Head of Tide data has been screen digitized with reference to Bill Hinkley's 1974 River Sampling Station description guide, USGS zero contour data, as well as salinity sampling results from the Maine Department of Environmental Protection and the Maine Department of Marine Resources. Data points may represent known or approximate Head of Tide location based on hydraulic activity, environmental sampling data, and/or zero contour data. Data is considered to be dynamic in a small degree due to land use, natural evolution, and human activities. Data is also subject to changes, updates, and revisions. Field Data Attribute info: HTtypeHS = based on salinity and hydrological data. SAL = based on salinity sampling. HYD = based on hydraulic information or data. HTnotesSWQ = Statute Water Quality (can be arbitrary). RSS Hinckley 1974 = excerpt from Hinckley's 1974 River Sampling Station descriptions. ZC = based on USGS zero contour data* note that an individual point may have one or more notes associated with it. HTLocation: Completed where there is a notable physical attribute associated with the point location. |
