| Rehabilitation of a Severed Meander Bendway: Effects of Flow Augmentation - Project Information |

| Project Information
Seasonal flooding of riverine backwaters is important for maintaining diverse aquatic habitats (Dodds 2002). Anthropogenic impacts have reduced frequency and duration of such flooding at many sites (Gore and Shields 1995). This causes riverine meander bendways and backwaters to be severed from their original river flood plain.As a result, environmental quality declines due to habitat degradation, destruction and non-point source pollution associated with agriculture. Various approaches have been suggested to address habitat degradation and loss within agricultural landscapes (Brookes and Shields 1996; Buijse et al. 2002). One approach is rehabilitation of aquatic habitats through hydrologic manipulations via flow augmentation. Such rehabilitation may result in aesthetic, recreational, ecological and water quality benefits (Cooper and Knight 1991; Shields et al. 2002). The purpose of this study is to compare water quality during a late summer 30-day flow augmentation period to 28-day pre-treatment and 26-day post-treatment periods.
