Three summer field seasons have been used to study methods for assessing impact of construction activity on arctic tundra lakes in terms of change in suspended sediment load regime. An aerial photographic method for evaluating and monitoring distribution of suspended sediment loads was investigated in addition to studying suspended sediment impact on primary productivity. Films and cameras were compared during the first season. During the second season, good quality aerial photographs were taken of lakes with large gradients in suspended sediment load. Two field efforts were conducted in the third field season. Total primary production (benthic and pelagic) was found to be approximately 5 times greater with about one order of magnitude less suspended sediment load (1.46 mg/l vs. 10.22 mg/l). On 21 August 1977 an aerial reconnaissance of the pipeline and haul road was accomplished from Galbraith Lake north to Coleen Lake. The only lakes with observable suspended sediment load from 5,000 feet altitude were lakes with resuspended sediment from wind generated wave activity.
