Map of USGS gauge 01451650 and the river around it
Where Little Lehigh Creek at Tenth St. Br. at Allentown sits, with 2 other gauges on the same river and our water's map point.
In or under PFBC's preferred range. Water 58.3°F now; the highest in the last 24 hours was 58.3°F. The Pennsylvania Fish and Boat Commission: “The preferred temperature range for trout is between 50 and 60 degrees Fahrenheit.”
Normal for Nov 5: 67–120 ft³/s (middle half of 40 years of record). Now: 43.3 ft³/s, much below normal.
Much below normal for this date. 43.3 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 40 years of record (1987–2026): 10th 52, 25th 67, median 76, 75th 120, 90th 208 ft³/s.
Daily means on record for Nov 5: lowest 40 ft³/s, highest 302 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 (+0% 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 the agency lists for Little Lehigh Creek: Brown Trout.
Source: Class A Wild Trout Waters (Pennsylvania Fish and Boat Commission).
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)Cold water. Water 58.3°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (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)Specific conductance 673 µS/cm at Nov 5, 11:45 PM EST; 7-day range 661–679 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 2.34 ft stage, 43 ft³/s at Nov 5, 10:45 PM EST (NWS gauge APAP1; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
