Stream diversion projects in the Alberta Oil Sands Environmental Research Program study area that have been or will be required in the course of oil sands development are outlined. The effects of stream diversions on aquatic life, natural recovery of stream ecosystems from the effects of diversion, effectiveness of habitat restoration or enhancement techniques, and potential applications of biomonitoring techniques for studying the effects of diversions are reviewed with special reference to the AOSERP study area. Scientific references pertaining to these topics are compiled in an annotated bibliography. Information \"gaps\" and research needs pertinent to the AOSERP study area are briefly outlined. The primary research need recommended at the present time is to collect as much information as possible about the effects of the Beaver Creek diversion to aid in planning future diversion projects and related programs of environmental research in the AOSERP study area.
