|Access||All over the year||The best places
Since 1974, when the lake was flooded and was declared as a reserve, numbers have grown sreadily. The lake is so attractive for Cranes that it does have the effect of narrowing their migration front. Its 4800 ha make it to be the biggest artificial lake of France.
"Der" comes from the celtic word : "chêne" which means oak
"Chantecoq" is the name of one of the 3 villages swallowed when the lake has been created. The 2 other one are Nuisement- aux-bois and Champaubert-aux-bois.
The Der is a comfortable and fast access from Paris, England, Belgium and Germany
The filling up of the lake between January and June followed by its
drain (until October) make the landscape and surroundings change.
The best spot to observe birds especially in autumn and winter
From the Chantecoq's carpark, follow the footpath on the right of 'La Maison de l'Oiseau et du Poisson". From the observatory you can observe Ducks, Herons, Cormorants .
C La presqu'île de Champaubert :
The water level stays relatively high the whole year because of a dam separating this basin from the rest of the lake.
Observation of : eiders, velvet scoters, Goosander and smew.
This spot is relatively crowded during summer. Thus, the place is much more interessant in winter : grèbes, divers, ducks...
A excellent spot to watch cranes, ducks, swans, herons, cormorants
