Map of USGS gauge 015765195 and the river around it
Where Big Spring Run near Mylin Corners, PA sits.
Above the preferred range. Water 59.2°F now; the highest in the last 24 hours was 60.6°F. Warmer than the 50 to 60°F the Pennsylvania Fish and Boat Commission gives as preferred for trout, but not over the 70°F at which it asks anglers to take extra care landing them.
PFBC position statement on closing coldwater tributary mouths to angling in summer (2006) (Pennsylvania Fish and Boat Commission)Normal for Nov 5: 1.1–2.1 ft³/s (middle half of 18 years of record). Now: 1.45 ft³/s, normal.
Normal for this date. 1.45 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 18 years of record (2009–2026): 10th 0.69, 25th 1.1, median 1.4, 75th 2.1, 90th 3.3 ft³/s.
Daily means on record for Nov 5: lowest 0.67 ft³/s, highest 9.02 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 (+6.6% 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 59.2°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)Turbidity 5.3 FNU at Nov 5, 9:00 PM EST; 7-day range 3.1–694 FNU
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.
Turbidity and Water (U.S. Geological Survey)Specific conductance 849 µS/cm at Nov 5, 9:00 PM EST; 7-day range 829–906 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.
NWS observed 3.72 ft stage, 1 ft³/s at Nov 5, 8:00 PM EST (NWS gauge MYLP1; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Forecasts are not available. Only observed stages are available for this point.
