Data includes the water that passes the turbines as well as the water not passing the turbines. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia, Finland and Sweden. The activity was declared as not relevant in Denmark, Germany, Latvia, Lithuania and Poland. Data contains only those hydropower dams that are situated closest to the Baltic coast (less than 40 km), are the first ones from the coast in the river network and have a direct connection to the Baltic Sea trough river. Swedish data is a combination of actual measurements and modelling. Modelled data have been calculated with s-hype2012_version_3_0_0. These data are also presented online at http://vattenwebb.smhi.se/regulations/. Please note that data from 2015 is provisional and may be subject to revisions.

Data from Finland consist only an annual average (monthly discharge average is unavailable). Regarding Swedish dataset, measurements have been done by both SMHI and hydropower companies. Modelled data have been validated against discharge measurements. The dataset was approved by all HELCOM Contracting Parties in the HOLAS II Human activities data review process during first quarter of 2017 after corrections. Dataset updated june 2017, regarding Estonian data. For the index calculation in HOLAS II, a previous version of this dataset was used.
