These are some of the email reports and communications from Scot Evans from Truesdale Lake, James Gorman from Pond & Lake Connection, and others involved with the project. Putting selected parts up here for all to see what some of the discussion and learning is looking like.
Summary: The 6†siphon continued flowing during this last two week period and we requested that P&LC restart both 12″ siphons.
On Wednesday 11/20, a Lake Planning Group Meeting was held with John Bergstrom, Robert & Susan Brown, Rob Cummings, Sue Enos, Scot Evans, Lara Gorton, Stephen Macaluso, and Harold Ossher attending.
James Gorman and crew of P&LC restarted both 12†siphons Friday 11/22 at 10:30 am following the one inch of rain we received two days earlier, where the Lake Gauge started at -2.8 feet and steadily rose 8 inches to -2.1 feet.
With another inch of rain received yesterday, all siphons are flowing and we are currently -2.5 feet below the spillway.

Happy Thanksgiving, everyone!
