Never seen it empty in the 40 years I’ve been a member of the DRAC or Pride.
There maybe some photos at Shardlow Heritage Centre by the Clock Warehouse pub in the village though, from when the gravel was being extracted.
May also be worth a trip to Derby Museum as there is a Bronze Age boat that was discovered in the area during gravel extraction, they may have some photos.
Also on here somewhere, was a thread giving details of the contours, and best areas to fish on the lake.
