Operational Staff are required to carry out duties associated with the management and maintenance of the Lagan Weir, the River Lagan and associated facilities. The Operational Staff will work under the direction of the River Manager and River Warden. As much of the work is river based it is a requirement that the operational staff be qualified in boat handling. 1 of the Operational Staff will be a Senior Operator and 1 will be a Health and Safety co-ordinator. Normally a minimum of 3 operators (boatmen) will be required for duty each day though on occasions there may be a need for 4 or 5 operators especially during special events. Although operational staff will be primarily engaged on river operations they will also carry out maintenance and other work at the weir, the aeration building at Stranmillis, the in river diffusers, fishing stands, pontoons, slipway and safety facilities.
