Extensive improvements for navigation have been made in the St. Clair‐Detroit River (hereafter referred to as SCDR). It is shown that channel changes have lowered the level of Lake Michigan‐Huron by about 2 feet, bringing about the lowest levels of record in 1964 and 1965. The unrecognized changes in the regimen of the SCDR before 1900 have also resulted in the determination of flows that are much too large. The discharge of Lake Erie and the precipitation in the Erie basin are used to derive more reasonable estimates of the flow of the SCDR before 1900.
