3. COMPILATION OF INFORMATION 
Most of the information relating to sources of data is of such na- 
ture that it can be readily tabulated. In Table 1 are listed sources of 
hydrographic and/or meteorological data that are located on the peri- 
phery of the Lakes. All meteorological stations located no farther than 
two miles from the lake shore are included in this table. Entries have 
been listed geographically, proceeding counterclockwise around each Lake, 
as noted in the table. 
In Table 2 are listed all those sources of meteorological data oc- 
curring within the Great Lakes drainage basin but located more than two 
miles from the nearest Great Lake. Geographical listing by state or 
province is shown. It is not feasible in Table 2 to list each station 
geographically, hence items have been entered alphabetically by state or 
province. Individual stations may be located by use of the included 
coordinates. 
To facilitate geographical orientation, a series of six orientation 
plates have been included, five within Table 1 and one preceding Table 2. 
Figures 2 through 6 depict the five Lakes: Superior, Michigan, Huron, 
Erie, and Ontario. The St. Marys River appears in Figure 2, and the St. 
Clair River, Lake St. Clair, Detroit River, and Niagara River in Figure 
6. Figure 7 shows the entire area of the Great Lakes drainage basin. 
All meteorological sources within this basin that have been ascertained 
by the present research are listed, partly in Table 1 and in all of 
Table 2; all hydrographic data sources on the periphery of the Lakes are 
listed as part of Table 1. In addition, station circles are shown in 
Figure 7 outside the drainage basin periphery. These are meteorological 
stations that are in close proximity to the basin periphery. They are 
listed as part of the present research since there are frequent occur- 
rences where suitable data sources close to the periphery, but within the 
basin, are not available. 
Table 3 contains all those sources which, for specified reasons, had 
no usable data, or so few that they were considered unsuited to the pur- 
poses of this study.
