ADVISORY #1
The Toledo Bend Project Joint Operating Board met today and approved a temporary lake
level drawdown as recommended by the Federal Energy Regulatory Commission (FERC) for
repair and inspection to the soil cement face of the dam. The recommended drawdown is
expected to be to the elevation of 165' m.s.l., which is 2.58 feet below today's elevation of
167.58' m.s.l. Those areas along the soil cement face that have experienced deterioration due
to wave and weather related conditions will be inspected and repaired to ensure the continued
stability and reliability of the structure.

The drawdown is expected to begin Friday, September 10, 2010 by generating with both
hydroelectric units 24 hours day 7 days week. Without significant rainfall and inflow,
the desired elevation of 165' m.s.l. should be reached in approximately two weeks. The
amount of time required to accomplish the repairs will depend on how many areas may be
identified after the lower lake level is attained.

Since it has been several years since a significant drawdown has occurred, this will be a good
time for shoreline owners to inspect and make necessary repairs to boathouses, piers, retaining
walls and related structures. Construction approval applications for this type of activity can be
obtained from the Sabine River Authority of Texas (SRA-TX) Toledo Bend Division Office (409-
565-2273) for Texas residents or from the Sabine River Authority, State of Louisiana (SRA-LA)
Pendleton Office (318-256-4112) for Louisiana residents.

Toledo Bend Project wants to advise everyone that the Antiquities Code of both Texas and
Louisiana prohibit digging for or removal of any artifacts such as arrowheads, bones or pottery
on public property. For more information on each State's code, or to report violators contact
either:
Texas Historical Commission (512-463-6096)

Louisiana Div. of Archeology (225-342-8170)
(www.crt.state.la.us/archaeology/legislation/chapter_13.aspx)

Once all the necessary inspection and repairs are made to the dam, the lake will be
allowed to return to the regular operating guide as conditions allow. Future advisories will
provide updates on the progress of the repairs.
