Michael Dirr in his book on Hardy Trees and Shrubs suggests Canadian Hemlock and in particular 'Sargentii'. It is a weeping variety that grows to approximately 10 to 15 feet high and 20 to 30 feet wide. You might want to check out that one but I have no idea how fast it would grow or if it would be suitable in your particular site. You might contact an arborist for better information. You might not think of it but my personal experience with a creek was that it flowed little in the Summer but in the Spring after snow melt it became a raging river! The placement of the new plants would be critical to their survival.
