Penobscot River Cross Section Data pre- and post-Dam Removal

The Great Work and Veazie dams on the lower section of the Penobscot River were removed during 2012 to 2013. Channel cross sections adjacent to the dams were surveyed before and after the dams were removed. Data for each cross section include total station theodolite survey data integrated with Acoustic Doppler Current Profiler (ADCP) data referenced from the water surface at the time of the survey to make up integrated cross sections. At the higher flows more data were collected by the ADCP at the edges of the cross sections. There are some gaps in 2009 from where the ADCP data ended and the total station data began. At the lower flow (2010) these edge data were collected wading with the total station, and the gaps were filled in.
