Under Construction

At this point in the project it’s hard to tell what is being restored, constructed, and removed.

The impoundment has a completely different profile. What was once a mostly vertical face now has two sections–a slope (red arrow) and a bench (white arrow). The slopes are stabilized with jute matting and will be seeded with various plantings to help increase erosion and sediment control.
The June 28th DR included a diagram of the stream showing “rock cross vanes” inserted into the banks and across the bed. All but two of these have been installed and are already creating pools and riffles in the downstream flow.
Within the next week to ten days we’ll begin to see more results: the completion of the cross vanes, the removal of existing spoils from the lake bed, and the construction of fish habitat shelves along our berm.
Phil will be taking the PL kids on a tour of the “bottom” of the lake this Saturday, July 23rd at 10 a.m. and describing the lake project from a fish-eye view. This tour is open to children of all ages–feel free to attend (and wear shoes that can take some mud!).
