*Angular crushed stone, which will "knit" or lock together and be less likely to shift, is recommended. However, for aesthetic purpose smooth river run stone may be desired.

*Stone size is determined by flow velocities at inlets and outlets, but typically ranges between 50 mm and 250 mm. The larger the stone,

*Stone bed is twice as thick as the largest stone diameter.

*Stone beds should be twice as thick as the largest stone's diameter.

*To prevent erosion of soils beneath the stone and the migration of the stone into the soil, the stone bed should be underlain by a drainage geotextile.

*While crushed stone will be less likely to shift, river-run stone may be used to create a dry-stream-bed look.
