re: I filled spots with "pumped river sand" ...

Filling is best done with the sandy alluvial soil deposited in our area by the Mississippi River. Soil that is deposited in the river bed and dredged or pumped out to keep the river open to large ships is called pumped sand or sugar sand.

Soil obtained from the area between the river and the levee is called batture sand.
Pumped and batture sand are also called river sand. Alluvial soil obtained from the Bonnie Carrie spillway is called spillway sand.

It's generally best not to use spillway sand because it's more likely to contain seeds, bulbs or bits of rhizomes of weeds, such as nutsedge, dollarweed and torpedograss. Pumped sand and river sand typically do not have this problem.
