In the consideration of problems of coastal engineering in general, and of shore and beach erosion in particular, one is quite naturally apt to immediately focus attention upon our ocean shores to the exclusion of inland areas. Many are perhaps not appreciative of the fact that the five inland fresh-water lakes comprising the Great Lakes system are bordered by eight states having a combined length of shore line of approximately 3,000 miles. (See Fig. 1) Only in recent years has there been a general awakening of interest in the many and varied problems of erosion which occur along these inland coasts. The purpose of this paper is to summarize the problems existing on the Illinois shore and to outline the steps which have been taken at the State level in seeking a solution to those problems.

The cod family is represented in Illinois by only a single species, the burbot (Lota maculosa), occurring in the interior of Lake Michigan, and making its way at irregular intervals to the shallow waters within the reach of ordinary fishing operations. Since the opening of canals between the Great Lakes and the river systems of the State, occasional specimens have been taken in the Illinois and Mississippi. Its predaceous character is too well known to make special description of its alimentary structures necessary. It is reported by Mr. G. Brown Goode to feed upon various small fishes and Crustacea which frequent the bottom, devouring more particularly fishes with habits like its own. It is extremely voracious, with a wonderfully distensible stomach; and not only captures the most active fishes, such as the pike, but will eat carrion, and may even swallow stones. It is reported to be nocturnal in habit, and often to secure its prey by stealth.

Sand Supply

A natural beach system is in equilibrium when there is a balance between sand supply and erosion such that the volumes of material entering and leaving the system are just equal. If the erosion rate exceeds the supply rate, a beach retrogrades; if the erosion rate is less than the supply rate, a beach progrades. Unfortunately, coastal engineering works, which are meant to improve the shore for commerce or recreation, often upset this delicate balance with very deleterious results: great accretions of sand and high dredging costs, accelerated beach erosion and much property damage. It is the task of the geologist to determine the secular equilibrium conditions of a beach system and to supply the coastal engineer with the information he needs to control the natural forces acting on the shore in such a way that this equilibrium is maintained. In order to accomplish this task, the geologist needs to make a thorough study of the source, transportation, and deposition of beach sediment. He must determine the stable position of the shore line and the profile of equilibrium of the beaches through detailed physiographic investigations. The geological report can and should close with the prediction of just what will happen to a natural beach system if man introduces a disturbing element.

Existing Data

The General Investigations program of the Beach Erosion Board comprises investigations, regional rather than local in scope, designed to improve, simplify, and expedite the solution of local problems, by giving a compilation of all existing data pertinent to shore processes in the particular region. As a first step in the compilation of these data, a study of wave and lake level conditions on the Great Lakes is being made. The results of such studies for Lake Michigan, Lake Erie, and Lake Ontario have recently been completed and published as Technical Memorandums of the Beach Erosion Board (Saville, 1953).

Local Agencies

The purpose of this paper is to describe the methods by which, and the extent to which the Federal Government participates with local agencies in the control of beach erosion. The Beach Erosion Board of the Corps of Engineers is the instrumentality through which this participation is affected. However, before describing this Board, it is necessary to sketch very briefly the background of the beach erosion problem as viewed from the national standpoint. The necessity for the control of beach erosion by one means or another has no doubt been recognized from the beginning of the practice of coastal engineering in the United States. The early technical records of the Corps of Engineers contain numerous references to the mutual effects which navigation structures and the adjacent shorelines exert upon each other. As an example, chosen at random, I may mention the construction in 1874 of twelve stone groins along the shore of the State of Connecticut between Welshs Point and Indian River, and of a stone jetty at the mouth of that river in the following year, to stabilize the shoreline and to prevent the movement of sand into the navigation channel of that river.

Near the southern tip of the Indian peninsula, the State of Kerala has a 400 miles long shore line running north from the Cape Camorin. Almost all along its length is one reach or the other, the coast has fine beaches which are continually subjected to erosion due to wave action. This process has been going on, no doubt, since the existence of the sub-continent, but it is only in recent years has there been an awakening of interest when property and plantation are being threatened, as the man-land ratio is getting dangerously high.

This handbook is designed to provide an accurate, current, and authoritative summary of the principle Federal and Florida laws that directly or indirectly relate to agriculture. This handbook should provide a basic overview of the many rights and responsibilities that farmers and farmland owners have under both Federal and Florida laws as well as the appropriate contact information to obtain more detailed information. However, the reader should be aware that because the laws, administrative rulings, and court decisions on which this handbook is based are subject to constant revision, portions of this publication could become outdated at anytime. Several details of cited laws are also left out due to space limitations. This document is FE601, one of a series of the Food and Resource Economics Department, UF/IFAS Extension. Published December 2005.

Specimens of Coregonus clupeaformis, Prosopium quadrilaterale and Leucichthys artedi from Hudson and James bays are quite similar to specimens of the same species from the Great Lakes; Prosopium shows the most divergence.Coregonus does not grow as large in salt water as in fresh water lakes of the same latitude; its rate of growth is more rapid than that of whitefish in lake Nipigon, but slower than in lake Ontario; spawning fish are usually at least seven years old.For the first two or three years Leucichthys grows more slowly, but later more rapidly than in lake Ontario or Saginaw bay, lake Michigan; it also reaches a larger size than is usual in the Great Lakes; sexual maturity is probably not attained until at least the fourth year.

During the course of investigations of ice forms on the Great Lakes bordering the state of Michigan, the writers had occasion to observe several shore areas under winter conditions. The following paper is a general consideration of these casual observations and includes suggestions of the probable relationship between ice conditions at the shore line and in the surf zone to the normal shore processes effective during the ice-free year.
