Summary

Agencies must notify the Secretary in writing before building or licensing a dam, naming the site and estimating the area that will be flooded or otherwise changed. For flood-retarding dams under 5,000 acre-feet, or any reservoir under 40 surface acres, that notice is needed only if early surveys or other evidence suggest historical or archaeological materials may be present.

With respect to any flood water retarding dam that provides fewer than 5,000 acre-feet of detention capacity, and with respect to any other type of dam that creates a reservoir of fewer than 40 surface acres, this section shall apply only when the constructing agency, in its preliminary surveys, finds or is presented with evidence that historical or archeological materials exist or may be present in the proposed reservoir area.
