COE Lake Level Bulletin, 6/10/15

[Phil Lilley]

WHITE RIVER SYSTEM. Rainfall across all of the lakes of about 1 to 1.5
inches; 0.7 at Beaver. This has all of the lakes rising again, but all lakes
are rising within expectations...I do not foresee any significant spillway
discharges based upon rainfall on the ground. Inflow into the lakes exceeded
the releases, so all lakes are rising and expect this to continue for a few
days. With the exception of Beaver, we have flood storage remaining in all
lakes.

BEAVER. Inflow went up to 22,000 last night, so we increased releases this
morning to 15,100 dsf, which was about 4000 cfs increase. We plan to keep
this release until Saturday morning, then close the spillway release.
Maintain full power (7500 dsf) until inflow recedes. Early 4-cast: pool
crest at 1130.1 and recede to 1129 by Monday.

TABLE ROCK. Maintain full power release, about 13,000 cfs. Inflow increased
to 80,000 last night and still expect inflow from James River later today.
The pool will rise because inflow exceeds release, but we are restricted by
Bull Shoals elevation so we cannot increase to 20,000 cfs now. Early
forecast expect pool to crest at 926 to 926.5 ft by Sunday.

BULL SHOALS. Restricted by downstream conditions, so it is restricted to
firm power. Inflow was about 67,000 cfs & we are restricted to firm energy
(3750 dsf), so the lake will rise. We will increase releases as soon as
Newport crests and recedes enough to regulate to 14 ft stage. Expect pool to
continue rising and crest at 691.5 to 692 ft early next week.

NORFORK. Restricted by downstream conditions, so it is restricted to firm
power. No opportunity to increase releases because the 3-lake subsystem
(BV-TR-BS) has more flood storage in use, so BS will make the release when
downstream condition allows. Inflow was about 13,000 cfs this morning, and
with restriction to firm power (1,300 dsf) the lake will rise.

The lake forecast may be posted by now, which will give you a 3-day look.


NOTE: 4-LAKE Upper White River SYSTEM STORAGE is currently 71.2% and rising.

Current stage at Newport is 13.14 and rising, NWS forecasting 14.5 peak
stage (12' regulating stage). SWL believes this will be closer to 16 ft as
an initial estimate.

Current stage at Georgetown is at 13.79' and falling (13' regulating stage).
