How many years would it take before we would have to dredge again?

It is possible to estimate this, based on past history of how many years it took to fill our impoundment to the present level of silt.

Dr. Jeff Thornton (formerly with SEWRPC) arrived at an estimate of 20+ years, without which he would not have approved our dredging project.

Independently, Dr. Andres Peekna (Innovative Mechanics, Inc., currently a WWMD Commissioner) arrived at a best estimate of approximately 30 years. These two estimates are consistent.
