Fish Trap Hollow and Fish Trap Hole

Hollow and pool · left bank · about mile 28.5 · Plate A9

After the long shallow run past Grandma Rocks the river turns sharply right at the mouth of Fish Trap Hollow, which comes down from the northwest on the left. The hollow is about a mile and a third long and drains nearly two square miles. A small spring enters the river from the foot of a small on the left, and John Martin is said to have run a sawmill at the mouth of the hollow.

The names probably recall the fish traps of pioneer days, when, by one account, they were common. Rocks and logs were laid in the river to stop the fish moving upstream, and the water was funneled over the swiftest spot. When someone wanted a mess of spring suckers and redhorse, they set a crate in the swift water above the obstruction. The fish swam over the obstruction into the crate and were trapped, and the crate was taken out and put in the bushes until it was needed again. Missouri’s first full game and fish law, the Walmsley Law of 1905, banned fish traps on most of the state’s waters from July through March, along with gill nets, and trotlines.

Fish Trap Hole lies below a big rock on the left. It is said to be one of the deepest spots on the whole river, and in winter, when the water turns crystal clear, its sandy could be seen nearly twenty feet down. At it is about 8 feet deep today, among the deepest on the river. An Eminence resident who has done park work knew Fish Trap Hole and Fish Trap Hollow by those names in 2026, and Boyd Branch and Rail Tree Hollow as well.

Boyd Branch and Joe Boyd Ford

Creek and ford · right bank · about miles 28.6 to 29.4 · Plate A9

Below Fish Trap Hole the river runs east, shallow and choppy, over a smooth bottom of solid rock. A boy is said to have drowned in the above the mouth of Boyd Branch in the 1800s and to be buried at the edge of the field. Boyd Branch comes in on the right at mile 29.0 and drains about a square mile and a half. By one account it held water knee deep for a quarter of a mile or so, and it runs water farther than that. It is named, by the same account, for the Boyds who owned the mill at Alley (Reach H).

Thornton “Fodder” Jones and Bill Dyer, the story goes, were riding home from a pie supper when their horse stopped near the Boyd house, below the mouth of the , at a white, ghostly figure in the road ahead. Imaginations ran wild for a time, and when they looked into it later the ghost turned out to be a big gander hung in the fence. Joe Boyd Ford crossed the river between Boyd Branch and Big Bend Hole.

Big Bend Hole and Rail Tree Hollow

Pool and hollow · right bank (hollow) · about miles 29.4 to 29.8 · Plate A9

Just above Rail Tree Hollow the river makes a big bend from east to north under a bluff on the right that rises about 240 feet, and the pool in the bend is Big Bend Hole, about 8 feet deep at low water. Rail Tree Hollow comes in from the southeast on the right at about mile 29.7. It is a short hollow draining about half a square mile, and how it got its name has not been recorded. A second short hollow of the same size comes in on the left a little below, at about 29.8.
