Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.
Scour hole elevation is currently labeled as being referenced to NGVD 1929; however, the data is referenced to NAVD 1988. We have requested a new parameter code to fix this inconsistency and will make the necessary changes once the parameter code is available.
