I wish I could help you with the information you asked for, but I dont know what type of bottom will be found at Lake Pleasent.
But I do know about anchors.... any anchor with pointy thing protruding from it at any angle is subject to being hung up on some bottom structure. if it is simply a mud or gravel bottom, its and easy choice of the type of anchor needed. if the bottom is littered with old stumps, boulders or trash of some type, there is no good answer.
the very best thing that you can do is rig your anchor with a trip line. any anchor can be rigged with a trip line and in almost every case you will be able to retrieve your stuck anchor. but not every case..... I have been hired to dive and retrieve anchors and have found that its very common that when the anchor lands it will slide down the slope and go under an exposed tree root. or be dropped onto a bunch of boulders where the anchor will work its way down in to a hole..... sometimes its not the anchor, but the rode or chain ties itself in a knot around a root or rock as the boat swings.
there is no guarantee that whenever you throw something overboard, that you will ever get it back, but when you have a trip line tied to it as well as an anchor rode, you will always have at least 2 different angles of attack to bring it home.
best of luck....
