A narrative summary of this information is utilized herein in reporting the hydrologic
conditions experienced during the reporting water year and for comparing these conditions with
the previous water year thereby giving the reader a general idea of the most recent and previous
hydrologic conditions of the area. The data for Site 11 is incomplete due to construction of the
Cypress Bend Complex, therefore, this station is not included in the narrative summary.
For the fifteen stations having complete records, 55% of the monthly rainfall totals were
below the long term average compared to 70% for WY 05-06 and 45% of the monthly rainfall
totals were above the long term average compared to 30% for WY 05-06. 33% of the annual
rainfall totals were below the long term average compared to 100% for WY 05-06 and 67% of the
annual rainfall totals were above the long term average compared to 0% for WY 05-06.
Noteworthy monthly totals on the high side were nine greater than 10 inches with six
occurring in October 06. The maximum for any month was 15.39 inches at Spillway.
Noteworthy monthly totals on the low side were fifteen less than 1 inch with eleven
occurring in August 07. The station at Highway 59 actually recorded 0.00 inches.
Runoff for the basin was 103% of the average (WY 1961-2007) as measured at the Ruliff
gaging station. Tributary gaging stations near Newton, TX and Rosepine, LA had annual runoffs
of 207% of the average and 127% of the average, respectively, of total annual runoff The peak
discharge for various stations was 17,800 cubic feet per second (CFS) on July 20 at Beckville;
19,700 CFS on July 30 at Burkeville; 10,700 CFS on October 19 at Bayou Anacoco near Rosepine,
LA; 38,400 CFS on December 31 at Bon Wier; 41,500 CFS on October 17 at Big Cow Creek near
Newton, TX; and 58,200 CFS at Ruliff on October 22.
Due to reservoir levels being above 172.50 msl releases totaling 5000 CFS were initiated
through the spillway gates at 1230 hours on July 16 and continued at this rate until 1300 hours on
August 3. The total release during this period equaled 180,208.33 acre feet.
The lawsuits filed against Sabine River Authority, State of Louisiana (SRALA) by
downstream residents alleging damages from the March, 2001 spillway releases and the wrongful
death suit for the death of a father and his son during the same time period is still pending.
Records of the daily readings obtained at 0630 hours by the Toledo Bend Project Joint
Operation reflect a maximum reservoir elevation of 172.51 feet on July 18 and 22, 2007 and the
minimum elevation of 161.25 feet on October 16, 2006. This Reseroir low eleiltion of 16125 is a
new record low since the initial filling of the Reservoir in 1968. Releases from the Reservoir for the
water year totald 3,359,800 acre feet. A monthly summary of contents and key elevations of the
Reservoir as reflected by U.S. Geological Survey records is shown in Appendix B. The lowest daily
mean flow at Beckville was 13 on October 7, with the lowest seven-day mi ninum being 17 CFS on
October 6, therefore, the discharge of the Sabine River at Stateline was not maintained above the
required 36 CFS during the year.
Records for the official gaging stations, as well as other stations partially funded by the
Administration, are summarized in Appendix B. More complete records for these stations are
published in reports of the U.S., Geological Survey.5
