Description:
Marquette Lake is a body of water that is maintained by Fort Indiantown Gap. It was used during WWII to train troops to load and unload watercraft. This lake is a triangular shaped body of water and is about 360 yards wide across the dam breast and 350 yards from the dam breast to Indiantown Run stream entrance. This lake is well stocked and a favorite of locals, and gets a lot of pressure. The local rod and gun club have john boats that can be reserved if you are a member. The intersection of Marquette Lake and Indiantown Run has been a favorite of fly fishermen and you can watch multiple fly fishermen work the water on any spring morning. I caught my first trout at Marquette Lake with my father. It’s the last place we went fishing together in the spring of 2011. Of course he caught more that day than I did that day. Marquette Lake is a favorite spot just for the nostalgia from my perspective.

Editor’s Observation:
Marquette Lake is a great place to expose kids to fishing. Freshly stocked trout take just about anything to include yellow rubber worms. Indiantown Run is always fun to fish and is a great plan B if the trout are not hitting in the lake. The spill way has a large pool that has panfish and trout that made it over the spillway. Early spring can include watching the suckers spawn as they make the run up the small stream that empties out of the spill way. Check regulations on bait restrictions. Marquette Lake was artificial lures only for decades.
Access:
Fort Indiantown Gap is a totally open to the public. There are no gates or traffic control points to manage who is permitted on base. PA Highway 934 runs through main post from Annville to Jonestown. PA 443 comes in from Pine Grove past Moon Shine Church http://www.weirdus.com/states/pennsylvania/local_legends/moonshine_church/index.php
The open access allows for the heavy pressure on the fishing in the bodies of water found on the post. PA Fishing licenses are required. Do not attempt to fish without a license. More game wardens in Pennsylvania checked up on me than all the other states combined. (Not for violations but for friendly talking about the conditions that day). Poaching is a serious incident in PA.
From PA 934: At Funcks Restaurant, take Asher Mine road (Indiantown Road) north toward the mountains. At Point #1, Cross Clement and take Lake road to Marquette Lake. You may decide to take a left (west) on Clement to 17th Street and park below the dam breast (Point #3)
From PA 443: At Point #2, intersection of 443 and Happy Street, head west towards the lake. Parking along the lake is limited near the boat ramp (Point #4)
Point #1 (Lat/Long 40.431503 -76.594172) Is the intersection of Clement Road and Lake Road. Parking is available along the road up to the dam breast with additional parking below the dam breast off 17th Street Point #3.
Point #2: (Lat/Long 40.439076 -76.598550) This is the intersection of PA 443 and Happy Street. Road is narrow and at one time was restricted to one way (away from the lake)

Point #4: Boat Ramp
Launch Site: Excellent boat ramp (Point #4) on the north side of the lake where Happy Street ends on the north bank. Parking is available.
Bank Fishing: There are some steep drops on the southern bank but pretty much the entire shore line is open for fishing. The Dam Breast is the most popular spot and the spillway gets the most attention.
Timing: Stocking dates drive this but typically mornings are best. Opening day is worth witnessing the shoulder to shoulder tradition at Marquette Lake, but you must sake out your spot before dawn. The lake can get muddy when the Armor and Infantry Brigades of the 28th Division (PANG) go to the field for maneuver training and cross the creeks with their tracked vehicles.
LOGISTICS:
Lodging: Several Hotels are nearby along I-81. Post has some rustic temporary lodging rooms.
Food: Funck’s Restaurant is the closest and opens early for breakfast. Harper’s Tavern is close by as are several establishments near Jonestown. The Lickdale Legion Post 910 near Jonestown on 934 has good food and drinks. (https://www.facebook.com/Post910/)
