Map of USGS gauge 01475510 and the river around it
Where Darby Creek near Darby, PA sits, with 1 other gauge on the same river.
In or under PFBC's preferred range. Water 59.7°F now; the highest in the last 24 hours was 59.9°F. The Pennsylvania Fish and Boat Commission: “The preferred temperature range for trout is between 50 and 60 degrees Fahrenheit.”
PFBC position statement on closing coldwater tributary mouths to angling in summer (2006)Normal for Nov 5: 23–61 ft³/s (middle half of 26 years of record). Now: 32.8 ft³/s, normal.
Normal for this date. 32.8 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 26 years of record (1965–1990): 10th 18, 25th 23, median 38, 75th 61, 90th 135 ft³/s.
Daily means on record for Nov 5: lowest 15 ft³/s, highest 206 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 (+7.9% 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 Pennsylvania Fish and Boat Commission: Pennsylvania adult trout stocking schedule · Pennsylvania fishing regulations.
Cold water. Water 59.7°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 698 µS/cm at Nov 5, 8:00 PM EST; 7-day range 667–700 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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 8:37 PM EST; 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.
