Year by year

Scottish Water's published data for monitored overflows (number of overflow events; Scottish Water does not use the 12/24-hour count). 2026 is our own running count, the same way, from the live feed since 28 February (when we began keeping every discharge it reports) — so it can only be lower than the full year. The official figure is published next spring.

"No data" means the monitor was not working or not required to report that year — not zero. Scottish Water counts each overflow event; England and Wales count 12/24-hour "spills", so these numbers are not directly comparable with English or Welsh overflows.

Other outlets here

Scottish Water runs 2 other overflows within 300 m that also discharge into Un-named Tributary Of Kirk Burn. They share the sewer and the storm, so one outlet's figures are only part of what reaches the water.

Discharges we have recorded

140 discharge periods since 1 Jan 2025. 134 of them come from Scottish Water's own event-duration-monitoring records (published by the company, Jan 2025 – Dec 2025); the live feed adds anything after that. The official annual count is the figure to quote.

Nearest live rain gauge: Merton Bank Lochmaben, 4.6 km away. Brown shading = when this overflow was discharging; ▼ = a discharge start.

Overflow shading is a timing match, not proof of cause — heavy rain and spills share a trigger. Times come from the water company’s event-duration monitor (site status only; no discharge volume is published).
