Time-of-travel study in the Sebasticook River basin, Maine

Time of travel was determined for four reaches of the Sebasticook River, two on the East Branch Sebasticook River, and two on the main stem of the Sebasticook River. Reach A included 7.8 miles of the East Branch Sebasticook River from Dexter to Corinna, Maine. Reach B included 8 miles of the East Branch Sebasticook River from Newport to its mouth, and 1 mile of the Sebasticook River to Peltoma bridge near Pittsfield, Maine. Reach C included 3.5 miles of the Sebasticook River from Hartland to West Palmyra, Maine. Reach D included 31.4 miles of the Sebasticook River from Pittsfield to Winslow, Maine. Using a 20-percent solution of rhodamine WT fluorescent dye, three dye-tracer type time-of-travel study runs were made in each reach. Water samples were collected at 10 sites in the study area. The samples were then analyzed for dye concentrations.

Time-of-travel data for each subreach are depicted in a series of illustrations and summarized in tabular form. Examples are given to illustrate use of the data presented.
