Characterized by its shingle terrain, The Warren, Hay On Wye is a designated bathing area in Powys, Wales. Environmental sampling at the site provides an annual water quality classification of Sufficient. First designated in 2025, this location remains a popular destination for recreational visits.
The shoreline consists primarily of shingle. Sediment type dictates underfoot comfort, wave energy absorption, and the water's clarity when currents stir up the seabed.
Water complies with minimum legal safety limits. However, higher bacterial levels are occasionally recorded, indicating moderate vulnerability to runoff.
Bacterial levels are highly susceptible to storm runoff. Heavy rainfall in the local catchment is likely to trigger storm overflows and agricultural runoff, rendering the water temporarily unsafe.
Tested weekly by the Environment Agency England for bacteria levels (E. coli & Intestinal Enterococci) between May and September.
Monitored as an inland river bathing water. River sites are heavily influenced by upstream rainfall, agricultural runoff, and storm overflows, with water flow changing quickly after rain.
Unknown is the regional utility responsible for waste water treatment, sewage infrastructure, and storm overflow management in this catchment area.
Officially designated as a protected bathing water site in 2025. This designation mandates regular public health monitoring.
Governed under local district sanitation and environmental safety regulations in the Powys area.
