Why this matters for the Dart: households fix what leaves their own pipes; communities fix the river.
Everything so far has been about your own four walls. This page is about what Dart communities can do together, and it starts from a strong position: this river already has one of the most organised communities in the country.
Know your bathing waters, and use them. The Dart's four designated bathing waters at Steamer Quay, Stoke Gabriel, Dittisham and Warfleet Creek 2 exist because local people campaigned for designation. Designation forces regular official testing and publishes an annual classification, which in turn creates pressure for investment where classifications are Poor 4 5. If your stretch of river would benefit from designation, Surfers Against Sewage publishes a free community toolkit, Protecting Wild Waters, to support groups through the campaign and the application process 68.
Check before you swim or paddle. Two free tools show the river's status in near real time. The Safer Seas & Rivers Service app from Surfers Against Sewage sends real-time sewage discharge alerts and water quality information for around 200 UK locations 69. South West Water's WaterFit Live map shows the company's storm overflows, and whether they are operating, in near real time 74. Why it helps the Dart: informed river users are also the river's most motivated witnesses. How hard: easy, two downloads.
Join the water quality testing effort. Friends of the Dart runs one of the larger community testing programmes in the region, sampling 31 sites across the catchment twice a month for E. coli, in wet and dry weather, alongside partners including the Environment Agency and the Universities of York and Plymouth 11. The data has already identified the tributaries that most need attention 12. You can also train as a Riverfly monitor: the national Riverfly Partnership trains volunteers to sample river invertebrates, whose presence or absence is a sensitive, continuous indicator of water quality 70. For a lighter start, River Action's Test My River guide walks community groups from simple observation through nutrient testing to bacteria testing 71. Why it helps the Dart: regulators act on evidence, and volunteers now collect much of the best of it. How hard: easy to moderate, a few hours a month.
Make it visible. A Yellow Fish stencilling event marks the surface water drains in your town or village with the "only rain down the drain" message, using the national toolkit 15. The Green Dog Walkers pledge (see dogs & the river) does the same social work for fouling 60. Both are cheerful, family-friendly ways to move these messages from the screen to the pavement.
Report pollution when you see it. If you see pollution in or entering the river, dead or gasping fish, or an unusual change in flow, smell or colour, call the Environment Agency's 24-hour incident hotline on 0800 80 70 60 72. Note what you can safely: time, exact location, what you can see and smell, and photographs if possible; charity guidance from the Rivers Trust confirms the same route 73. Ask for your incident reference number and keep it, and follow up if you want to hear the outcome of your report. Sewage smells or overflowing manholes can also be reported to South West Water. Why it helps the Dart: incidents that are reported get investigated, and patterns of reports build the case for enforcement. How hard: easy, if the number is already in your phone.
