Włocławek Barrage and related projects

PROJECT DESCRIPTION:

Wloclawek Barrage was designed by Hydroprojekt and constructed between 1962 – 1970, as the first barrage of the planned Lower Vistula Cascade. For almost 50 years the Wloclawek Barrage has been operating as a single damming structure, without necessary hydraulic support. Working conditions of the facility differ significantly from those assumed in the design. This causes intense, still increasing erosion downstream the barrage.

TECHNICAL DATA:

• earth dam 20 m high and 670 m long
• a 10-span reinforced-concrete weir 200 m wide (excluding pillars) and flow capacity of 11.150 m³/s, equipped in shell structure vertical lift gates (in the years 2004 – 2006, in two spans the flap gates were installed)
• hydropower plant of installed power capacity of 162 MW and average annual power generation of 789 GWh
• navigation lock with chamber dimensions of 115 x 12 m and the designed water head of 12,8 m
• fish passage consisting of 30 concrete chambers in the dividing pillar and 3 rest-chambers with lure-water pipeline
