We have included a map of the catchment of the River Otter. More detailed maps showing features such as sub catchments and land cover can be found in the document ‘River Otter Catchment Overview’ produced by the Devon Biodiversity Records Centre. 


Data on the environmental condition of the River Otter including its chemical and ecological status can be found on the Environment Agency’s  Catchment Data Explorer. A map/data showing where discharges of treated sewage and overflows of untreated sewage and storm water into rivers in England & Wales including the River Otter can be found here.


Whilst real time data on water level and flow can be accessed via the Environment Agency’s network of hydrological gauging stations. Further details can be found under Fishing the River Otter.
