up to the sides of the outfall plume or channel. Some limited melt to shore in
the recent past which has refrozen could be observed at the Bailey Power Plant
on March 5th. Only at the Campbell plant site was there an exposure of bare
beach that could be attributed to its outflow.
Except for Campbell there was no evidence that discharged waters were melting
shore ice and exposing the beach to erosion. Even at Campbell there was no visible
evidence of erosion even though the beach was bare.
A brief summary description and discussion of each slide is presented in
Table 1.
