Absolutely!  Hurricane Fran completely breached the dam for Yates Mill, a
millsite since 1756, with the present mill structure partially dating from
1820 with 1860s major revamping.  It provided an excellent opportunity to
observe such a dam in cross section.  It was rebuilt with a concrete core
and faced with stone in order to meet current regulations for dams.

This press release gives contact info at the top.  I would start with
Rebeccah; she can probably get you in touch with the design team and others
with the detailed records.

Wish I could be more help, but I gotta lot to do before I leave for
Providence Monday.

Cheers to all,
