Map of USGS gauge 10150500 and the river around it
Where SPANISH FORK AT CASTILLA, UT sits and our water's map point.
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.
Species the agency lists for Spanish Fork River: Brown Trout.
From our page for Spanish Fork River, on the same river as this gauge; the agency list is for the water, not this exact reach. Source: Fish Utah hotspot waters (DWR fishing finder) (Utah Division of Wildlife Resources).
Normal for Nov 5: 67–109 ft³/s (middle half of 99 years of record). Now: 85 ft³/s, normal.
Normal for this date. 85 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 99 years of record (1920–2026): 10th 57, 25th 67, median 81, 75th 109, 90th 140 ft³/s.
Daily means on record for Nov 5: lowest 29 ft³/s, highest 540 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).
Steady over 24 hours (−4.7% discharge). 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.
