Reading Nov 5, 5:00 PM MST · provisional USGS data
No flow here now. USGS stopped publishing discharge at this gauge on Sep 29, 1986; it still reports what is shown. We found no other gauge on the same river that publishes flow.
Water temperature, last 7 days: 168 readings from Oct 29, 6:30 PM MST to Nov 5, 5:00 PM MST; ranging 75.9 to 82.4 °F; latest 80.6 °F.
USGS provisional data may be revised. Source: USGS instantaneous values.

Where 242 LATERAL ABOVE MAIN DRAIN AT AZ-SONORA BOUNDRY sits.
Over 67°F: avoid fishing for trout. Water 80.6°F now; the highest in the last 24 hours was 81.9°F. Arizona Game and Fish: “Avoid fishing when water temperatures are above 67 degrees.” “If the water temperature is above 67 degrees … it is best to fish elsewhere with cooler water temperatures or switch to fishing for a warmwater species.”

Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
Turn Around Don't Drown (National Weather Service)Specific conductance 1,900 µS/cm at Nov 5, 5:00 PM MST; 7-day range 1,700–1,930 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 6:17 PM MST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
