Lake Avalon

Duration:  The lowering of the lake will begin on November 9, 2017.  The lake can be lowered 2 inches per day and should be down 4 feet by December 3, 2017 unless we receive significant rains.  The lake will be allowed to refill beginning on February 15, 2018.  How long it will take for the lake to fully refill is dependent upon the weather.

Target Depth of Drawdown:  4 feet

 Purpose: In order to accomplish the preparatory work for the Beach at Lake Avalon, the lake is required to be lowered by a minimum of 4 feet.  This will allow heavy equipment to have access to the beach area so that leaf matter and debris can be removed and sand placed.  Additionally, recent flood events have made it necessary to remove a large gravel bar that washed in to the right of the boat launch.

Additional wash in areas are a problem at the back of many coves.  Residents have expressed interest in pooling resources to dredge these areas.

Process: No infrastructure is in place to accomplish a drawdown.  Two 8” siphon tubes are used to bring the lake down.


Loch Lomond

Duration:  The gates will be opened on November 13, 2017 and allowed to drop 3 inches per day for 16 days.  Anything quicker would result in flooding of the Scottsdale Golf Course.  Barring any significant rainfall, the lake should be down 4 feet by November 29, 2017.  With a 4 foot drawdown, marina docks will not have to be repositioned.  The lake will be allowed to refill beginning on February 15, 2018. How long it will take for the lake to fully refill is dependent upon the weather.

On a first come first served basis, we will allow lakefront property owners to dock their boat(s) at the marina free of charge while the lake is down.

Target Depth of Drawdown:  4 feet

Purpose: The purpose of this draw down is to provide lakefront property owners ample opportunity to build and make repairs to sea walls and docks.  By posting these plans well in advance, this will give our property owners sufficient time to make plans and hire a contractor.

The concrete spillway is in need of some minor repair due to spalling of the surface and expanding joints between concrete sections.  These issues have been mentioned in recent dam inspection reports.

Recent flood events have caused the deposition of gravel and silt to the west of the Stoneykirk boat ramp.  The courtesy dock at the ramp has a small retaining wall that is about to fall over.  This needs to be replaced.  The Stoneykirk ramp also needs to be extended to correct ongoing washout when boats are being trailered.

The Granton ramp is extensive, but very shallow.  Minor amounts of wash in can create problems for launching boats.  An area to the west of the ramp has filled in and is in need of dredging.  This shallow area can interfere with launching boats and the use of adjacent courtesy docks.  Additionally, many residents along that bank have expressed interest in dredging around their own properties.

Additional wash in areas are a problem at the back of many coves.  Residents have expressed interest in pooling resources to dredge these areas.

Process: Infrastructure is in place to accomplish this drawdown.
