In the early followingnoon, several people, including the La Roche-en-Ardenne fishing company, alerted the municipal authorities regarding a problem at the dam. The water level had then dropped by several tens of centimeters.
“I was alerted before 2 p.m., explains Mayor Guy Gilloteaux. I was told that the water level had dropped fifty centimeters. But when I got there, the body of water was completely empty. You should know that the water is always fixed at the same level using a mechanism that includes weights and counterweights. It turns out that the cable of a counterweight gave way, we don’t know why. The level therefore fell, which caused a small wave downstream of the dam.
An unfortunate incident, especially for the fish present in the Ourthe.
Downstream fish mortality is limited, but upstream…
If a mobile team went on site for the technical accident, the DNF went on site to assess the fish mortality rate. “According to an initial analysis, this rate is quite limited downstream of the damcontinues the mayor. Upstream, on the other hand, many small fish, alvins, died. The fishing company also moved to try to save some.”
Several pedal boats from a tourism company, located next to the Ourthe, were also trapped, “one of them is broken, says once more Guy Gilloteaux. Regarding the repair work, they promise to be long. We will need a large lifting crane. The water level shouldn’t return to normal for at least a week.”
