Map of USGS gauge 01576381 and the river around it
Where Hammer Creek at Obie Rd nr Schafferstown, PA sits.
Above the preferred range. Water 59°F now; the highest in the last 24 hours was 60.8°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)USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Steady over 24 hours (+3.4% 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°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)Dissolved oxygen 8.7 mg/L at Nov 5, 10:30 PM EST; 7-day range 8.7–13.8 mg/L
Enough oxygen for coldwater fish: 8.7 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.9 at Nov 5, 10:30 PM EST; 7-day range 7.9–8.4
Within EPA's freshwater range: pH 7.9 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 5.2 FNU at Nov 5, 10:30 PM EST; 7-day range 2.9–31.2 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 572 µS/cm at Nov 5, 10:30 PM EST; 7-day range 564–578 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 0.9 ft stage, 12 ft³/s at Nov 5, 9:30 PM EST (NWS gauge HCSP1; 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.

Checked Nov 5, 10:52 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.
