Should I go fishing?

Check the water temperature first.

Water temperature is unconfirmed. Use a stream thermometer; stop trout fishing at 70°F or warmer, or sooner if fish show stress.

Why this recommendation?

USGS shows 29 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1993-2025, 15 readings) show a typical middle range of 26 cfs to 43 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.

If you go

Check first
Use USGS 04080798 for live flow near Nelsonville.
Try
Use the Nelsonville hydrograph to avoid arriving on a rising stream.
Leave when
Skip or change the plan when the hydrograph is rising, recent rain has muddied the creek, summer water is warm, the intended bank is not clearly public, or pressure is stacked on one small reach.

Methods, fish species and trip notes

How to fish Tomorrow River today.

Stable flows and cool weather are the best combination. Summer can fish well early, but temperature and low water should decide whether to handle trout.

Normal clear flow

Use dries, dry-droppers, scuds, and small nymphs.

Slight stain

Fish small streamers tight to banks after flow starts falling.

High or muddy

Skip small-stream wading and wait for safer conditions.

Low summer flow

Use stealth, small flies, and temperature checks.

Wading, bank fishing or floating?
Access choicesNo single best option

Wading and Bank fishing have the same top score. Use current access, footing, weather, and local rules to choose.

Wading92/100

Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

Bank fishing92/100

Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.

FloatingNot recommended

This report does not recommend floating this reach.

Full river report

Is Tomorrow River worth the trip today? Check flow, weather, hatches, access, and rules for Wisconsin before you go.

The Tomorrow River is a central Wisconsin trout stream where the Nelsonville gauge is useful, but rules and access still need reach-by-reach checks. Treat it as a small, clear-water report.

Fishing words used on this page
U.S. Geological Survey (USGS) gauge
A USGS gauge is an official river station that measures flow or water height.
Cubic feet per second (cfs)
Cubic feet per second, or cfs, shows how much water passes the gauge each second.
Nymph
A nymph is a young water insect. Anglers also use the word for a fly that copies it.
Blue-winged olive (BWO)
Blue-winged olives, or BWOs, are small mayflies that often hatch in cool or cloudy weather.
Caddis
Caddis are small water insects. The adults look a little like tiny moths.
Emerger
An emerger copies an insect as it rises from below the water toward the surface.
Midge
Midges are tiny flies and a common trout food, especially in cold water.
Scud or cressbug
Scuds look like tiny freshwater shrimp. Cressbugs are small bugs that crawl along the river bottom.
Soft hackle
A soft-hackle fly has moving fibers that can look like an insect rising through the water.
Stained water
Stained water is darker or cloudier after rain, runoff, or a change in flow.

Trip notes

Check these before you choose a reach.

Best flows

Use RiverReports and USGS 04080798 near Nelsonville for the live trend. Stable clear water is best for dries and nymphs. Falling stained water can support small streamers.

When to leave

Skip or change the plan when the hydrograph is rising, recent rain has muddied the creek, summer water is warm, the intended bank is not clearly public, or pressure is stacked on one small reach.

Local plan

Start with trout rules and maps, check the Nelsonville flow, recent rain, weather, and water temperature, then choose one signed access and one backup water before picking flies.

Backup water

If the Tomorrow is high, warm, crowded, or access-limited, compare Black Earth Creek, West Fork Kickapoo River, or Wisconsin River before forcing the same reach.

Before you go

Check Wisconsin trout rules and DNR maps before fishing the Tomorrow River. Exact reach classifications, season dates, and harvest rules should be verified before each trip.

Where to access the river

Nelsonville gauge area

Core flow and condition reference for this report.

Amherst-area road crossings

Useful orientation. Verify public access before entering.

Hartman Creek State Park context

Nearby public-land and fishing planning source, not a substitute for trout-map checks.

  • Public land near the watershed does not make every streambank public.
  • Small streams are easy to overpressure. Rotate water and give pools time.
  • Use DNR maps for exact trout classifications and boundaries.

If this water does not fit the day, check another report before you start the drive.

Trip guidance checked

What was checked: This report is maintained from current regulation, access, flow, weather, and public planning sources so anglers can make better trip decisions than a raw gauge or generic overview would allow.

Live measurements and forecasts keep their provider timestamps. Rules, access, and trip guidance use the source-review date shown here. BlueStreamFly planning advice is editorial interpretation, not an agency notice.

First-hand experience: BlueStreamFly does not claim a first-hand visit or local field test for this report unless a real contributor is explicitly named and linked.
