Geography

Wellers Bay is located in Prince Edward County, Ontario, on the north shore of Lake Ontario. The bay stretches approximately 8 kilometres from north to south and varies in width from 1 to 5 kilometres.

Total surface area: approximately 18+ square kilometres

Perimeter: varies, but substantial given the bay's complex shoreline

Coordinates: approximately 43.9°N, 77.7°W

Average depth: 2.8 metres (9.1 feet)

Deepest areas: up to 8+ metres in the main channels

Shallowest areas: less than 1 metre near shores and marshes

The bay's bottom topography is complex, with distinct channels, deeper basins, and shallow areas. This variation creates diverse microhabitats supporting different fish and aquatic plant communities.

Water movement in Wellers Bay is influenced by wind, seasonal temperature changes, and exchange with Lake Ontario through the channels and over the sand spit. The hourglass shape of the bay creates distinct zones with different water characteristics, temperature regimes, and ecological communities.

The surrounding landscape is characteristic of the Prince Edward County drumlin field. The region's geology, shaped by glaciation, influences soil types, groundwater, and the streams and wetlands that feed into Wellers Bay. The interplay between upland geology and coastal geography creates the diverse habitats surrounding the bay.
