Presque Isle Peninsula, a sandy spit on the south shore of Lake Erie, has experienced continued erosion of its lakeside shoreline ever since first attempts to stabilize and halt its natural eastward migration. For nearly 150 years numerous structures have been built on the shoreline in attempts to slow down or halt the deterioration and migration of the Peninsula and consequent loss of valuable land. In 1965, approximately 1.27 x 104 m3 of sand fill, coarser than fill previously used as well as coarser than that which naturally existed on the Peninsula, was placed on a section of the beach; subsequently annual data collection surveys were made in the fill area and in or adjacent parts of the Peninsula. Analysis of the data indicate the test area involving coarse sand fill has undergone minimal material loss and maintained a relatively stable profile. On the basis of this experiment it is judged that definite shore stabilization occurs, with attendant benefits such as substantially reduced nourishment requirements, from the utilization of sand fill that has size characteristics superior to that originally found on an eroding beach.
