Catoctin Creek is a freestone river in Maryland.
Pick one of its USGS gauges and hear from us when the flow moves into or out of its usual range for the date, or crosses a flow you set. We check the public USGS reading every 2 hours and email only when it crosses, at most once every 6 hours. Flow alone is not a fishing forecast or a safety call.
Signed in: one step. Otherwise we email a confirmation link first. Every alert has one-click links to stop it.
Start from the agency's public access map. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Seasons, limits, special regulations and closures for each reach are on the agency pages below. Read them before you go.
Each comes from the agency's own published list; where the list names a reach it is quoted. A designation applies to the listed reach, not necessarily the whole water. Listed in the finder under trout.
On the Delayed Harvest Trout Fishing Areas (Group I and II) list (Maryland Department of Natural Resources (Maryland Fishing Guide, eRegulations edition), read 2026-10-20). All waters with this designation
Measured from the NHDPlus High Resolution (flowlines and waterbodies) (U.S. Geological Survey, read 2026-11-04) for this water’s own mapped feature. Rounded figures; they describe the channel, not today’s conditions.
Areas the Protected Areas Database of the United States (PAD-US), public access (U.S. Geological Survey, Gap Analysis Project, read 2026-11-05) lists as owned or held in easement and open to the public, crossed by the mapped channel. Boundaries are mapped, not surveyed. Nothing on this page grants or implies access: check the agency map, posted signs and landowner permission before you fish.

Normal for Nov 5: 8.1–49 ft³/s (middle half of 79 years of record). Now: 8.86 ft³/s, normal.
Normal for this date. 8.86 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 79 years of record (1948–2026): 10th 5.1, 25th 8.1, median 18, 75th 49, 90th 90 ft³/s.
Daily means on record for Nov 5: lowest 3.2 ft³/s, highest 842 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).
Rising over 24 hours: discharge up 16.3%, from 7.62 to 8.86 ft³/s. 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.
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 1.56 ft stage, 9 ft³/s at Nov 5, 9:45 PM EST (NWS gauge MDLM2; its stage datum can differ from the USGS gauge height).
Forecasts are issued routinely year-round.

No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Maryland DNR uses are 65°F and 68°F.
This gauge is on our page for Catoctin Creek, but no agency page we read lists its species.
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)Rising water. Rising over the last 24 hours (discharge up 16.3%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
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.
