Somerset Dam Emergency Procedure
In the event of communications loss with the Flood Operations Centre, the Dam Supervisor at Somerset Dam is to assume responsibility for flood releases from the Dam. Once it has been established that communications have been. lost, the Dam Supervisor at Somerset Dam is to:
• Take all practicable measures to restore communications and periodically check the lines of communication for any change;
• Undertake the actions sel out below to release flood water from Somerset Dam;
• Log all actions in the Event Log;
• Ensure the dam is at full supply level at the end of the event;
• Remain in the general vicinity of the dam while on duty.
The actions to be undertaken to release flood water are:
• If communications with Wivenhoe Dam are lost, the level in Wivenhoe Dam is to be assumed as the level shown on gauge boards located downstream of Somerset Dam.
• The radial gates are to be kept raised to allow uncontrolled discharge.
• The regulators are to be closed if the tail water level exceeds EL 68.60 and are generally kept closed. The only exception to this is if the regulators are used to prevent overtopping of the dam.
• Sluice gates are operated as either fully opened or fully closed. The order of operntion for opening the sluice gates is LMKNJOIP. Sluices are to be closed in reverse order of opening. Any inoperable sluices are to be dropped from the opening or closing sequences. The sluice gates are to be operated in accordance with the following procedures:
o . Case 1 - the level in Somerset Dam is below EL 100.45; or
o Case 2 - the level in Somerset Dam is above EL 100.45.
These procedures are described below.

Level in Somerset Dam is below Sluice gates are to be opened Ilt intervals of not less EL 100.45, Level in Wivenhoe than 120 minutes, provided the number of open sluice Dam is below EL 70.0 and falling. gates does not exceed that shown in the "SOMERSET
DAM - MAXIMUM SLUICE GATE OPENING" table. Once a sluice gate is opened, no further sluice gate operations are to be undertaken for 120 minutes.
Level in Somerset Dam is below Sluice gates are to be closed at intervals of not less EL J 00.45, Level in Wiv~llhoe than 180 minutes. Once a sluice gate is closed, no Dam is below EL 70.0 and rising. further sluice gate operations are to be undertaken for
180 minutes.
Level in Somerset Dam is below Sluice gates are to be closed at intervals of not less EL 100.45, Level in Wivenhoe than 60 minutes. Once a sluice gate is closed, no Dam is above EL 70.0. further sluice gate operations are to be undertaken for
60 minutes.
