LADWP – Owens Lake Dust Mitigation Controls Project

Owens Lake’s ponds, lateral shallow flood, and managed vegetation require water for dust mitigation in compliance with environmental mitigation agreements. The Lake’s water use fluctuates throughout the day due to automated schedules that run over 150 shallow flood laterals and over 50 managed vegetation blocks. There are also numerous ponds filled by large submains throughout the Lake. Water supplied for these different dust mitigation measures is supplied from the Los Angeles Aqueduct and the Lower Owens River Pump Station (LORPS) through a mainline pipe that transects Owens Lake. ProjectLine developed control strategies for the implementation of a new Lake Flow Stabilization and Pressure Control tool. The strategies were implemented on Allen Bradley ControlLogix PLCs communicating via Controlnet. ProjectLine’s scope included developing bench and on-site test procedures, and assisting with operator training. ProjectLine was a subconsultant to CDM for the project.
