Now over 1,500 photos on the river survey map!


The Google Earth file is arranged in layers, so you see an overview, or zoom in to find a tributary

Our dedicated volunteers have been working hard to collect the data that informs our work, researching the best places to implement Natural Flood Management (NFM) solutions in the upper Calder Valley.  Over the last 9 months, they have spent an estimated 1000 hours collecting data at a staggering 1,500 locations along the Calder catchment’s watercourses, taking photographs, and carefully measuring data about channel width and depth to inform our flood modelling work.

We have collected the photographic survey into a Google Earth map, available at: http://slowtheflow.net/river-surveys

All photos are geo-located, so you can take a tour of the catchment from the comfort of your armchair.

The Google Earth photo survey  offers a useful reference, and an insight into just how much of the catchment they have covered so far – it is impressive!

There is still plenty to do, though, and soon we will start building ‘log jam’ leaky dams – if you would like to join our team, please see our ‘volunteers’ page:
