Overview

• The Edersee reservoir stands at roughly 19.5% of capacity after months of below-average rainfall in its Werra, Fulda and Eder catchments.
• Managers have reduced releases to the six cubic meters per second minimum, down from typical 20–30 m³/s, ending regulated flow support for the Oberweser.
• Low drafts have halted commercial navigation on the Weser and constrained water sports, with only muscle-powered craft still able to operate.
• Lakefront businesses, including surf and sailing schools, report up to 50% drops in revenue as steganlagen dry out and tourist activities stall.
• Regional stakeholders are demanding water management reforms to address worsening shortages, with forecasts predicting continued low rainfall.
