“That is the place saving the Oder begins,” says hydrobiologist Robert Czerniawski pointing at an not easily seen rivulet which falls first into the Drawa river after which into the Oder. The Polish basin of Oder is equipped by ten thousand streams and rivulets like this one.
Just some years again, concrete rings within the now meandering rivulet made positive that “water flowed rapidly and freely, with out the potential for creating any residing situations, like in a canal”, Czerniawski explains. For the reason that removing of the concrete parts and restoration, the water within the rivulet can clear itself and trout has returned to spawn. “Nature makes use of one thing instantly,” Czerniawski doesn’t conceal his fascination. “In addition to, now the water movement is way slower due to the bends”. Which means it stays longer within the surroundings as an alternative of simply speeding in the direction of the Baltic Sea.
The Oder catchment space covers one third of Poland. What occurs in Drawa river or in anywhere in Higher or Decrease Silesia, has an affect on the situation of the complete Oder river. “Due to this fact, it isn’t sufficient to deal with the Oder riverbed solely. It’s as if, when saving a tree, we solely handled the trunk and ignored the crown, leaves, and roots,” explains Artur Furdyna, ichthyologist and the sector coordinator of the mission LifeDrawaPL, the costliest river restoration mission within the historical past of the European Union. The EU allotted nearly seven million euros to create applicable situations for the return and improvement of critically endangered species of fish and aquatic crops and the development of fish passes on the Drawa River. Now, amongst others, salmon, which is an indicator of excellent water high quality, can migrate freely once more.
“We won’t survive with one salmon”
Some native farmers are sceptical about salmon safety within the space. They’ve one other drawback: “the small lakes within the higher a part of the Drawa River are virtually dry”, says Stanisław Baliński, a 74-year-old farmer throughout a gathering concerning the challenges for the Drawa basin. He stresses the necessity to enhance the water degree on one of many lakes within the space. He doesn’t perceive why there’s a scarcity of water in Drawsko Lake District if there’s as a lot rain as all the time.
“Drought can nonetheless happen regardless of the traditional rainfall”, reminds Furdyna. “Our actions, amongst others pumping out underground water to irrigate crops, cut back the absorption.”

Czerniawski, who can also be current on the dialogue, emphasises that we can not solely have a look at our personal yard whereas talking about water sources. If we plan to intrude, we should do it correctly, whereas contemplating the complete ecosystem, as a result of uncoordinated actions will trigger hurt. “We can not simply place a weir or a penstock in the next place and don’t care what occurs downstream”, warns Czerniawski.
The consultants’ arguments don’t appear to persuade the native farmers. They declare that they’re “combating for survival and meals safety” since “we won’t have sufficient with only one salmon.”
Hydrobiologist Tomasz Krepski warns towards such statements. “If we don’t deal with each degree of this ecosystem we can have water that will probably be of no use to us.”
Which meals safety?
Furdyna is questioning which meals safety the farmers from the Drawsko Lake District are speaking about. “Ten p.c of the present manufacturing could be sufficient t…
