Map of USGS gauge 09419800 and the river around it
Where LV WASH BLW LAKE LAS VEGAS NR BOULDER CITY, NV sits, with 5 other gauges on the same river.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Nevada Department of Wildlife uses are 65°F.
Normal for Nov 5: 91–307 ft³/s (middle half of 39 years of record). Now: 318 ft³/s, above normal.
Above normal for this date. 318 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 39 years of record (1970–2026): 10th 66, 25th 91, median 284, 75th 307, 90th 339 ft³/s.
Daily means on record for Nov 5: lowest 54 ft³/s, highest 367 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 (+2.9% 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.
Species list not on file for this gauge. Check the Nevada Department of Wildlife: Nevada fishing and stocking reports · Nevada fishing rules and regulations.
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.

The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 6:54 PM PST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
