The Big River Watch is coordinated by The Rivers Trust and supported by partners and funding from CIWEM and The Rivers Trust Foundation for Water Research (FWR) Legacy Fund and Catchment Systems Thinking Cooperative (CaSTCo) project from the Ofwat Innovation Fund.

As of 2025, Big River Watch is also partnering with Earthwatch to align the survey dates with the Great UK WaterBlitz.
