Access caveats and watch for
Access caveats
- Mattlingy Park is town-managed and historically fee-controlled; verify current operation and access before launch.
- Smallwood is the hard route endpoint before the open Potomac continuation; do not treat Naval Surface Warfare Center or private shorelines as access.
- The Charles County guide is an older official map; current closures and facility conditions supersede it.
Watch for
- USGS 01660795 lower-Potomac proxy and, for Mattawoman, USGS 01658000 same-creek station
- tide, wind, waves, current, shallow beach, driftwood, strainers, thunderstorms, cold water, and boat traffic
- parking/fees, long portage, launch hours, private or federal shoreline, day-use/camping permits, and hard named take-outs
- Mattlingy ramp fee/parking, Naval Surface Warfare Center shoreline, Smallwood marina traffic, tidal current, and hard park take-out

NotesWhat to know before you go
These notes cover the access details, route quirks, and source caveats most likely to matter once you get there.
- Named moving-water corridorCharles County/DNR Mattawoman Creek Water Trail, Approximately 4.5 miles downstream from Mattlingy Park to Smallwood State Park
The official Maryland DNR/Charles County water-trail package names the corridor, public access, route options, and relevant distance or same-launch boundary.
- Authoritative public accessMattlingy Park public boat ramp to Smallwood State Park / Sweden Point Marina
Charles County and Maryland DNR identify the endpoint facilities. Coordinates are near-water anchors and current operation/fees/permits must be confirmed.
- Proxy flow and tidal evidenceUSGS 01658000 Mattawoman Creek near Pomonkey, MD clearly labeled proxy
The station provides regional or upstream planning context, not a local safe-flow, safe-depth, or tide cutoff. Use current marine/tide conditions and observed water.
- Camping postureSmallwood State Park publishes campsites and marina facilities; reserve separately and confirm overnight vehicle/launch rules.
Camping is separately controlled by the named park, marina, permit, or day-use rules; no informal shoreline camping is claimed.
- Live gaugeUSGS 01658000, Mattawoman Creek near Pomonkey, MD
This is a clearly labeled proxy or route-context station; local water, tributaries, releases, and weather can differ materially.
- Approved route imageryRights-cleared public-agency or public-domain corridor image
Rights-cleared Maryland public-river image used as regional context; it does not certify Charles County tide, wind, access, or route hazards.
