This has been designed, and needs to be installed.  It will be invisible from the surface except during operation.

Leaking Box, Security, Safety, and Broken Windows

There is a massive leaking from rotten boards below the powerhouse.   The whole set of boards below the powerhouse needs replacing.

The windows are smashed and need replacement and metal screens. 

Security is inadequate as kids can climb onto the site.

Currently, Avery is generating about 1.42 GWH per year on about 10 feet of head average.  There are two large Flyght turbines - with a total capacity of about 450 kW.  They each pass roughly 250 cfs at 10 feet of head. 

Currently, there is a large amount of work to be done at the site including extensive dam repairs, trash rack replacement and repair, a new control system, utility required upgrades and changes in the operating computer to better control the crest gates.
