High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management. The U.S. Geological Survey has recently published a guidance document for "Identifying and preserving high-water mark data". The manual is available at: https://pubs.er.usgs.gov/publication/tm3A24.
The U.S. Geological survey maintains a national database at https://water.usgs.gov/floods/FEV/ that includes high-water mark information for many flood events, and local U.S. Geological Survey Water Science Centers can provide information to interested readers about participation in data collection and flood documentation efforts as a USGS volunteer or observer.
