This feature class resides within the SOCECON Feature Data Set of the Great Lakes St. Marys River 2021 ESI Geodatabase. It contains vector points representing Navigational/marine human-use resource data for the Great Lakes St. Marys River System and adjacent lands and waters. The study area includes the St. Marys River at the southern portion of Lake Superior beginning just east of Monocle Lake and south of Iroquois Island ending to the headwaters of Lake Huron. This data set contains information about the following resources: anchorages, boat ramps, ferry terminals, lock and dam systems, and marinas in the St. Marys River. Object specific Type and Source information are stored in the related data tables, SOC_DAT and SOURCES (described below). These are stand-alone tables within the Geodatabase, designed to be used in conjunction with these spatial data layers. This data set is a portion of the ESI data for Great Lakes St. Marys River System. As a whole, the ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil, and include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.
