Yes — there are several online resources you can use to monitor

UK reservoir water levels, from national-level aggregates to regional and even some individual reservoir data. Here’s a structured set of options you can explore:

⸻

🌍 **National / Cross-Region Reservoir Monitoring

🛰️ 1. Environment Agency Hydrology & Water Data Portals (England)
• Hydrology Data Explorer – a portal for live and historic hydrometric data including flows and station data (not always reservoir specific, but often includes related metrics). 
• Hydrology Explorer – data.gov.uk version – lets you filter by water station, name, river, etc., and may include reservoir stations if available. 
• England Water Situation reports – monthly summaries include reservoir stocks for England as a whole and often by region. 

⚠️ These are usually focused on England rather than the whole of the UK, and reservoir data are often part of broader hydrological metrics (river flows, soil moisture, groundwater etc.). 

⸻

📊 **Regional / Water Company Specific Reservoir Levels

Many UK water companies publish current reservoir levels for their service areas — usually weekly or monthly updates:

📍 England & Wales
• United Utilities – Reservoir Levels: weekly reservoir level updates for key reservoirs in the north-west. 
• Yorkshire Water – Watsit report & Reservoir Data: open data on regional stocks and water resources, including reservoir storage vs historical trends. 
• Bristol Water – Reservoir Storage Levels: snapshot of major reservoirs like Chew Valley and Blagdon. 
• Southern Water – Reservoir Levels: weekly updated levels with graphs and current vs long-term averages. 
• Southeast Water – Reservoir Levels: shows levels at major reservoirs such as Arlington and Ardingly. 
• South West Water – Current Reservoir Levels: overview of levels in that region. 
• Anglian Water – Water Resources Monitoring: includes data on reservoir stocks as part of regional water resources. 
• Northumbrian Water – Reservoir Stocks Tables: current stocks and comparison with average for the time of year. 
• St. Water (Severn Trent) – Reservoir Levels: list and breakdown of storage across their reservoirs. 

💡 These pages often provide weekly snapshots of current reservoir levels expressed as a percentage of capacity, and sometimes include simple graphs. 

⸻

🏙️ London Specific
• London Reservoir Levels dataset (data.london.gov.uk) – daily records (as percentage of usable/deployable capacity) for reservoirs serving London (Lower Lee & Lower Thames groups). 

⸻

🇬🇧 **Scotland & Other UK Nations

🇬🇧 Scotland
• SEPA Water Levels Platform: water level data, including river/sea gauges and related hydrology (although not a dedicated reservoir dashboard, it’s the official Scottish Environment Protection Agency source). 

🇬🇧 Wales & N. Ireland
• Dedicated reservoir dashboards for Wales or Northern Ireland vary by utility and are less often centrally bundled; checking Welsh Water or NI Water official sites is useful for local data.

⸻

📦 **Raw/Open Data Sets
• Stream Water Data Portal – datasets with reservoir storage measurements for some water companies (e.g., Yorkshire Water, Southern Water). 
• UK Water Resources Portal (NRFA/CEH) – real-time and historic hydrological data, which may be used for research or building custom monitoring (including reservoir stocks where available). 

⸻

🧠 Notes on Use
• National aggregates (like Environment Agency reports) often show % full for England as a whole rather than specific reservoirs. 
• Water company pages are usually the best for individual reservoir data within their service areas.
• There isn’t a single UK-wide interactive dashboard publicly showing all reservoirs in real time — you typically need to consult multiple company or national data sources.

⸻

If you want, I can share direct links to the most useful dashboards or datasets for your specific region of interest (e.g., England, Scotland, or a particular water company’s supply area).
