Abstract : The report contains a study made for the Corps of Engineers, U. S. Army, on the periodic outflow from Lake Okeechobee through the St. Lucie Canal and its effects upon the marine life of the estuary. Stations are listed and observations presented. Evidence is presented that severe and rapid changes in salinity occurred as a result of the release of water from the lake and that damage is also being done by the sediments deposited. Other small chemical and physical changes occur as a result of the fresh water outflow, but the salinity changes and the sediment deposition are the ones sufficient to cause substantial damage to the ecology and fisheries of the area. Changes in salinity are of a transient nature only while the effects of sediment deposits are more permanent. Both game and commercial fisheries are principally affected by the salinity drop which temporarily drives the fishes to the outside of the estuary where only a restricted amount of fishing continues.
