The depth of each of these zones will vary from reservoir
to reservoir according to seasonal temperature changes. In the

summer months, the Active Zone may reach a depth of 10 meters;

J

while in the winter months the zone may only reach a depth of i

or 2 meters . Accordingly, the depth and size of the 7 Transitional
Zone will be reduced in the winter montas and ‘tha at of the ‘Static

Zone will be increased.

In reservoirs where annual fluctua

occur, zone leveis willimove-wp’ and. down:
a result, many archaeological si ites wil be sub je cted to the ale

ternating processes of the various zones depending « on the season.

Conversely, some sites will, not be subjected to ‘the “destructive
processes of 7 the various zon ynes depending on s: site location and ~
elevation within the reservoir.

The preservation and administration of archaeological re-
sources is contingent on understanding wnat will happen to archaeo-
logical sites once inundation occurs. Thus, understanding the
dynamic processes of the various zones and monitering their effects
on selected ar rchasological sites during the inundation phase of
future water resource development projects would be of considerable
value in archaeological resource studies. On the Arrow Lakes,

these types of studies were not conducted as most inundated sites

had been destroyed before the 1977 inventory pro oject commenced.
