The Area's Water Resources

THE St. Louis Metropolitan Area is regarded as including St. Louis, the three adjoining counties in Missouri, and three counties on the opposite side of the Mississippi River in Illinois {see Fig. 1). This comprises a total population of nearly 2,000,000. St. Louis and St. Louis County are separate political entities. This metropolitan area is that in which the BiState Development Agency, by special acts of the Missouri and Illinois legislatures and by Congress, has been authorized to function. The organization of this agency was patterned after that of the Port Authority of New York.
