River Basin Surveys Papers, No. 38: Archeological Investigations in the Toronto Reservoir Area, Kansas

The Toronto Dam and Reservoir, a flood-control and conservation project of the U.S. Army, Corps of Engineers, Tulsa District, is located on the Verdigris River in Greenwood and Woodson Counties, southeastern Kansas (see fig. 59) . The dam is a rolled, earthfill structure, 4,712 feet in length and 90 feet in height, above the river channel. It is 3% miles south of the town of Toronto in Woodson County, Kans., 55 miles north of the Oklahoma border, and 75 miles west of the Missouri border. It forms a reservoir some 11% miles long, with a maximum width of approximately 1% miles at full-pool level of 931 feet ( m.s.l.). This reservoir extends up the Verdigris River and its tributaries in the eastern portion of Woodson County and the western
portion of Greenwood County to cover a total area of approximately 10,000 acres. Dam construction was begun in November 1954 and was essentially completed in December 1959. Flooding of the reservoir began in the spring of 1959 with maximum pool level to be reached
intermittently after completion.
