The Carp lakes
The Graviers consists of two Gravel pits, located in the Cote d'or region of France, not far from Dijon.The Main lake is around 25+ acres, and was extracted back at the end of the 1970's early 80's, and the Long lake is around 5 acres and was extracted in 2001.
The Main lake
Depths of around 10/11 feet, and an excellent water quality, the Main lake has already produced some remarkable fish. The Long lake is slightly shallower and is now also producing some quality carp too.
The age of some of the Main lake Carp has been determined via professional scale readings from an English University. Amazing results have shown incredible growth rates, for this relatively "new" lake, especially when compared to other waters from other areas in France.
It just goes to show that the age of a water has no real influence on the growth capability of the fish within it, in fact, a "new" water with the right make up, is probably a far more beneficial environment as it's natural resources have not been exhausted.
The extraction of the Main lake started back in 1979, when the local community decided to exploit the gravel deposits found in the area, which were used mainly in the construction of the auto route. The lake was in fact formed in 3 separate stages, over a period of around 11 years in total, with completion being around 1990 when the lake finally acquired the distinctive shape it has today.
The pits in the area were extracted via the use of large 360 diggers as opposed to drag lines which tend to be used on the larger extractions. The gravel was transported by means of conveyer belts to a centrally located depot, where it was cleaned, graded and stocked.
Strict regulations determined the exact volume of gravel extracted in any of the pits in the region, which in turn dictated the size and depths of these gravel pits as we find them today, and is also the reason the lakes in the area tend not to have many of what anglers term as features, i.e. bars, holes, plateau's etc.
By the end of the 80's the lake had become very popular with the people of Dijon for swimming and sunbathing, probably because of the very high water quality. It was about this time in fact that the original restaurant was built on the lake, and the owner created his business based on the popularity of the aquatic activities, introducing Pedalos, boats, swimming, Donkey rides, diving board, table tennis, etc. A thriving business at the time, but was soon to be affected by the changes in the law concerning public safety. Eventually, all the other activities ceased, and only the restaurant remained open.

It has proved impossible to find out exactly at what stage the lake was originally stocked, but, based on the age of the Carp from the scale readings taken, we presume the fish were introduced once the lake excavation had been completed, around end of the 80's to early 90's.
The Carp and other species such as Roach, Rudd, Pike and Zander, were most probably supplied by a local Piscaculture to the local communities, who were in fact responsible for stocking the pits they had created. The carp stock would have been bread, and grown on by the Piscaculture in his local etangs, and probably sold on after 3 seasons.
The stock of Carp at the lake has not been added to by myself since arriving here in 2001, and as the lake seems to be producing new carp each year now, it will probably never be added to.
STOP PRESS! November2017, I have now added a handfull of scaley mirrors, to boost the feeding..lets see what happens!
Recently, I have been lucky enough to acquire video footage of the Carp at the lake prior to my arrival here. It's amazing to see all of the fish at considerably smaller sizes than they are now... it's evidence of the weight gains that some of the fish have shown since our fishery management program was applied.
