Water Quality

Overall monitoring result: unfavourable condition. Microbial contamination classified as excellent. Phosphorus content long-term compliant with general requirements, but non-compliant with catchment requirements for bathing areas in 2010. Occasional weak algal occurrence. Frequent transparency limit shortfalls. Mildly elevated chlorophyll-a values with occasional limit exceedances, particularly in 2010. Frequent visible pollution occurrences. Water often unsuitable for bathing for sensitive persons. Increased phytoplankton occurrence, low transparency, occasional microbial contamination increases, and visible pollution occurrence noted.

Risks

Short-term pollution occurrence with flooding risk on the tributary. High risk from diffuse pollution source from the village of Horní Bečva upper part, with wastewater treatment likely insufficient and medium-level microbiological contamination risk. High risk of phosphorus input to the reservoir.
