Mean High Water is the average of the annual high water levels over many years.
Appendix Q-2 of the Adirondack Park Agency Rules and Regulations, promulgated in 1982, established Mean High Water Mark elevations for eight bodies of water as follows:
Great Sacandaga Lake
Lake Pleasant (Hamilton County)
Sacandaga Lake (Hamilton County)
Since 1982, Agency staff have determined mean high water elevations for five additional water bodies. The elevation determinations for the bodies of water listed below were based on either analysis of staff guage readings over a several-year period, or conclusive field evidence.
Upper Chateaugay Lake
These most recent elevation determinations have not been codified but are used in the review of permit applications to the Agency, as well as enforcement and/or jurisdictional determinations.
