CEO Update 6/11

[Phil Lilley]

Here is the latest for the 4 lake system.

Beaver Lake is passing inflow with full power today; the gates were closed
at 9am. Beaver will double the normal minimum release tomorrow and then go
to minimum release on Monday. Pool should hold near 1129.5 feet into early
next week and as the inflow falls below the minimum flood release there will
be a slow falling trend into the later part of the week.

Table Rock, inflow is holding very high for July. James River at Galena
crested this morning at 42,000 cfs which is about 3.5 times the full power
release. A rising pool will continue into tomorrow with a crest Monday
between 927.5 to 928 feet. Full power (4 units for 24-hours) will continue
tomorrow and be cut to the equivalent of an 18 hour operation on Monday to
try to bring the Table Rock/Bull Shoals balance back to even. Table Rock is
on the lower side of the remaining storage due to the heavy James River
inflow.

Bull Shoals, inflow from the northern edge of the local runoff basin has
been very high with both Bull Creek and Beaver Creek cresting at 20,000 cfs
each. Inflow is falling off quickly and slightly higher releases are
starting today. Targeting a 14 foot stage at Newport due to the greater
than 70% 4 lake system criteria. Looking for a crest Monday btw 692.5 to
693 feet.

Norfork will go higher than 470 by Monday. Releases are being held to
minimum flood amount due to the 3 lake (Beaver, Table Rock and Bull Shoals)
percent full (78%) versus Norfork percent full (52%) well out of balance.
Bull Shoals will get priority on downstream channel capacity.

Several people are asking why we are not releasing more water with the lake
rising. The dams are restricted on what we can release downstream due to
regulating stages. The regulating stage this time of the year is 12 feet,
however since our storage capacity is more than 70% utilized it is now
14-feet. Once the lakes crests hopefully this will help is evacuate the
water for the reservoirs in a more timely manner. Table Rock releases will
be based on what Bull Shoals can release into the White River while dropping
its pool and maintaining a balanced storage capacity with Table Rock.

thanks Phil for the update I appreciate it

By the title of the post, I thought OA was changing hands. Glad to see it isn't.

I'd change the title but your post wouldn't make sense...
