What is the Name of that Book? - Girl Sliding Down Staircase

[Em]

I have been looking for a book that I saw on the Reading Rainbow show when I was a kid.

It is a children's book about a young girl who was sliding down the stairs in her home and let her imagination run away with her. As she was on her but going down the stairs, water started slowly flowing past her. The amount of water increased until it was much like a waterfall. She saw the whole first floor was liken to that of a pond with lily pads and maybe a blue heron. The book had beautiful illustrations, but that is all I can definitely remember.

Any other slightly memorable, but not definite information was that she was a Caucasian girl maybe with lighter colored hair and possibly wearing coveralls.

My folks usually taped them and I've gone through all of the video cassettes we have at home as well as online at the Reading Rainbow site and have tried to find Youtube episodes with no luck. I don't remember if LeVar Burton read it or if a kid did or if an actor read it during the show. If you have any ideas, I would greatly appreciate them!
