-water trout habitat per square mile than anywhere else in the continental US east of the Rockies.
January Outlook
January in the Wisconsin Driftless Area is winter but the spring creeks never fully freeze — their 46–52°F water keeps flowing year-round. Midge fishing in the limestone spring runs is the winter Driftless experience.
Productive Patterns
- Zebra Midge
- RS2
- Scud
- Soft Hackle Midge
Tips
Winter Driftless spring creeks are a surprisingly productive fishery. Creeks like Timber Coulee, Rush Creek, and Trout Run flow year-round from limestone springs and never ice over completely. Midge pupa in the slow pools produce brown trout in January. The coulee country winter scenery is beautiful.
Water Notes
Spring creek flows 30–150 cfs. Water 46–52°F year-round from limestone springs. Never fully freezes.
February Outlook
February midge fishing on the Driftless spring creeks. The limestone springs keep temperatures constant through the hardest Wisconsin winters. Wild brown trout feed on midges year-round.
Productive Patterns
- Zebra Midge
- Midge Pupa
- Scud
- RS2
Tips
February Driftless fishing is one of the Midwest's best-kept winter secrets. The spring creeks flow clear and cold (but not frozen) regardless of air temperature. Fish the slow limestone spring pools with 6X tippet and small midges. Brown trout are active all year.
Water Notes
30–150 cfs. Water 46–52°F — consistent limestone spring temperature. A genuine year-round fishery.
March Outlook
March brings early Baetis hatches to the Driftless spring creeks. The first dry fly activity of the year as air temperatures moderate while the spring creek water stays constant.
Productive Patterns
- Blue Winged Olive
- Baetis Nymph
- Elk Hair Caddis (small)
- RS2
Tips
March is the beginning of the dry fly season in the Driftless. Baetis activity begins on warm afternoons. The coulee country spring creeks are beautiful in early spring with farmsteads and bluffs framing the meadow streams. Fish the slow glassy sections.
Water Notes
30–200 cfs. Water 46–52°F. First dry fly activity of the year. Limestone spring consistency.
April Outlook
The Driftless Area of SW Wisconsin offers excellent early spring trout fishing in spring creeks and limestone streams. Some of the best small stream fishing in America.
Productive Patterns
- Blue Winged Olive
- Elk Hair Caddis
- Pheasant Tail
- Soft Hackle
Tips
The Driftless Area spring creeks run cold and clear year-round. Early spring is excellent for Baetis activity. Fish the famous Timber Coulee or Rush Creek for a classic Driftless experience.
Water Notes
Spring creek flows 30–200 cfs. Water 46–52°F year-round — spring-fed. The Driftless Area has hundreds of miles of quality spring creek trout habitat.
May Outlook
Hendrickson and Sulphur hatches produce excellent dry fly action. The Driftless Area spring creeks at their finest.
Productive Patterns
- Hendrickson
- Sulphur Sparkle Dun
- Elk Hair Caddis
- BWO
Tips
The Driftless spring creeks are world-class fisheries hiding in plain sight in Wisconsin's coulee country. Fish are selective but the setting is beautiful and uncrowded.
Water Notes
30–200 cfs. Water 48–56°F. Perfect spring conditions on limestone spring creeks.
June Outlook
Sulphur and Caddis season on the Driftless spring creeks. Excellent evening hatches throughout the region.
Productive Patterns
- Sulphur Dry
- Elk Hair Caddis
- PMD
- Green Drake
Tips
The Driftless summer hatches are excellent. Fish the evening periods from 6–9pm for the most consistent surface activity. The spring-fed creeks stay cool even in summer heat.
Water Notes
30–200 cfs. Water 50–58°F. Spring-fed coolness — one of the Midwest's most heat-tolerant fisheries.
July Outlook
July summer fishing on Driftless spring creeks is excellent in the morning and evening. The constant 50–58°F spring-fed temperatures keep fish active despite summer air heat. Caddis and terrestrials.
Productive Patterns
- Elk Hair Caddis
- Hopper
- Beetle
- PMD Cripple
Tips
July Driftless fishing is best in the first two hours of light and the evening. Fish the limestone spring pools and seams with terrestrials. The small, intimate coulee streams are easier to fish in summer — wade carefully on the rich algae-covered limestone streambed.
Water Notes
30–150 cfs. Water 50–58°F. Consistent spring temperatures provide summer thermal refuge.
August Outlook
August on Driftless spring creeks mirrors July — cool, spring-fed water provides excellent summer fishing while surrounding streams bake. Caddis evenings and terrestrials all day.
Productive Patterns
- Hopper
- Elk Hair Caddis
- Beetle
- Ant
Tips
August is excellent on the Driftless spring creeks precisely because the surrounding Midwest is experiencing its most oppressive heat. The limestone springs maintain 50–58°F water temperature making this a true thermal refuge. Evening sessions on Timber Coulee are outstanding.
Water Notes
30–150 cfs. Water 50–58°F. Thermal refuge in the summer. One of Wisconsin's finest summer fisheries.

- Egg Pattern
- Soft Hackle
- BWO
Tips
October is the Driftless Area's finest month. Brown trout in full spawning colors are aggressive. The limestone spring creeks maintain constant flow through fall and into winter. A multiple-day exploration of the Coulee country is recommended.
Water Notes
30–150 cfs. Water 48–56°F. Brown trout spawning season. Wisconsin fall foliage peak.
November Outlook

Productive Patterns
- Midge Nymph
- Scud
- Soft Hackle
- BWO (late)
Tips
November Driftless fishing transitions from spawning season to winter midge fishing. The spring creek water stays constant. Fish the deeper limestone pools with midge pupa. The coulee country in late November is quiet and beautiful.
Water Notes
30–150 cfs. Water 46–52°F. Limestone spring consistency. Good late-season fishing.
December Outlook
December on the Driftless spring creeks — the limestone springs flow year-round and the brown trout are active in the cold, clear water. Winter midge fishing at its finest in Wisconsin.
Productive Patterns
- Zebra Midge
- Scud
- RS2
- Soft Hackle Midge
Tips
December Driftless fishing is one of the Midwest's finest winter experiences. The spring creeks never freeze and the fish are feeding. Dress warmly — the coulee country winters are cold. But the fishing is genuinely excellent for those willing to brave the conditions.
Water Notes
30–150 cfs. Water 46–52°F year-round. Genuine December fishing. Wisconsin winter.
