A. Public Health Service 
The 1961 Appropriations Act included $500 thousand for the Public 
Health Service to commence development of a comprehensive water pollution 
control program for the Great Lakes. During the first three years particular 
effort was devoted to the Illinois Waterway at the Southern end of Lake 
Michigan. The most important project within the overall program concerns a 
series of 11 current measuring stations forming the first part of a 52 station 
network, These form a preat pattern covering the entire area of Lake Michigan. 
Sensitive automatic recording devices measure winds, currents, tomperatuz'e, 
and related environmental conditions; the information is stored for several 
months on photographic film. The Public Health Service has opened a ‘field 
basin. According to the plan, investigations are to proceed to Lake Huron, 
Lake Ontario, and Lake Superior in that order. They are scheduled over a 
seven year period and are considered to be approximately 40% complete to S533 
The pot ovane projects are contractually supported by the Public 
Health Service.
