DCYC Amateur Naturalist Report

DCYC Amateur Naturalist Report for June 7th

The killdeer shore birds are nesting again.  Avoid the area near the cone on the high road for a nest there.

We have new guests on the property — a Baltimore Oriole family!!  These birds build nests in the trees thankfully.  Look for a bright orange and black bird about the size of a mockingbird, coming and going from the end of a lower branch on the road side of the first large tree. That’s the male.  Female similar but not as bright. Yes, it looks just like the baseball team colors and logos.

regards,
John

Delivery & installation of Docks 4 & 5

GREAT NEWS

Please know docks 4 & 5 are being delivered so we have lots of trucks and equipment coming and going.

If you do come to the club, please  know it’s a CONSTRUCTION SITE and be careful and keep out of the way at least until all the dock material is delivered.  If you must come, please park in the SWC near the pool (where the camper spot is) to leave plenty of room for big the trucks.

The end is near !!!

Thank you,

James Hankins, Vice Commodore

 

Flooding after recent rains

From our caretaker, Mark Blanchard:

“Parking lot quickly filling up with the lake again. Crane pad is underwater. I am not sure what to think normal Lake level really means. I want to personally thank all of you that showed up yesterday to get the waterfront ready for the rising waters. The show of force made quick work and got the waterfront ready for the Impending flooding. I appreciate your time and effort to make it happen. Thank you all.”

Dock Update per the Harbor Master

Boat moving and re-locations have stabilized for now. If you have a boat in the water, you should find it in your regular slip or in a borrowed slip or still on a mooring.
CHECK ON YOUR BOAT
Expecting rain in coming week.
Ramps to docks have been installed permanently.
New dock 4 and dock 5 install starts at end of March. Be prepared for club disruption like before.
Fire extinguishers, safety ladders and throw lines coming soon.


Time to clear Dock 4

ATTENTION ALL BOAT OWNERS: 

All boats have been moved off of Dock 4, to prepare for the removal and demolition before March.

1)  If you own a slip on Docks 1, 2 or 3—your boat is in its new home or is still on a mooring buoy. If not, contact the Harbormaster by email.

2)  If you own a slip on Docks 4 or 5—your boat is likely on Docks 1-3 in other slips or still on a mooring buoy.

All boat owners—please check your boat and make sure it is secured in place.

3)  What remains on Dock 4 is dock boxes, hoists, extension cords, chains for dock lines, etc.  These need to be removed immediately, as the destruction of dock 4 is ongoing.

4)  Dock lines—the club purchased 3 strand nylon line in bulk, for dock lines to help with the move.  The Harbormaster will be taking a “census” of the dock lines in a few weeks.  If your boat is “home” in the final slip location and you continue to use these lines, there will be a one-time charge to members of $35 to recover the actual cost of the line (approx 100 ft of line per boat). Boats in temporary homes are not involved at this time.   Feel free to “buy” the line this way or replace it with your own dock lines.  Returned club dock lines can be coiled and left for the Harbormaster at a common location.

Thank you,
John Lusk
DCYC Harbor Master


 

Docks 1, 2 and 3 are now in place. Boats are moving in……


All three docks are now in place and they look and feel great, based on many member comments.

There are slight adjustments in the slip assignments, due to dock design and to clean up of the numbering system.

Check your new slip number here, at the Members Only page (login required).

http://dcyc.org/Members_Only

You may now move into your new slip, if you have a slip on the first three.  Either use your own dock lines or prepare to pay the no-profit cost of our club-purchased lines. Cost of these 1/2″ 3 strand nylon lines are $0.35/ft ($0.42/ft for new 5/8″ rope).  Dock savvy folks will realize that this is cheaper than pre-made commercial dock lines. Important note — the connections are lines only.  There are no chains, shackles, chafe gear or other improvements.  While sturdy, these lines should be considered temporary. Please check on and improve your boat soon.

If your boat has been slipped on Dock 4 or Dock 5, it may be moved to unused slips on Docks 1-3 at any time.  This is to enable the demolition of the old docks.

There are exceptions for boats normally docked on the south side of Dock 1.  Contact the Harbormaster if there are questions.

Docks 4 and 5 will be installed in April.


 

Update on the Dock Construction

Construction of Dock 3 is nearly complete. It will join its brothers Dock 1 and Dock 2 within days.

The harbor focus will now change to:

  • more demolition of old docks
  • preparing for electrical and water outlets on all docks
  • preparing for the installation of Dock 4 and Dock 5. Recall that the installation is scheduled for late March.

When (not if) the water level reaches 524′, we can complete the attachment to the lakewall and addition of ramps. Projected at Feb 10-20 timeframe.


 

Dam Failure Potential

Looking for some light reading for your leisurely weekend?

“Even before last spring’s rains, the Lewisville Dam was listed by the Corps as the eighth-most-hazardous in the country. Recent rains have made it worse, the Corps says.

The dam is so unstable now that the Fort Worth District is considering asking Corps headquarters to upgrade its risk classification to the highest: “critically near failure” — that is, “almost certain to fail under normal operations … within a few years without intervention,” according to a Corps document.

…..

Only 34 miles upstream from Dallas, the Lewisville Dam holds back 2 million acre-feet, or 2.5 billion tons, of water when the lake is full. If the dam failed, the magnitude of all that water unleashed from Lake Lewisville down the Trinity River would dwarf the worst dam disaster in American history.”
