Colorado River Below Austin looks very fishable right now.
Current USGS flow is 1,170 cfs. It has risen about 1133% over the past 6 hours. Today's flow is within the normal seasonal range of 592 cfs to 1,920 cfs. Weather, water temperature, and access are the next checks.

Best supported approachBank / edge
Compare wading, bank fishing, and floating before choosing how you will fish.
Bank / edge · Best fit89/100
Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.
Float86/100
A float is in play where this report supports boat access and wind, releases, and shuttle logistics are manageable.
Check before you drive
Current flow and weather.
Look at whether the river is rising or falling, then check wind, rain, and storms. These can change both safety and fishing.

How to fish it
Fish it as a warmwater river, not a trout report.
The Colorado below Austin is a bass and warmwater fly fishing page. Flow, access, heat, and shuttle logistics matter more than a trout-style hatch chart.
- Use the Austin and Bastrop USGS gauges to understand release and downstream trend.
- Poppers and baitfish patterns make the most sense early, late, and around shade.
- Crawfish and hellgrammite-style flies are useful when bright sun pushes fish down.
- Use official TPWD access pages and do not assume private banks are open.
Why the score looks this way
FlowHelps score
USGS shows 1,170 cfs with a rising about 1133% over about 6 hours trend. Today's flow is within the normal seasonal range of 592 cfs to 1,920 cfs. Weather, water temperature, and access are the next checks.
SeasonHelps score
Summer: Early and late topwater can be good; midday heat is often a safety and comfort problem.
WeatherHelps score
The NWS forecast is about 81F with Clear.
Public alertsHelps score
No active NWS alert was returned for this forecast point.
Fishing usefulnessHelps score
Skip or shorten the trip when heat index is unsafe, thunderstorms are building, flows are rising, the shuttle is not confirmed, or the only plan depends on crossing or using private banks.
Read the water
What changes the plan.
The best fly fishing plan is a dawn or evening warmwater session with flow, heat, and access already checked. On hot afternoons, fish shade, deeper outside bends, and current breaks or shift to scouting.
Low clear flow
Use smaller streamers, long casts, and focus on deeper shade and current edges.
Moderate stable flow
Float or wade carefully and cover banks, wood, and gravel transitions.
High or stained water
Avoid unsafe wading and use larger dark streamers from secure positions.
Summer heat
Fish early or late, carry water, and protect fish and yourself from heat stress.
Your trip plan
Know when to go—and when to skip it.
Best flows
Use USGS 08158000 at Austin for the immediate below-city trend and USGS 08159200 at Bastrop for downstream context. Stable or gently moving warmwater flows are easier to fish than sudden release changes, flood pulses, or low hot water.
When to skip
Skip or shorten the trip when heat index is unsafe, thunderstorms are building, flows are rising, the shuttle is not confirmed, or the only plan depends on crossing or using private banks.
Local plan
Start with the Austin gauge, then compare the Bastrop trend and TPWD access pages. Pick one legal access sequence, fish shade and current early, carry water, and keep a shorter bank plan ready if wind or heat makes a float unattractive.
Backup water
If the lower Colorado is too hot, high, muddy, or access-complicated, compare the Guadalupe River, San Marcos River, or Pedernales River before forcing the same warmwater plan.

Fly pattern · report suggests “Clouser”Clouser Deep MinnowThe reviewed chartreuse-and-white form uses sparse layered bucktail with flash around lead barbell eyes. The eyes make the fly sink between strips and ride hook point up; color, eye weight, hook, and saltwater materials must remain labeled.See photos & how to fish it ↗
Fly family · report suggests “crayfish”Crayfish and Crawfish PatternsCrayfish patterns differ in claw size, eye placement, shell profile, leg motion, weighting, hook orientation, and snag resistance. Rust, brown, olive, tan, and pale molting colors remain labeled choices rather than aliases for one recipe.See family guide ↗+ 3 more reviewed guides in the Fly Box June to AugustEarly and late topwater windows, cicadas, hoppers, shad, and bluegill forageFoam popper, slider, deer-hair diver, shad streamer, crawdad
Fly family · report suggests “Foam popper”Bass and Panfish Popper PatternsPoppers may use cupped foam, cork, balsa, deer hair, or pencil-shaped heads. Head face, size, buoyancy, tail, legs, and weed guard determine sound and action; a generic popper label does not identify one fly.See family guide ↗
Fly family · report suggests “slider”Warmwater Slider and Diver PatternsA slider has a tapered, flat, or softly shaped head that glides or pushes a small wake with limited noise. A diver has an angled, collared, folded, or otherwise shaped head that pulls below the surface when stripped and rises on the pause. Frog, baitfish, and large-insect profiles can be tied on either idea, so the exact head action, buoyancy, hook orientation, weed guard, and material must stay named.See family guide ↗+ 3 more reviewed guides in the Fly Box September to NovemberCooling water, shad movement, crayfish, and steady streamer fishingBaitfish streamer, crayfish, hellgrammite, olive bugger, soft hackle
Fly family · report suggests “Baitfish streamer”Baitfish and Minnow PatternsBaitfish and minnow wording does not identify one fly.

Start with topwater near shade before the sun gets high.
02
Switch to baitfish streamers on current edges, bridge shade, wood, and outside bends.
03
Use crawfish and hellgrammite patterns when fish hold close to bottom.
04
Plan floats around official access, takeouts, heat, and wind rather than mileage alone.
05
Do not publish or follow private-bank shortcuts unless access is clearly allowed.
