Is Lake Hopatcong rising or falling?
Across the readings available for the last seven days, Lake Hopatcong is falling. The measured change over that window is -0.08 ft. Short-term changes can reflect rainfall, inflow, dam operations, evaporation and downstream releases.
This reading should not be confused with a reservoir's published “full pool” unless the operating agency uses the same datum and reference elevation. Lake Conditions Lab does not guess at full-pool comparisons.
