Dickinson Bayou is a small coastal prairie tidal stream that is tidal at its mouth with freshwater inputs from the upper watershed. The lower portion of the water body is frequently used for commercial shrimping, recreational boating, fishing, canoeing and water skiing. The upper portion of the bayou is shallower and much narrower, and is heavily forested along the banks. Dickinson Bayou watershed currently has a large amount of undeveloped land; however, it is undergoing rapid development like many coastal areas. These developed land uses are increasing as the watershed undergoes transition from agricultural and rural to suburban and urban land uses. This paper will present a review of historical data collected in the bayou and an analysis of the potential relationships between bacteria and other water quality parameters. Additionally, preliminary model results from HSPF and tidal prism modeling will be briefly discussed.
