Where SURPLUS CANAL @ SALT LAKE CITY, UT sits.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. Utah Division of Wildlife Resources publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Utah rule: 68°F.

Normal for Nov 5: 105–193 ft³/s (middle half of 83 years of record). Now: 190 ft³/s, normal.
Normal for this date. 190 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 83 years of record (1944–2026): 10th 91, 25th 105, median 133, 75th 193, 90th 652 ft³/s.
Daily means on record for Nov 5: lowest 52 ft³/s, highest 1,560 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Falling over 24 hours: discharge down 35.4%, from 294 to 190 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
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.
