Bank Run Gravel vs River Rock: Size, Cost, and Which to Use

Bank Run Gravel runs about $7 per ton and River Rock about $61 per ton. Compare size, drainage, compaction, and which one to use.

Overview

Bank Run Gravel

Bank run gravel is pit-run aggregate dug straight from a gravel bank, pit, or river terrace and sold with almost no processing. It costs $7 to $16 per ton in 2026, weighs 1.4 to 1.65 tons per cubic yard, and is the cheapest truckload of anything most yards will sell you. What you get is whatever the deposit holds: sand, small gravel, stones up to several inches, and enough silt or clay fines to fill the gaps.

River Rock

River rock is naturally rounded stone from river beds and glacial gravel deposits, washed and screened into size bands from 3/4 inch to 8 inches. It costs $61 to $142 per ton in 2026, weighs 1.35 to 1.6 tons per cubic yard, and is the go-to decorative stone for dry creek beds, garden beds, borders, and drainage swales where the rock needs to look good and stay put. It costs two to three times what crushed stone costs because it is sorted and washed, and because the supply is limited to places with river gravel.

Sizes & Colors

Bank Run Gravel

An unscreened blend running from sand and fines up through stones of 4 to 6 inches, with most of the material between 1/4 inch and 3 inches. There is no standard mix. The deposit sets the blend, so the pile at one pit looks nothing like the pile at the next one, and color follows the local geology from gray to brown to reddish tan.

River Rock

River rock is sold by size band: 3/4 to 1 inch (sometimes called large pea gravel), 1 to 2 inch (egg rock), 2 to 3 inch, 3 to 5 inch, and 5 to 8 inch cobbles. Every piece is smooth and rounded. Colors are a natural mix of tan, brown, gray, cream, rust, and black, with regional loads that run mostly one shade. Single-color sorted rock costs more.
