Map of USGS gauge 16097500 and the river around it
Where Halaulani Str at alt 400 ft nr Kilauea, Kauai, HI sits.
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: 5.8–15 ft³/s (middle half of 67 years of record). Now: 9.67 ft³/s, normal.
Normal for this date. 9.67 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 67 years of record (1959–2025): 10th 4.4, 25th 5.8, median 8.1, 75th 15, 90th 35 ft³/s.
Daily means on record for Nov 5: lowest 2.9 ft³/s, highest 98 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 16.6%, from 11.6 to 9.67 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.

Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
