During October 2002, November 2004, December 2005 and now again in
December 2007 we have emptied the lake in order to control the
biomass. We also removed 150 male, feral commons in order to reduce
the violence during spawning and allow the large females to spawn
without it involving every fish in the lake and without the
resulting damage. This has, after each drain down, produced massive
weight gains and we expect even better for 2008. With our detailed
records following the 2007 vidange, during which we removed 60,000
unwanted small fish of various species, we can accurately forecast
the likely spring results for 2008 and we are confident that these
will show at least 122 different carp over 30 lb with 35 of them
over 40 lb. On top of these we have exactly 50 catfish to well over
100 lb so we expect 2008 to be our best year ever.

The bed of the
lake is composed of clay and clean, non-smelling silt. The hard
sandy clay shoulders stretch out for twenty to thirty yards and
the water depth ranges from three feet immediately in front of each
swim to six or seven feet in the middle.
The reason that the silt is not the normal black, smelly kind
is that the lake is teeming with blood worms, cadis fly larvae and
literally thousands of swan mussels which are filter feeders and
the reason for “clean Silt”.
