I fished out of Longview (Willow Grove) a few times last year. We just used a normal anchor on my buddy's sled, with no buckets... his is an open boat.

If I were to bring my boat down there I'd use a sea anchor or a couple of buckets while anchored, mine has a big top on it.

To tell you the truth, we had better luck trolling. Everyone trolls on the incoming tide, then anchors up on the outgoing when the current picks up. We trolled both times, and used conventional saltwater gear... flasher and hootchie or spoon. Did OK, got a couple, but no one else was knocking them dead then, either.
