toveling kailim in snow

Hi, I remember learning that it was ok to tovel stuff in snow. is there a requirement for the depth of snow? and does it count if I use a shovel to pile up the snow? thanks!

Snow can be used to complete the minimum size of a mikveh. Even if it’s shoveled. It can also be used as a kosher mikveh if it melts and is the proper size of a kosher mikveh.
Toveling something in the snow is a machloket and we don’t do it.
