NHD Downloadable Products Issue

September 16, 2021

HU4 and HU8 level NHD downloadable products are regenerating more slowly than normal.

Typically, HU4 and HU8 level NHD staged products regenerate by the 10th of each month. However, HU4 and HU8 level NHD downloadable product datasets are generating at a much slower pace than usual. During August, only HU4 products regenerated. HU8 products began regenerating on September 1st and finished on September 13.  We are investigating the issue, but expect that products may continue to generate at slower than normal rates.

Thank you for your patience while we address these issues. If you have further questions, please contact National Hydrography Support.
