“…Of the four case studies found in the published literature, three of these confirmed that invasive fish spread upstream of the former dam site (Gottgens, ; Kornis et al ., ; Marion, ), but the fourth did not observe an upstream invasion (Stanley et al ., ). Marion () found nonnative Alabama spotted bass ( Micropterus henshalli ), which can hybridize and compete with native redeye bass ( M. coosae ), upstream of the removed Woodside dams on Twelvemile Creek in South Carolina.…”

“…However, the magnitude of impact, if any, of the spotted bass invasion was not known. In the case of the removal of Big Spring Dam from Big Spring Creek in Wisconsin, nonnative white sucker ( Catostomus commersonii ) and Yellow Perch ( Perca flavescens ) quickly invaded upstream and became a major portion of the fish population, while the native Mottled Sculpin ( Cottus bairdii ) population decreased by more than half (Kornis et al ., ). In the Ottawa River in Ohio, the removal of Secor Dam coincided with the spread of invasive round goby ( Neogobius melanostomus ), a potentially harmful and difficult‐to‐contain invasive fish (Corkum et al ., ).…”

“…To combat some of these effects, river managers, scientists, and non-governmental organizations have argued for management plans to ameliorate the effects of impoundment on watershed connectivity. In some instances, dam removal has been the preferred option as it provides the more robust opportunity for re-establishing sediment and hydrologic connectivity (Grant and Lewis, 2015;Foley et al, 2017;Major et al, 2017) while also having immediate impacts ecologically by permitting fish passage (Kornis et al, 2014;Pess et al, 2014;Magilligan et al, 2016a) or by providing the necessary sedimentological conditions for enhancing spawning habitat (Magilligan et al, 2016b). In instances where removal is not an option, watershed managers have advocated for environmental flows (Bunn and Arthington, 2002;Arthington et al, 2006) to best mimic the natural flow regime (Poff et al, 1997) with the goal of re-establishing greater hydrologic connectivity especially across the riparian zone to maintain floodplain forest communities (Rood et al, 2005) or to generate longitudinal and lateral sediment connectivity and bar formation (Schmidt et al, 2001;Topping et al, 2005).…”

“…This has led to some debate about leaving barriers in place or even adding them to the landscape to protect native fishes [76,113]. In one case, the removal of a dam in Wisconsin, USA, resulted in increased competition and more intense predation from previously absent species in stream fish communities [77]. Given their importance to fish distribution, barriers and network structure should be explicitly included in models of fish community structure to determine the best conservation value for taxonomic, functional, and phylogenetic aspects of diversity [114].…”
