1987 Water Level Calculations

High and low levels for the 1987-1986 season are calculated using a permitted dock installed and photographed at that time.  These pictures and current measurements give us the following lake level measurements:

Dock A: October 1986 - low water

Permitted construction of Dock A in 1987.  Dock A later had a 12’ extension added to it so that it would reach past the rising shoreline.  This picture shows the dock without the 12’ extension and the 12’ ramp. The beams that lay on the piles are 6” square.  The piles stick out 12” based on the beams as a reference.

Dock A: March 1987 – high water

At high water 6 months later the water barely passes the original edge of the dock. Space can be seen under the dock and under the cross beams. Based on the crossbeams I estimate the piles still stick up 6” and the waterline is 2’ past the dock.  These are just estimates though and are not critical.

Dock A: July 2017 – Low Water

This picture at low water, includes the 12’ dock extension.  Low water is about 1’ behind the horizontal wood barrier next to the cattails.

Dock B, Dock C underwater – Dec 2017


Dock C is higher than dock B which is higher than dock A. All of these docks are underwater. The one visible dock sits on spacers added later to lift the dock, otherwise, it would be underwater as well.

Dock A, Dock B, Dock C underwater – Jan 2018

Again, all these docks are underwater. Notice the water line near Dock A is past the 12’ extension and extends past the 12’ board by another 5’.  Assuming the high water was 2’ past the initial dock end, this new high water line consumes 26’ of shoreline. 

These docks stay underwater into May and June unless the levels are dropped by disturbing the dams.
