should be desired.
The indicated currents varied from zero to tens of centimeters per second. In general the greatest indicated currents
occurred in the surface layer and along either the east or west
shore of the lake.
In general, the velocities of the indicated currents decreased toward the bottom and in the central portion of the lake.
Streaked Nature of the Indicated Currents
Quite unexpected was the fact that the indicated currents
were arranged in alternate streaks of northward and southward
current.,
0
The widths of the alternating current streaks varied,
apparently in response to the wind regimen. The locations of
the streaks also appeared to vary under different winds.
The streaks of current in most cases reached to the 60 -ri
meter level, although there were some instances owhere they did
not.

The indicated structure of the currents is similar to the
horizontal current-countercurrent arrangement suggested by
Fuglister (1951, 1955) for the Gulf Stream, and confirmed by
von Arx, Bumpus, and Richardson (1955). Fuglister's initial
presentation of this current arrangement is shown in Figure 1.
The alternation of northward and southward current bands
shows clearly in the underlined (north) and not underlined
(south) indicated currents of Tables 3, 6, 9, 12, 15, 18, 21,
and 24. 0
