or 6 different steps accomodate different river levels.

like a floating dock always dry, but cheaper and easier to maintain.

there's a local park which has blocks of limestone for a terraced

limestone in the area and a cheap supply from construction sites.

we also have those wire chain link cages full of broken rock along
riverbanks to stop erosion. they make good launch sites.
