The Long Point Region watershed takes in an area drained by more than 30 creeks and tributaries. These creeks drain an area of 2,782 sq. km (1,080 sq miles) in portions of Brant, Elgin, Haldimand, Norfolk and Oxford counties.
Major communities include Port Burwell and Straffordville in Elgin County; Norwich and Tillsonburg in Oxford County; Delhi, Waterford, Simcoe and Port Dover in Norfolk County; and Jarvis and Hagersville in Haldimand County.
The watershed has been divided into six main subwatershed areas: Big Otter Creek, South Otter/Clear Creek, Big Creek, Dedrick/Young/Hay Creek, Lynn River/Black Creek and Nanticoke/Sandusk/Stoney Creek. All of the subwatersheds drain directly into Lake Erie. Each subwatershed has unique features relative to their land base and land use that affect the health of the overall Long Point Region watershed.
