Although numerous samples were already taken in the run-up to the season opening on 1 May, which confirmed that the lakes' quality was excellent, the Water Management Administration continues to monitor the situation.
Authorities are mostly worried about the potential rise of blue algae, which often plague the country's lakes during periods of elevated temperatures and high phosphor content. If that happens, it is prohibited to swim out of safety reasons. After the latest samples were taken on Tuesday, they were brought to Belval for analysis.
Last Sunday, 400 guests were recorded at the Baggerweieren, a first success for this year's season. Apart from the known bathing locations, the lake in Echternach could soon be classified as a new swimming lake.
