Dam Inspection and Maintenance 2013

• Letter to Town of Woodboro Supervisor

 

 

 

In 1989, the town contracted with Del-Mar to repair the Hancock Lake dam. See dam map below:

 

As per Board Minutes dated May 1991, the lake was lowered prior to repair so Del Mar put in an extra stop board. This raised the lake to a level of 1517.65', 3.5" above the 1517.34' level the DNR stated it should be at. The town then removed the top 8" stop board and replaced it with a 4”x4" stop board. This board is still in place. The 2002 Inspection Report places the benchmark on the dam at 1521.16’. Currently the lake level is approximately 4' below the bench mark 1521.16'-4'= 1517.16'. Subtracting the current level from the DNR level: 1517.34 - 1517.16 = .18'. This is 2.16” lower than the DNR level.
