Gene W. Parker 1981 <p>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.</p><p>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.</p> application/pdf 10.3133/ofr81545 en U.S. Geological Survey Time-of-travel study in the Sebasticook River basin, Maine reports
