"Running water is a favorite haunt of faery kind. Indeed, crossing through or over running water is a method by which their realm may be reached. Be warned that the size of the body of water is of little concern to the fae. Oceans, lakes, rivers, springs and pools are as likely as teardrops and raindrops to harbor faeries.
Water faeries heal and purify the earth. Their presence is typically communicated to humans through dreams. "

http://thefae.freeservers.com/As a side note of Water Fae... be careful when working with water fae, many do not understand that humans cannot be underwater for extended periods of time... and some that do find it amusing to drown people... so use extreme caution when working with Water Fae (or any Fae for that matter).
