Name: Maine - Head of Tide

Display Field: HTNAME

Type: Feature Layer

Geometry Type: esriGeometryPoint

Description: 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 salinty 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 revisons. Field Data Attribute info:HTtypeHS = based on sality and hydrological dataSAL = based on salinty samplingHYD = based on hydraulic information or dataEL = Enforcement Location Head of Tide for DMR & IF&WHTnotesSWQ = Staute Water Quality (can be arbritrary)RSS Hinckley 1974 = excerpt from Hinckley's 1974 River Sampling Station descriptionsZC = based on USGS zero contour data* note that an individual point may have one or more notes associated with itHTLocation:Completed where there is a noteable physical attribute associated with the point locationMisc Informaiton - Enforcement Location DescriptionsDMR and IFW are in agreement as to the location of head of tide on the Kennebec for enforcement purposes.DMR references head of tide as this:Due to the removal of Edwards dam, the “head of tide” in the Kennebec River is now at the downstream side of the power line located approximately 4,200 feet upstream of the Calumet Bridge at Old Fort Western in Augusta (formerly the Father Curran Bridge) for enforcement purposes.IFW references head of tide as this:From the downstream side of the Lockwood Dam to the downstream side of the power lines located about 4,200 feet above the Calumet Bridge in Augusta (head of tidewater):
