The lake varies in depth from two feet to twelve feet. There is a small amount of weed growth in the margins and little elsewhere. The lake is well known for its catfish stocks which currently reach 55lb. There are numerous fish in the 20/30 and 40lb range. The lake also contains a good head of carp, some of which have been caught close to thirty pounds. Recently the lake was stocked with fast growing Simmonds mirror carp at 4lb-5lb. Last year some of these fish were caught at 15lb-17lb which indicates an impressive growth rate.
There are large stocks of roach and bream in the lake. Pike are present but do not grow to any great size. Anglers may park along one side of the lake and walk a short distance to their swim. Do not park close to the Grundfos Pumps gates and block them!! Anglers wishing to night fish must apply for a place on a night syndicate. Members must leave the water in the evening at the time stated in the club membership booklet. Three rods may be used on this water. There are no bait bans or tackle limits. We do suggest that anglers fishing for catfish use at least 15lb line and appropriate rods. Rackley Hills lake is owned by Leighton Buzzard Angling Club. The lake is open from May 1st to March 15th.
