The levee lines feature class is an inventory of levee lines representing the centerline of levee-like features that appear to protect against flooding in the state of Oregon. It is a compilation of levee datasets from the following sources: The Oregon Department of Geology and Mineral Industries (2017), The U.S. Army Corps of Engineers (2015), The Lower Columbia River Partnership (2012) and The Oregon Coastal Monitoring Program (2011). A geospatial inventory of levees and levee-like features is an important resource for assessing flood risk, flood mitigation planning and for emergency response during flood events. It also benefits ecological restoration efforts by helping locate levees to remove or breach in order to expand habitat for aquatic species. Until now, the state of Oregon did not have a single comprehensive inventory that maps levees with the high spatial accuracy needed to support these activities. To meet this need, the Oregon Department of Geology and Mineral Industries (DOGAMI) created new levee data and compiled pre-existing levee data into a single geospatial inventory.

Mineral Information Layer for Oregon-Release 3 (MILO-Release 3) is a geospatial database that stores and manages information regarding Oregons mineral occurrences, prospects, and mines. Understand that recreation in or around inactive mine sites is extremely dangerous, and can result in serious injury or death. Stay out and stay alive!
