#PointTypeLat, LonNotes
1Moraine State Park Dam
West end of the lake		Dam / hazard40.96301, -80.12304The dam that impounds Lake Arthur and the head of Muddy Creek below it. An unnamed OSM weir 100 m west is the same structure and is not shipped twice.
2Butterfly Trail launch
North shore by the dam - unnamed in OSM		Access / boat ramp40.96747, -80.12389The northernmost ramp at the dam end of the lake. OSM carries the slipway with no name and a zoom-17 reverse geocode returns only the Butterfly Trail beside it, so the trail is used rather than a name no source carries.
3Five Points Organized Group Tenting Area
Moraine State Park - DCNR, reservation only		Campsite40.97042, -80.11241One of the park's two rustic group tenting areas. DCNR lists restrooms, picnic tables, cooking grills and water, and no showers. Ordinary camping is prohibited in the park.
4Lakeview Beach
North Shore - Moraine State Park		Park / conservation area40.96150, -80.11156DCNR's 656-foot sand beach on the north shore, about five miles in from PA 422, with a concession, showers and changing rooms. Open Memorial Day weekend to Labor Day; pets are not permitted.
5Watts Bay Marina
North Shore - dry mooring for sailboats		Access / boat ramp40.96186, -80.09890DCNR's dry-mooring marina for sailboats and catamarans, and the home of the Moraine Sailing Club. Two unnamed OSM slipways within 150 m are its ramps and are folded in rather than shipped as separate dots.
6Davis Hollow Marina
North Shore - DCNR marina, fuel and mooring		Access / boat ramp40.95999, -80.06928Motorboat fuel, a boat sanitary dump station and seasonal mooring. The marina office issues launch permits and park information April 15 to October 30. An unnamed slipway 220 m west on North Shore Drive is its own ramp.
7PA 528 bridge launch
North side of the PA 528 crossing		Access / boat ramp40.95199, -80.04056DCNR names a 528 Bridge Boat Launch and this is the ramp on the north side of that crossing, 200 m north-east of the mapped PA 528 bridge. OSM carries three unnamed slipway nodes within 20 m here; they are one launch.
8Mt Zion Baptist Church Road launch
Unnamed in OSM - named from its road		Access / boat ramp40.94722, -80.04010The ramp on the south side of the PA 528 arm, about 500 m below the bridge. No agency page read this run names a launch here, so the road a reverse geocode returned is used instead.
9Barkley Road launch
Head of the lake - named from its road		Access / boat ramp40.96916, -80.02279The easternmost ramp on the sheet, at the shallow upper end of the lake in Brady Township. OSM carries the slipway unnamed.
10Duck Pond Dam
Above the head of the lake		Dam / hazard40.97277, -80.00969A small dam at the extreme east end, above the open water. A structure with moving water rather than a place to put a boat in.
11Park Road Boat Launch
South Shore - Moraine State Park		Access / boat ramp40.92367, -80.06910DCNR names a Park Road Boat Launch on its accessible-facilities list and a zoom-17 reverse geocode here returns Park Road, so the agency name is used. The OSM slipway itself is unnamed.
12Muskrat Cove Organized Group Tenting Area
Moraine State Park - DCNR, reservation only		Campsite40.92866, -80.07088The south-shore rustic group tenting area, on the cove OSM names Muskrat Cove 190 m north. Restrooms, picnic tables, grills and water, no showers. Ordinary camping is prohibited in the park.
13Crescent Bay Boat Rental
Appalachian Outdoor School concession		Outfitter / canoe rental40.94658, -80.09134Pontoon boats, motorboats, kayaks and canoes, plus motorboat fuel and fishing bait. DCNR's boating page names the concessionaire Appalachian Outdoor School; its accessibility page calls the facility here Crescent Bay Boat Rental.
14Sunken Garden Trail launch
South shore - unnamed in OSM		Access / boat ramp40.94059, -80.09115A ramp on the south shore below Crescent Bay. OSM carries no name and a zoom-17 reverse geocode returns only the Sunken Garden Trail beside it, so the trail is used rather than an invented name.
15Bear Run Boat Launch
South Shore - Moraine State Park		Access / boat ramp40.94880, -80.10778DCNR names a Bear Run Boat Launch with a stabilized shoreline, and a zoom-17 reverse geocode here returns Bear Run Drive, so the agency name is used. Two unnamed OSM slipway nodes 10 m apart are shipped as one.
16Bear Run Campground
Private campground, 0.6 km off the south-west shore		Campsite40.92804, -80.12326Camping is prohibited inside Moraine State Park, so the nearest camping is private. This is the closest to the water of several private campgrounds around the lake.
17Porters Cove launch
South-west corner - unnamed in OSM		Access / boat ramp40.93928, -80.12659The ramp at the south-west corner of the lake, reached from the Porters Cove equestrian trail road. OSM carries the slipway with no name.
18USGS 03106280 - Lake Arthur at Moraine State Park
United States Geological Survey		USGS gauge40.96256, -80.12117The gauge on the roster for this water. USGS files it as a lake site rather than a stream site, so it reports lake level at the dam end rather than a discharge.

About the Lake Arthur

Lake Arthur is the centrepiece of Moraine State Park, an hour north of Pittsburgh, and it is one of the best examples anywhere of a lake built deliberately for recreation and managed accordingly. It is shallow, weedy and fertile, with long shallow arms, extensive vegetation and a slow-speed rule over nearly all of it.

Muskellunge are the signature fish. The state stocks them, the weedy shallow habitat suits them, and Lake Arthur has a long-standing reputation among Pennsylvania muskie anglers as a place where a serious fish is a realistic outcome of a season rather than a lifetime. Largemouth bass fishing in the vegetation is very good, walleye are present and stocked, and northern pike add another predator to the mix.

The panfishing is excellent and much of it is reachable from the bank, which makes Arthur a genuinely good family lake as well as a specialist one. Crappie around the wood and bluegill on the beds in early summer are both dependable.

Moraine is also one of the best-organised fishing parks in the state. There are launches on both shores, marked shoreline access, and enough parking that a busy Saturday does not turn into a queue. For an angler new to muskie fishing, the combination of stocked fish, forgiving water and easy logistics is about as gentle an introduction as the species allows.

The horsepower and speed rules keep the lake calm and slow, and they are the reason it fishes as well as it does on a summer Saturday. Kayaks, canoes and small electric-powered boats are entirely at home here.

The gauge below reports pool elevation. Arthur is shallow enough that a modest level change moves the weed edge substantially, and the weed edge is where the muskie, the pike and most of the bass are.
