A very picturesque lake fed from Sweatford Water, often crystal clear and with prolific weed growth providing plenty of natural food. A superb shrimp and corixa water with a good hatch of damselfly, dragonfly and mayfly - best dry fly water here at Rockbourne and on a late Spring day you can watch the trout rise and take the mayfly that have hit the waters surface. It has also been noticeable the it is often the brown trout that are the fish that are rising.

There are lots of roach fry in Longacre every year and through the winter months the trout often gorge themselves on the fry so patterns such as appetisers and cats whiskers are an excellent choice. Through the warmer months smaller natural patterns seem to work best, especially for those that like to stalk along the tree lined bank! A floating line is the best choice.
