The first Habitat survey of four planned on Losis River has been carried out during 19-21 October 2020  Hydrological measurements and river habitats mapping were conducted downstream Grantini  and Lejnieki HPPs operated in cascade regime. In accordance with work plan it has to be the survey in presence of minimum flow in the low flow period. However during the survey downstream Grantini HPP water was released through HPP turbines. As a result habitats were mapped for average water discharge. In a next day  measurements and habitat mapping have been repeated downstream Grantini HPP for low flow conditions.

 

On  Ciecere River the  Habitat survey has been carried out  11-13 November 2020. Hydrological measurements and river habitats mapping were conducted in three river stretches downstream Ciecere, Dzirnavnieki and Pakuli HPPs. It was first Habitat survey in presence of minimum water discharge in low flow period.
