Comments
Shortly after filling, water in the reservoir became eutrophicated. Furthermore, other extreme water quality problems have been detected not only in the lake water, but also in the river water downstream. There was a high risk to human and environmental health that has hardly been managed successfully. In the absence of better remediation measures, the reservoir was completely drained in 1988 and now operates only as a dry retention basin for flood protection.
