Role of lake regulation on glacier-fed rivers in enhancing salmon productivity: the Cook Inlet watershed, south-central Alaska, USA

Surface-water hydrodynamics and regimes of a small mountain stream–lake ecosystem

“…This may be partially related to buffering of flood from rainstorms that was observed in this study, but most likely is a function of reduced sediment delivery below lakes for construction of floodplains that are sized to bankfull flows. Similar variation in flow regimes has been observed in larger stream-lake ecosystems on the Kenai River in Alaska (Dorava and Milner, 2000), though these flow regimes were not directly placed in the context of channel capacity. These findings, coupled with our results, suggest notable differences in streamflow regimes above and below lakes that occur due to variation in channel and floodplain size rather than major seasonal lake-modifications to streamflow quantity and timing.…”

Modulation of linear and nonlinear hydroclimatic dynamics by mountain glaciers in Canada and Norway: Results from information-theoretic polynomial selection

“…Alpine glaciers and ice fields lie at the hydrologic heart of many of these mountain ranges, impressing a distinct signature upon water quantity, water quality and freshwater and coastal marine ecosystems (e.g. Ward 1994;Dorava and Milner 2000;Fleming 2005;Mark et al 2005;Hood and Berner 2009;Neal et al 2010;Jacobsen et al 2012). Due to orographic precipitation and glacial melt, mountain headwaters often make inordinately large contributions to the flow of large rivers, and typically impart hydrological and biogeochemical signals that are clearly observable far downstream (e.g.…”

Identifying essential summer habitat of the endangered beluga whale Delphinapterus leucas in Cook Inlet, Alaska

“…Physical factors such as basin size, flow rate, tide, current, salinity, and water temperature which directly influence fish may indirectly impact prey of beluga whales (Moore et al 2000). Water flow is an important characteristic of fish habitat (Dorava & Milner 2000). Salmon require stream flows of adequate depth and velocities to successfully travel upstream.…”
