Out of season
Weekly sampling and the daily pollution-risk forecast pause on 30 September and resume on 15 May. This verdict rests on the annual classification, live storm-overflow data and rainfall in the last 24 hours.
Storm overflows are driven by rain, so they spill more in autumn and winter than in summer. See every spill happening now across the UK.

Latest bacteria reading
Latest sample · 21 September 2026 · 10 days ago
- E. coli
- 300cfu/100ml
- Intestinal enterococci
- 170cfu/100ml
This is the most recent reading. Sampling resumes on 15 May. E. coli and intestinal enterococci are the indicator organisms used in the official classification.
Classification record, 2015 to 2025
Rated Good in 2015 and Excellent in 2025.
The regulator republishes this every November as a percentile over readings from up to four bathing seasons, so it describes the water's record rather than today. No classification was made for 2020, when the pandemic cut the bathing season short.
Storm overflows nearby
The Environment Agency does not link any storm overflow directly to Henleaze Lake, so there is no spill record for it. There were 268 monitored overflows within ten kilometres in 2025, whether or not they drain here.
