Benthic Invertebrate Study of the Churchill River

4.3.5.4 Biotic Interactions

The composition of benthic communities depends in part on the presence of “keystone” predaceous benthosand fish. Fish that feed upon benthic invertebrates typically exert control on large benthic taxa (e.g.,Isopoda, Ephemeroptera, Plecoptera, Trichoptera). In contrast, large predaceous benthic taxa (e.g.,Plecoptera, Odonata) will control numbers of other smaller benthos. Predatory taxa often prevent themonopolization of resources by only a few taxa. Consequently, the presence of predatory taxa oftenincreases species richness. The reduction of predaceous taxa (either fish or benthos) can, therefore, resultin a reduction in overall benthic species richness (Ward and Stanford 1979).

4.4 Summary of Literature Review

Benthos of boreal forest, rock-bottomed streams/rivers are typically diverse with potentially hundreds ofspecies of benthic invertebrates. Benthos of sand-bottomed rivers, in contrast generally have fewer taxabecause sand is a relatively severe environment for benthos. Most of the benthos found in northern riversare also found in southern systems, although life-histories may be altered (shortened reproductive periods).The generally sandy nature of the Churchill River will limit the number of taxa, as well as total benthicabundance, biomass and production. Other parts of the river are armoured by large cobbles which are alsoa difficult substrate for benthos. Typically, it is the more tolerant benthic organisms that can withstand thestresses associated with sand or armoured substrate.

Upstream of the dams in headponds, several impacts may be predicted. First, the conversion of a lotic toa lentic habitat will alter the composition of the benthic community. Those forms requiring flowing waterwill be replaced by those forms requiring or tolerant of still waters. Benthos will colonize newly floodedsoils, but abundances of benthos will be unstable in the early years of the impoundments. Drawdown (ifpresent) will significantly reduce numbers of benthos in littoral areas, as will other sources of erosion inlittoral areas. Deep benthic habitats in the head pond may be affected by nutrient enriched soil particles,with two potential effects: anoxia and further reduction of the benthic community or, in the absence ofanoxia, the enriched sediments may actually fertilize the benthos leading to increased numbers. Theflooding of new soil may lead to the production of methyl mercury. This additional production of methylmercury could result in elevated tissue concentrations of mercury in benthic organisms and ultimately infish.

Within newly flooded or impounded areas, formerly running water habitats are converted into standing waterhabitat. In the present case, the headpond created behind the proposed structures at Gull Island and MuskratFalls would be deep, long and narrow, and largely confined within the steep valley walls. As a result, incontrast to the situation at the La Grande Complex in Quebec, or the Southern Indian Lake project inManitoba, the surface area of the newly impounded headpond would not be as large, in comparison with the
