NMSC volunteers wanted, lake conditions

New Mexico Sailing Club
Still needs volunteers for

Racing this weekend

(And, Gerald is looking for volunteers to help his Scout troop with an Eagle Scout Project this weekend, August 18 and 19. They will be posting signposts for a nature trail)

Helping out at the next work party

Serving on next year’s board of directors. Our commodore, vice commodore, and secretary have expiring terms, three other director terms are expiring, and one director needs a long-term substitute.

Helping out with activities this and next year.

Race on Labor Day weekend.

Participate in the Potluck on the Saturday before Labor Day.

Participate in the ice cream social, dessert potluck, and club meeting on September 2, the Sunday before Labor Day.

Help with Buccaneer Rodeo and racing on Labor Day weekend.
We especially need a mark set boat operator, a chase/safety boat operator, and a skipper that could take out spectators. We could also use someone to sound the horns and help organize the potluck back on land. And, we could use people who know the racing rules for the protest committee/jury. Thanks to Perry for volunteering to be Signaller.

Last weekend we put “Black Magic” back in the water. During the week we attended the RGSC fleet social. The lakes are holding up well and we may be getting some more tropical moisture later on this month.

Elephant Butte Lake, New MexicoFriday, August 17, 2007, 09:00 AM
4,333.72 feet elev. above benchmark
426,384 acre feet
down 0.18' (2.2 inches) and 2,124 acre feet in 24 hours
down 0.52' (6 inches) and 6,194 acre feet in 71 hours

San Marcial Floodway flow at 11:00 a.m. was 36 cubic feet per second (31 to 161 cfs in past 71 hours)
Flow out the dam at 11 AM was 1,420 c.f.s. (1350 to 1440 cfs in past 71 hours).

Comparison to operations plan projections:

Ops plan projection was for 302 cfs inflow, 1,825 cfs flow out the dam.

Ops plan projected lake level for the end of Aug. 16 was 4,332.39' elev., 410,790 a.f.

Ops plan had projected outflow of 1,280 cfs from August 26 to Oct. 13. The lake is 16 inches higher and has about 15,600 more a.f. of water than projected. Although less water is flowing into the lake than projected, less is flowing out at the dam as well.

Maximum projected loss still leaves the lake 27' higher than the lowest level during the 2005 drought.
Projected outflow is 1,825 c.f.s. per day through August 25, then 1,280 c.f.s. from Aug. 26 to Oct. 13

Reality check: The Butte probably won’t go below around 4,323.50 ft. elev. and 314,250 a.f.
