Keep in mind that the people who make ice also do all of the Parks snow removal. When it snows, the crews are not making ice and instead need to remove the snow from all of the rinks. In order to put water down again on a rink, the snow must be completely gone. Leftover snow, once frozen, may lead to uneven ice. That won’t do. Note: Hockey rinks with boards require blowing or hand-shoveling the snow up and over the boards and out of the rink.
