Estimating Streamflow for Base Flow Conditions at Partial-Record Streamgaging Stations at Acadia National Park, Maine

Lombard, Pamela

The Otter Creek near Bar Harbor, Maine (01022849) streamgage was established as a continuous-record streamgage on Mount Desert Island (fig. 2), in part because of its potential to function as an index station for the partial-record stations in the NETN water quality and water quantity station network at Acadia National Park. Although 15 years of data had been collected at Otter Creek and at the partial-record stations, the study in this report is the first comprehensive analysis to determine which of the 14 partial-record stations could use Otter Creek as an index station for record extension. One goal of this work was to determine if streamflow at the Otter Creek station correlates with enough partial-record stations to justify its continuation as an index station. Another goal was to analyze data at the partial-record stations to ensure that the data were of sufficient quality and quantity to support NETN stream monitoring protocol objectives (Gawley and others, 2016) and determine if other potential index streamgages could be used to extend the records of partial-record streamgages that did not correlate well with the Otter Creek station.
