Hydrological study for SSSI water level remediation.
Lee Valley Regional Park Authority seeks a contractor to conduct an in-depth hydrological study at Cornmill Meadows, Waltham Abbey, focusing on the Cornmill Stream and Old River Lea SSSI, which is designated for its dragonfly and damselfly populations. The study must assess causes of falling water levels threatening these species and inform remediation. It should also support monitoring needs of a neighboring project at Royal Gunpowder Mills addressing the Waltham Abbey SSSI. The work includes understanding water flows, future water management, and extreme climate conditions. No specific qualifications or set-asides are mentioned.
