“…Recreational flows are water releases made to accommodate activities such as rafting and kayaking. It is well recognized that sudden flow fluctuations may cause stranding of juvenile salmonids in shallow side channels (Maciolek and Needham 1952;Hvidsten 1985) and on river bars (Bradford et al 1995), and it is now common for dam operators to address this problem by gradually ramping flows up and down during pulses (e.g., PGE 2005a), thus allowing pulsed flow regimes to continue. Although pulsed water releases provide obvious benefits to humans, the cumulative effects of repeated and unseasonal flow pulses on aquatic communities are relatively unknown.…”

We tracked the movements of ten small (SL=25.5-31.0 cm) and ten large (SL=32.0-38.5 cm) radio-tagged domestic rainbow trout (Oncorhynchus mykiss) in response to frequent pulsed releases of water in the South Fork American River (California) from July to October 2005. In week one all the small trout moved less than 1 km upstream or downstream of their release sites. Four small trout moved 1-3 km upstream or downstream of their release sites in the following 8 weeks. Seven out of ten large trout moved downstream after their release. In subsequent weeks most large trout showed smaller upstream and downstream movements, and were observed between 1 km upstream and 8 km downstream of their release sites. Our results suggest that domestic rainbow trout with SL>25 cm are not forced downstream by daily pulsed flow increases from 5 to over 40 m 3 s −1 .

“…A fast water level decrease may lead to increased stranding risk for organisms because they may not be able to perform a lateral shift fast enough with a rapidly sinking water level. Several studies observed a positive relationship between stranding and down-ramping rate (Bauersfeld 1978;Hunter 1992;Bradford et al 1995). For brown trout Halleraker et al (2003) found a significantly decreased stranding rate, when down-ramping rate was reduced from 60 to 10 cm/h.…”

“…Furthermore, Berland et al (2004) observed higher stranding of Atlantic salmon parr, and Bradford (1997) found higher side-channel trapping, both during night and summer conditions. During winter conditions other studies showed increased stranding risk for some salmonid species during the daytime (Bradford et al 1995; Saltveit et al 2001; Halleraker et al 2003). Summarizing, behavior seems to be influenced by the photophase as well by seasonally related factors such as water temperature.…”

Since elements of nature and society interact to determine the integrity and trajectory of these systems, they are referred to hereafter as socialecological systems (SESs). This introduction opens the door to these topics in four steps. It begins by explaining why a book dedicated to river management and science is needed at this point. In the second part, it outlines the history of some of the major developments that challenge the integrity of SESs worldwide. In the third part, it describes several of the principal tools used to study as well as manage SES. Tools to measure the degree of degradation of an SES include indicators of biological integrity, ecosystem health, and resilience. Tools to assess and manage the trajectory of an SES include the DPSIR and adaptive management. The introduction closes by outlining the structure of the book through the progression of its chapters.

“…Hydrological indices are used for classifying rivers (Poff and Allan 1995;McMahon et al 2007;McLaughlin et al 2014), measuring flow alteration (Richter et al 1996;Nislow et al 2002;Mathews and Richter 2007;Macnaughton et al 2015), and assessing the influence of flow regime on ecological processes and community attributes (Poff and Allan 1995;Kennard et al 2010). For instance, short-term variation of flow can cause fish stranding mortality (Cushman 1985;Bradford et al 1995;Young et al 2011) and downstream displacement (Jeffries et al 2005). High flow events such as spring floods constitute biological cues to trigger spawning (Nesler et al 1988), hatching (Naesje et al 1995), and migration (Irvine 1986).…”

“…However, the relative contributions of flow regime and habitat properties on fish community attributes, to our knowledge, have not been assessed in river segments downstream of dams across multiple regulation types. In addition, most studies that examined the effect of flow regime or habitat properties on fish community attributes focussed on relatively few species or rivers (Bradford et al 1995;Almodovar and Nicola 1999;Flodmark et al 2004). This impedes identification of generalized trends linking flow regime, habitat properties, and fish community attributes.…”

Effects of river scale flow regimes and local scale habitat properties on fish community attributes

et al. 2016

Community attributes result from processes operating at various spatial scales. The hierarchic organisation of rivers and the prevailing hypotheses about the variables that affect fish communities make lotic ecosystems particularly suitable to study processes taking place across spatial scales. The general goal of this study was to investigate how river flow regime and local habitat properties explain and predict fish community attributes in unregulated and regulated rivers. Our objectives were: (1) to identify the hydrological indices that best describe the flow regimes of river segments subjected to different regulation types (unregulated, run-of-the-river, storage, and peaking), and; (2) to estimate the relative importance of hydrological indices (river scale), and water depth, water velocity, and substrate composition (local scale) in explaining and predicting local fish community attributes (species richness, total density, and total biomass). We surveyed 880 sites (*300 m 2 ) in 25 rivers (14 unregulated and 11 regulated) located in six physiographic regions of Canada. Based on a discriminant function analysis, nine hydrological indices were selected to represent river flow regime. Models of fish community attributes were developed using linear mixed-models (LMM) by nesting sites within rivers and regions. A few hydrological indices along with habitat properties predicted fish community attributes at the site scale (0.43\ cross-validation R 2 CV \0:66). Specific hydrological indices and local habitat properties can be managed to preserve fish community attributes in regulated rivers. Combining variables associated with different scales in a LMM was a powerful and efficient way to model fish community attributes and produced reliable predictive models.
