Waterbase - Biology in lakes (3 tables)

Data Table

This page was archived on 07 Jul 2014 with reason: Other (New version data-and-maps/data/waterbase-lakes-10 was published)

This separate dataset contains data for the biological quality elements (BQEs) phytobenthos and macroinvertebrates from WISE-SoE lake monitoring stations. The data are reported as ecological quality ratios (EQRs) (for more explanation, see illustration in additional information part) together with information on the national classification systems for ecological status. The dataset is a result of the first regular data flow for Biological elements in rivers and lakes (2011) and it is the first time the biological data are published in Waterbase. In the next updates the data will be published in one dataset together with the other Waterbase lakes data.
