A. Reducing reservoir levels is challenging due to several key factors:

• Weather patterns and inflows: Wet Sleddale’s catchment area (1,848 hectares, including How Gill, Thornship, Keld, Lanshaw, Tailbert, and Swear Gill) feeds into the reservoir, meaning levels are heavily influenced by rainfall. If inflows are high, levels may rise despite management efforts.
• Water supply and environmental regulations: The reservoir supports downstream river habitats, with a compensation flow of approximately 35 Ml/d during November and December. Releasing excessive water could disrupt natural watercourses and affect ecosystems.
• Flood risk and operational considerations: Wet Sleddale provides regulated releases to the River Lowther to help maintain ecological balance. If too much water is released at once, it could increase flood risks or reduce available water during dry periods.
