Due to the significant amount of
organic matter
Organic matter, organic material, or natural organic matter refers to the large source of carbon-based compounds found within natural and engineered, terrestrial, and aquatic environments. It is matter composed of organic compounds that have c ...
in the tank (approx. 11.5% of the dry weight of sediment), it emits approx. 400 mg of
methane per area of 1 m
2 (which is approx. 27% of the total amount of gases emitted from the sediment of average 3114 ml m
−2 d
−1). For this reason, is considered an important source of
greenhouse gases emission.
Functions
The tank has three basic functions:
* Retention - during
floods, water on the Vistula River reservoir retains a large part of the floodwaters;
* Energy - on the dam is
Wloclawek hydroelectric power plant;
* Tourism - Lake Wloclawski developed following tourist centers:
Zarzeczewo, ''
Wistka Kings'',
Soczewka,
Murzynowo.
Flood protection
Wloclawek reservoir tank is essentially instantaneous. From approx. 2004. In the event of high water levels acts as a storage reservoir.
Flood 2010
On 17 May at the dam in Wloclawek thrown water (3,000 m³/s), preparing for the arrival of the flood wave. 22 May inflow was 6,000 m³/s, a snapshot already amounted to 5700 m³/s. During the climax assumed dump 6,300 m³/s. May 23, at 14 the culmination wave reached Wloclawek, but the water level was lower than expected initially, due to the rupture of a dam in the town of
Åšwiniary under
Plock iem.
shaft broken in Åšwiniary, 4 thousand. people to evacuate
Flood 2014
During the flood Vistula May 22, 2014 r. To Włocławski Reservoir affect 4900 m³/s, the discharge was at that time 4300 m³/s. As a result, they managed to flatten the wave of flood and reduce the risk of flooding in the lower section of the Vistula.
