Boating safety tips are available from the U.S. Coast Guard.

NOTE: Station Numbers for Iowa precipitation gages have changed (see list).

NOTE: The Iowa Water Science Center has transitioned to a new data management software package. While you may not have noticed this transition, some sites may have problems or delays in being updated. We are actively monitoring these conditions and are resolving them as quickly as possible.
