AbstractFollowing glacial meltwater diversion to the Ottawa River valley about 12,300 cal (10,400) BP, Lake Erie descended in the dry early Holocene climate to a hydrologically-closed lowstand about 3-15 m below the basin overflow outlet. The lowstand is indicated by a submerged and mud-buried beach-shoreface and a wave-cut clay terrace. Lake Erie remained in closed-basin status for >6 millennia until it began to receive increased atmospheric moisture and discharge from the upper Great Lakes about 5760 cal (5000) BP.
