They make the decision by Sept 1

Here is all of the details...

Article 403. Conditional Fall Extension. The licensee must initiate the following
monitoring process on an annual basis to evaluate implementation of the Conditional Fall
Extension. The flood control curve, identified in Article 402, must be at elevation
491 feet mean sea level (msl) from September 1 to October 15 (i.e., the shaded zone in
Figure 1, Article 402), provided that the following hydrologic and operational conditions
are met:

1. Lake Martin is above its operating curve during September (487 to 488.5 feet
msl);

Project No. 349-173 - 83 -
2. the rolling 7-day average total basin inflow (i.e., the average of the total daily
basin inflow for the previous 7 days recalculated on a daily basis for a given period
of time) on the Tallapoosa River, calculated at Thurlow Dam, is at or higher than
the median flow (i.e., the median of the recorded daily flows over the period of
record for the particular day of interest);
3. the rolling 7-day average total basin inflow on the Coosa River, calculated at
Jordan Dam, is at or higher than the median flow; and
4. the elevations at the Weiss, Neely Henry, and Logan Martin developments on the
Coosa River and the R.L. Harris Project on the Tallapoosa River must all be
within 1 foot of their respective operating curves.

No later than July 14 of each year, the licensee must monitor conditions daily.
Beginning on September 1 of each year, once the four conditions are met, the Conditional
Fall Extension will be implemented and continue to October 15. The normal reservoir
drawdown to the winter pool must begin October 15.

The licensee must file a report with the Commission by December 15 of each year
if the above conditions were not met. The report must include a description of the daily
hydraulic and operation conditions that prevented implementing the Conditional Fall
Extension. In addition, regardless of the outcome of the evaluation, the licensee must
post, from July 15 through October 15, weekly reports on its website providing (1) the
posting date; (2) the lake level on the posting date; and (3) from (a) July 15 through
August 31, an estimate of the likelihood that the Conditional Fall Extension will be
implemented that fall, (b) September 1 to October 15, a statement of whether or not the
Conditional Fall Extension is being implemented, and (c) September 1 through
September 30, an estimate of the likelihood that the Conditional Fall Extension will
continue to be implemented to October 15.
