Hunstrete is the right spelling for a start
I have fished there but quite a few years ago. I know some of the guys fishing there now and the silt is not a problem at all. Its not that deep that leads and rigs sink into it so don't worry about that.
It does hold quite a few 20s and there maybe one 30lber in there. I say maybe cos there are question marks over how the fish was weighed. I heard it went 29lb 15....... the bloke who caught it claimed a weight of 30lb and ounces. Either way, its a nice fish and I would be happy to catch it at any size.
Tips I can offer....... hmmmm where to start
I would guess the pads are maybe just starting to shoot up from the lake bed. Have you dragged a lead and felt the roots?
One good swim where fish used to hang out this time of year was the double swim on the left hand bank.
Also, don't ignore the very top end of the lake. Most cant be bothered to walk that far but there used to be a coupl of nice over hanging trees to cast to from the left hand bank again.
If the wind is pushing towards the carp park, then I would try the swim next to the toilet. Always turned up a fish or two on the right wind.
Bait wise, try get onto a good quality fishmeal. There was a couple of brothers that really filled the place in with fishmeal baits a couple of years back and they caught very well indead! From what I hear, fishmeals are still the dominant and going bait
That should keep you going for starters
Let me know how you got on today.
Good Luck for the rest of the week
ps. dont be put off if the weather turns a bit colder, like it is due to. It used to fish really well in cold conditions. These brothers I mentioned only used to fish winters and emptied the place
