R655-12-3A. Content of Initial Filling Plans

Initial filling plans should include the following information:

1. The rate, in vertical feet per day, that the reservoir should be filled or drawn down. Instructions on what steps should be taken in the event inflow exceeds the established rate. Rates and criteria can vary with reservoir elevation.

2. The frequency at which the dam will be observed or inspected and who is responsible. A checklist should be provided so critical features are observed.

3. The frequency at which all instrumentation is to be read and how the readings are to be distributed to interested parties. Predicted performance of instrumentation should be included and a reporting procedure established to review unexpected readings in a timely manner.

4. Reference to the Emergency Action Plan should be given so the inspector or engineer understands emergency procedures and contacts to be made when unusual conditions, or possible failure, are observed.

5. A procedure should be outlined whereby the data and observations obtained following the first cycle of filling can be included to supplement or modify the Standard Operating Plan.

6. The Initial Filling Plan should include a requirement that any project features that did not function as designed must be re-evaluated with provisions for mitigation work provided when necessary.
