      White sturgeon, Acipenser transmontanus, is the largest, longest-lived freshwater fish species in North America. The species’ most distinguishing features include a mainly cartilaginous skeleton, long scaleless body covered with rows of large bony plates (called scutes) on the back and sides, shark-like (heterocercal) tail, and four barbels between the mouth and an elongated snout.

/ R.J. Daley [et al.] Environment Canada Vancouver The Arrow Lakes Reservoir and Kootenay Lake are comparable large reservoirs formed by the addition of storage onto natural lakes. Both have significant storage reservoirs upstream that are capable of subsurface withdrawal, but both show elevated outflow temperatures.

For these reservoirs the presence of upstream dams capable of subsurface release of colder hypolimnetic water makes an observed Cited by: Large-scale seasonal addition of limiting nutrients has been used for restoration in Kootenay Lake, British Columbia, since to mitigate cultural oligotrophication resulting from upstream hydropower development, river channelization, mysid shrimp introduction, and extensive tributary floodplain : Eva U.

In lakes with high abundances of planktivorous fish, water clarity or light penetration is reduced because large zooplankton, which feed on small algae, are reduced by fish predation.

Some of the largest impacts to habitat, biological communities, and ecological function resulted from levee construction along the km of river upstream from Kootenay Lake, completed by the s, and the construction and operation of Libby Dam on the river near Libby Montana, completed in Author: Ryan Sylvester, Brian Stephens, Joel Tohtz.

Autochthonous production is often altered upstream of small impoundments, such as beaver dams, but few studies have examined how such impoundments affect downstream production.

A better understanding is needed of how production and organic matter dynamics are affected by natural : J.

[21] In order to evaluate the effects of altered light regime (due to upstream hydropower operations) and of reduced bio‐P input (oligotrophication) on the ecosystem of Lake Brienz and to test the sensitivity of the biogeochemical model to individual parameters, a set of eight hypothetical scenarios was developed with (1) variable bio‐P.

Daley et al. () calculated that % of the decrease in Kootenay Lake (British Columbia) biological productivity was due to the presence of some upstream impoundments, and they also predicted that levels of phytoplankton and zooplankton would be reduced to less than a half of what they would have been had the dams not been constructed.

Two reference sites on the upstream of reservoir, one site on the impoundment and one at the downstream were selected. The sites from S 1 to S 4 were used to study the degree of downstream habitat alteration and the impacts of impoundment on benthic macro invertebrates.

The sampling sites were designated as S 1 to S 4. Data Collection. As the effect of beaver impoundments might be transient and local, we compared DOM quality and biodegradability of both pond and upstream sections of differentially aged beaver systems.
