What the agencies suggest
During periods of high water, fish move towards the banks to find calmer water and lower velocitiesPennsylvania Fish and Boat Commission
Wading and boating should be avoided if waters are running high and muddy and the streambed is not visiblePennsylvania Fish and Boat Commission
If stream conditions are not favorable, consider fishing at a lakePennsylvania Fish and Boat Commission

Where MAMMOTH CREEK ABV WEST HATCH DITCH, NEAR HATCH, 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 Mammoth Creek: Brook Trout, Brown Trout, Cutthroat Trout/Bonneville, Rainbow Trout.
Source: Fish Utah hotspot waters (DWR fishing finder) (Utah Division of Wildlife Resources).
Normal for Nov 5: 12–23 ft³/s (middle half of 62 years of record). Now: 89.6 ft³/s, highest for this date on record.
Highest for this date on record for this date. 89.6 ft³/s is above the highest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 62 years of record (1965–2026): 10th 7.7, 25th 12, median 17, 75th 23, 90th 31 ft³/s.
Daily means on record for Nov 5: lowest 3.5 ft³/s, highest 53.8 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 (−9.7% 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.
Flow above the record for this date. Higher than any daily mean USGS has recorded on this date at this gauge. Expect much higher, faster water than usual for the season.
