The State of UK Waters
- Only 14% of English rivers meet "good ecological status" under the Water Framework Directive. That means 86% of our rivers are failing basic environmental standards.
- Sewage discharges: Water companies discharged untreated sewage into English waterways over 400,000 times in 2023, totalling more than 3.6 million hours of spills.
- Agricultural runoff: Diffuse pollution from fertilisers, pesticides, and livestock waste remains the single largest source of river pollution, driving eutrophication and algal blooms.
- Monitoring gaps: The Environment Agency's monitoring budget has been cut by over 75% since 2010. Citizen science is now essential to fill the data gap.
What Your Data Does
- Builds the evidence base: Every observation is GPS-tagged, timestamped, and stored in a structured database. Over time, this reveals pollution patterns, seasonal trends, and problem hotspots that would otherwise go undetected.
- Links water quality to biodiversity: Your water observations are overlaid with species records from the same catchment. Does fish diversity drop when turbidity spikes? Does invertebrate richness correlate with water clarity? This cross-analysis is what no other UK citizen science platform can provide.
- Catchment-level analytics: Hydroscape's BioMapper tool aggregates your reports by geographic zone, calculating mean clarity, pollution frequency, flow patterns, and ecological health indices — transforming individual observations into catchment intelligence.
- Supports regulatory action: Structured, verified data carries more weight than anecdotal reports. Your observations can support Environment Agency investigations, planning objections, and conservation designations.
What You're Observing
- Visual indicators: Clarity, colour, surface conditions, algae, foam — these are powerful early-warning signals. A river turning milky-grey, a pond covered in blue-green algal scum, or a canal with an oil sheen all tell a story about what's happening upstream.
- Odour: Sewage and chemical smells are strong indicators of acute pollution events that may not yet be visible in the water itself.
- Flow and level: Abnormal flow rates or water levels can indicate upstream abstraction, dam releases, or drought stress — all of which affect water quality and aquatic life.
- Pollution evidence: Dead fish, active discharge pipes, sewage fungus, litter accumulation — documenting these with photos creates an evidence trail that the EA can act on.
The Hydroscape Advantage
- No login required: Submit a report in 60 seconds from any device. No account, no registration, no app store download.
- AI-verified photos: Every photo is analysed by Hydro-Vision AI to detect water condition indicators — turbidity levels, algal presence, pollution signatures — adding a layer of automated verification to your observation.
- HydroProbe ready: If you have a HydroProbe Bluetooth sensor, connect it directly from this form to auto-populate quantitative measurements (temperature, TDS, conductivity, turbidity, pH) alongside your visual observations.
- Species + environment: Hydroscape is the only UK citizen science platform that combines quantitative species biodiversity data with water quality observations in a single integrated ecosystem.
- Open data: All observations feed into the public dashboard at hydroscape-group.co.uk/public_dashboard — viewable by anyone, no login needed.
Active Pollution?
If you're witnessing active pollution — sewage discharge, dead fish, chemical spills, or discharge pipes running in dry weather — don't just report here. Call the Environment Agency 24/7 incident hotline immediately:
0800 80 70 60
For life-threatening emergencies, call 999. In Wales, call NRW on 0300 065 3000. In Ireland, call EPA on 1850 365 121. The form will detect your location and show the correct authority automatically.
