OBSP Data Quality Assessment Summaries are now on the internal page

The OBSP has created several different summaries over the years. Currently the OBSP is publishing periodic data quality assessment summaries. The former summaries were called Quarterly summaries, Cumulative Summaries and Corrective Action reports and all can be found at the OBSP archived summaries link below.

The charts and data that you might secure from this U.S. Geological Survey (USGS) web page (identified as "OBSP") have not received official USGS approval and as such are provisional and subject to revision. The charts and data are released on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from its authorized or unauthorized use.
