beyond the tips of the breakwaters, after which it begins to be
buoyed up by the colder denser lake water. We believe that the..effluent's river-like tendency to reach to bottom at the mouth of
the outflow channel will result in some erosion of the inner sand
bar in front of the outflow channel. We believe that the whole
of the area between the outflow channel mouth and the second
(outer) sand bar will be filled with effluent water before buoyingup by lake water begins. We believe that from this effluent-filled
area in front of the plant the plume of effluent will depart in the
downwind direction. In the cases of winds producing alongshore
currents, we believe the effluent plume will depart laterally from
this filled area, guided by the sand bars.
When there is no wind the effluent should pond in front of
its outflow channel and drift slowly away with what residual
current remains from the last wind. Under this condition the
dispersion of the effluent should be expected to be minimal.
Because of this, the percentage of calms becomes an operationallyimportant meteorological parameter.
Strong winds from directions from south through west to north
should greatly aid the dispersal of the effluent plume and the
removal of its thermal load. The frequency of strong winds from
these directions becomes also an important meteorological parameter.
During calms and light winds the convection of sensible heat
to the atmosphere will probably be the most important mechanism
for disposing of the thermal load carried by the plant effluent.
An annual curve of air temperature (for comparison against the
curves of water temperatures shown in Fig. 8) becomes an important
