Why this recommendation?
USGS shows 295 cfs. The flow has been falling about 60% over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1898-2025, 128 readings) show a median near 1,200 cfs and the lower quartile near 552 cfs; today's flow is below normal for the date. This is below normal, so edge depth, temperature, and pressure matter.

If you go
- Check first
- Use the Austin and Bastrop USGS gauges to understand release and downstream trend.
- Try
- Start with topwater near shade before the sun gets high.
- Leave when
- 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.

Methods, fish species and trip notes
How to fish Colorado River Below Austin today.
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.

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.
- Caddis
- Caddis are small water insects. The adults look a little like tiny moths.
- Midge
- Midges are tiny flies and a common trout food, especially in cold water.
- River reach
- A reach is one named section of a river or stream.
- 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.
- Streamer
- A streamer is a fly that looks like a small fish, leech, or other swimming food.
- Tailwater
- A tailwater is a river below a dam, where releases can change the flow quickly.
Why this call
Why this score
FlowUse caution
USGS shows 295 cfs. The flow has been falling about 60% over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1898-2025, 128 readings) show a median near 1,200 cfs and the lower quartile near 552 cfs; today's flow is below normal for the date. This is below normal, so edge depth, temperature, and pressure matter.
HeatUse caution
The current NWS air forecast is about 81F, and the next 24-hour high reaches about 103F. This is an air forecast, not a water-temperature reading. This gauge has no live water temperature. Fish early and check the river with a stream thermometer.
Public alertUse caution
A heat alert is active near this forecast point, so the score is capped at caution until water temperature and fish-handling risk are checked. NWS alert: Heat Advisory issued September 12 at 4:18AM CDT until September 12 at 7:00PM CDT by NWS Austin/San Antonio TX.
SeasonHelps
Fall: Cooling water and baitfish movement make streamer fishing more reliable.
Fishing usefulnessHelps
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.
Trip notes
Check these before you choose a reach.
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.
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.
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.
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.
