As the
land was cleared and agricultural and urban
development took place, natural drainage and
runoff patterns changed. Water levels and flows
varied and floods became more frequent. The flood
of 1937 caused extensive damage despite the
presence of dikes in many communities.
The
Upper Thames River Conservation Authority was
created in 1947 and built dams at Fanshawe (1950-52), Pittock (1964-67) and Wildwood (1965).
Throughout the watershed flooding is now reduced
through flood control structures. An extensive
system of dikes along the lower Thames between Thamesville and the river's mouth minimize
flood damage in low-lying areas.
