Scope of Our Efforts: Water Level Stations Along the US Coast

An update to the NTDE means that CO-OPS will be recomputing datums from thousands of water level stations, both active and historic, in 23 coastal states and several US territories. There are currently about 250 active stations and 1,730 historic stations that will receive up-dated datums and benchmark sheets.
