Delta College is a two-year community college located southwest of Bay City, Michigan. Delta College's district had its beginning in 1955 with Saginaw, Midland, and Bay counties making up the district. In 1957, the voters of the tri-counties approved the construction of the college, and it opened for classes in 1961. Delta College replaced Bay City Junior College, established in 1922, because the junior college could no longer support the growing enrollment. With Saginaw Valley College established in 1964, later renamed Saginaw Valley State College in 1975, and finally named Saginaw Valley State University in 1987, both Delta College and Saginaw Valley State University form University Center, Michigan. Delta College has off campus centers in each of its three neighboring counties: Delta College Planetarium and Learning Center in Bay City; Delta College Midland Center in Midland; and the Ricker Center in Saginaw.
