Natural Resources Conservation Service
The first agency you'll want to check with is the Pennsylvania Natural Resources Conservation Service. Upon request, they will give you a free guide to pond building to get you started. The agency is also a valuable resource for determining if and where a pond can be constructed on your property.

County Conservation District
You must also contact your local county conservation distrist, which specializes in permitting for the meat and potatoes of building a pond--the excavation.
U.S. Army Corps of Engineers
If your property includes or is near any kind of stream, creek or wetlands, you'll have to get in touch with the U.S. Army Corps of Engineers. Should your pond be connected to one of these bodies of water or potentially overflow to them, you must acquire a 404 permit in accordance with the Clean Water Act.

Pennsylvania Department of Environmental Protection
If you plan on damming a stream to fill your pond or building an especially large pond, the Pennsylvania Department of Environmental Protection handles the regulations associated with this type of construction and special permits must be sought.

Pennsylvania Fish and Boat Commission
Contacting the Pennsylvania Fish and Boat Commission will usually only be necessary after the pond is constructed and filled and you need permitting to apply aquatic herbicides, algaecides, rotenone or stock triploid grass carp for submersed weed control. For larger ponds that require draw down to repair a structure or dredge, this commission is the agency to contact in these cases, as well.
Pennsylvania Natural Heritage Program
Though it's not a regulation per se, as a steward of the environment you afford the responsibility to be cognitive of threatened and endangered species that may be affected by your new pond. The Pennsylvania Natural Heritage Program can provide you with educational materials as well as advice on the topic.
