Seepage beneath Hoover Dike southern shore of Lake Okeechobee, Florida
Future water needs in southern Florida call for an increase in the storagecapacity of Lake Okeechobee. Seepage from the lake is expected to increase as aresult of raising the lake level. Data concerning the occurrence and amounts ofseepage are needed for the design and operation of flood-control works whichwill remove excess water from the rich agricultural lands along the southernshore. Intensive studies at five sites along the southern shore of LakeOkeechobee between the Caloosahatchee Canal and the St. Lucie Canal indicatethat seepage occurs chiefly through beds of shell and limestone which underliethe Hoover Dike at shallow depth. Seepage rates at the five sites range fromabout 0.1 to 0.9 cfs per mile per foot of head across the dike. Seepage beneaththe 50-mile length of dike should increase from about 22 to 50 cfs if the averagestage of the lake is raised from 14 to 16.5 feet. Seepage is greatest betweenMoore Haven and Clewiston, where deep borrows have been excavated on thelandward and lakeward sides of the dike. Most of the seepage from the lake canbe controlled by properly spaced toe ditches which would intercept the seepageand return it to the lake. (PDF contains 108 pages.)
