Map of USGS gauge 16226400 and the river around it
Where N. Halawa Str nr Quar. Stn. at Halawa, Oahu, HI sits, with 1 other gauge on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer. We found no Hawaii agency water-temperature line for trout anglers. The lines below are the National Park Service's, federal guidance, not a Hawaii rule: 68°F.
Species list not on file for this gauge. Check the Hawaii DLNR, Division of Aquatic Resources: Hawaii freshwater fishing · Hawaii fishing regulations.
Normal for Nov 5: 0–3.2 ft³/s (middle half of 24 years of record). Now: 2.84 ft³/s, normal.
Normal for this date. 2.84 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 24 years of record (2002–2026): 10th 0, 25th 0, median 0.07, 75th 3.2, 90th 38 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 87.9 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 40.6%, from 4.78 to 2.84 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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)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)Turbidity 103 FNU at Nov 2, 11:20 AM HST; 7-day range 0–2,960 FNU; more than a day old
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
