Great news for DCYC regarding our Corps of Engineers lease:
Just thought everyone could use a little good news… The lease renewal is up this month. It runs us about 8k per year to lease the property. The good news is the CoE has come back with a 10 year lease for the same money as we are paying now… Maybe they felt sorry for us. Anyway very good news….
And even more good news:

“As of Thursday morning June 18, the DCYC harbor has sustained major damage from tropical storm Bill. Docks 1, 2, & 3 have broken free and blown across the harbor to the southeast shore of our harbor. Many of the boats on these docks have sustained significant damage and a few have sunk. Likewise, many boats on dock 4 have also sustained damage and some are taking on water. Volunteers from the club have made every effort to secure the boats in the most immediate danger. All members with boats in slips on docks 4-6 should make time as soon as possible to inspect their boats and take measures to secure them further. At this time access to any of the remaining docks is limited. Members should coordinate with the Harbor Master before going out to the docks.Please plan on bringing new dock lines with you and please use the buddy system when at the docks.
The Board of Governors will be meeting soon to discuss our options and develop and game plan to begin the recovery process. More information will follow soon.”
Dock 1 broke free earlier this evening. Given the dangerous conditions, there is nothing to be done about the docks or boats at the moment. Check back here for updates from the harbor master.
Quick update from the lake. Surf is up! We’re in the back side of tropical storm Bill and the winds have kicked up to 30- 35 mph with higher gusts. We didn’t get alot of heavy rains and the lake doesn’t seem to have come up much, but more rain is forecasted and as you know lake levels continue to rise for hours after the rain stops. Docks and boats seem to be handling the storm with no apparent damage. Once the storm passes I encourage all boat owners check the status of there dock lines and boats. I will update you all of any changes that occur. I hope this helps. Aloha from the end of the road…

But then there’s Bill:
At the current 534.5′ Lewisville Lake Level, there is 49.5′ clearance.
How did we calculate this? First, we took a look at the NTTA Engineering report, to get the official 52′ clearance above the spillway level, which is at 522′. Then, we subtracted the height of the water above the spillway, 2.5′ (534.5-532).
From NTTA Engineering Report: ” The superstructure consists of 68 spans, each 120 feet in length, and a water craft passage span 360 feet in length. The water craft passage span provides a vertical clearance of 52 feet above the uncontrolled spillway elevation and a 350-foot horizontal clearance between span supports
