Forrest Road - Time Challenge - You can Block the water Influx!!!

On the map Forrest Road water is coming from the hill-side but there is some 'glitch' in the game that allows you to put just a little bit of dirt in front of it and no more water will flow down the hill. Of course it's a choice if you the time challenge to use the extra minute or minutes to stop that water or go directly clearing out the street. But it's an interesting concept.
