Dear Gary:

I received your Canton Lake Water Level Management Plan on September 4th. It is a beginning but it still needs work.

Your plan should tell an uninstructed person, say a Canton Selectman, what legal water levels must be held and when. Quote the exact wording from the order. It should indicate how that can be done e.g. if you open 1 gate 2' for one day the W.L. in the lake can be expected to drop 1/2 -1-2" whatever. How do you deal with a 2" rain, a 5" rain, an anticipated hurricane due in 36 hours with a forecast 6" or 7" rain.

More names/address/telephone numbers of 1st backup, 2nd backup, 3rd backup, and which selectmen have keys and permission to operate dam during an emergency or anticipated problem.

A detailed sample of your record form(s). How are records kept, so you don't end up with hundreds of scraps of paper/records in a shoebox. Define how frequently water levels will be checked.

You will notify all "priority downstream users" yet a list with telephone numbers is not provided. A backup won't know them. In an emergency they must be at hand-one can't research in the telephone book.

What authority to act do the backup people have? Under what conditions? Anticipated floods?

In our June 24th meeting you agreed to coodinate with the town and complete the plan by September 1st. You haven't. You agreed to provide the name, address and resume of the registered P.E. who would be working with you on this project. You haven't. As part of the agreement to consider yhour dam safe you agreed to carry out the recommendation made by our dam inspector on pages 9, 10, 11 of the December 6, 1985 Dam Inspection Report. You are to have your registered P.E. inspect the dam every 2 years with a copy of the report to be sent to us. Your statement in your plan that "a professional engineer is to be procured" is insufficient and unacceptable.

I am still waiting for a copy of plans to scale showing the dam in plan and elevation views including the new emergency spillway.

I expect you to correct these deficiencies and to submit a complete Management Plan incorporating the items listed above no later than October 8, 1986. If you have questions you may call me at 289-2111

Sincerely,

DONALD L. ANDERSON
