• Abstract:
  This report summarizes the results of a two-year water quality monitoring project to document the effects of ; the construction of the Highway 1 bypass on the water quality of Crane (Crains) Creek and the Little River. ; Automated monitoring equipment were installed upstream and downstream of the highway corridor on both Crane ; Creek and the Little River. For Crane Creek, discharge was monitored and samples of creek water were collected on ; a flow-proportional basis throughout the project, while for the Little River samples were collected every 6-8 hours ; during the project. A recording raingage was also maintained for most of the study at Crane Creek and in-situ ; measurements of temperature, dissolved oxygen, conductivity, and pH were made at least monthly. ; The mean suspended sediment concentration and turbidity for Crane Creek was 48 mg/L and 40 ntu upstream ; and 38 mg/L and 26 ntu downstream of the highway corridor. Statistical analysis of the bi-weekly sediment load ; data from both sites showed that the loads at the upstream site were not significantly different than the downstream ; site indicating that the construction had no effect on sediment loads of Crane Creek. The mean turbidity of samples ; was greater upstream compared to downstream, which also indicates no negative effect of highway construction. ; Means of temperature, dissolved oxygen, conductivity, and pH were nearly the same upstream and downstream ; indicating no effect on these water quality parameters. ; Monitoring results for the Little River were similar to Crane Creek in that there were no significant ; differences between upstream and downstream sites according to paired t-tests conducted on the bi-weekly data. The ; mean suspended sediment
