3d Printing Helps Record Dam Removal

The one constant in nature is change, but sometimes that change is too slow to notice in any one visit. It is with this in mind that I started off on a mission to document the change over time at the Pond Lily Nature Preserve.

 

Pond Lily Dam (spillway) July 2014

 

The preserve is soon to undergo a great transformation. For more than 250 years a dam at the location blocked the free flow of the West River. Recently, through the work of the Connecticut Fund for the Environment and the funding of a resilience grant through the US Fish and Wildlife Service that dam will be removed sometime in 2015.  At first the change will be swift and dramatic. Construction staging will be setup, the river will be diverted to a temporary channel, earthwork and the careful teardown of the dam wall will proceed. When the deconstruction is done we will have a river which has been returned to a state that it has not been for centuries.
