Why Lake Wallenpaupack has no grade
Lake Wallenpaupack has monitoring on record from one station, but only water clarity was measured. LakeQuality’s A–F letter uses total phosphorus, total nitrogen, chlorophyll-a, and turbidity against EPA National Lakes Assessment condition classes. With none of those grading measurements on record, Lake Wallenpaupack is Not Rated — not an F. Its 5.7-foot median from 570 readings collected 2020–2024 is still shown as clarity, but clarity alone cannot earn a letter.
Not Rated is EPA Integrated Reporting Category 3 — insufficient information. Everything below that has been measured is still reported on this page.
Sampling is run by PA DEP and volunteer programs, and published through the EPA Water Quality Portal. Read the full grading methodology.
Lake Wallenpaupack is a lake in Pike County, Pennsylvania with an estimated average depth of about 77 feet. Overall water quality is improving over recent sampling years. Limited fish-species data available. Public access is available with 7 public boat landings.

Depth marked “est.” is a modeled maximum from GLOBathy (Khazaei et al. 2022, CC0), not a measured survey. Pennsylvania has not published bathymetry for Lake Wallenpaupack.
Lake Size & Watershed
Size, shoreline, and watershed area from HydroLAKES (HydroSHEDS). Mean depth here is modelled, not surveyed — HydroLAKES v1.0 estimates lake depth from surrounding terrain rather than from soundings. Treat it as an approximation, and prefer a state bathymetric survey where one exists.
