Welcome to our new riverfly system, enabling you to view and submit results from our riverfly monitoring scheme. This system currently only hosts the data for 2019 however, we have been undertaken riverfly surveys here in South Cumbria since 2009 (thanks to our fantastic volunteers!). Over time we will be adding the historic data to these maps. All results will continue to be shared with the national riverfly partnership.
Interpreting the riverfly results
Each riverfly survey will give total score for the site, this is based on abundance categories for each of the 8 riverfly groups sampled for. If the total score falls below the trigger level this can suggest a pollution event which is followed up via the appropriate protocol. Please note, riverfly surveys are relatively high level and cannot provide direct information about diversity or abundance but do provide a good indication of any potential reductions in water quality.
