“…The downstream ecological and social impacts are subject to ongoing investigations [Rosenberg et al, 1995[Rosenberg et al, , 1997; World Commission on Dams, 2000]. Important biological implications range from interference with fish migration and biodiversity [Hart and Poff, 2002], to changes in downstream vegetation [Nilsson et al, 1997], and damaging river ecosystems [Ward and Stanford, 1995;.…”

[1] Retention in upstream storage dams results in modified riverine water and particle discharge patterns. Particularly, suspended solids input and intrusion dynamics in downstream lakes are affected by dam operations. In a case study, size-dependent particle budgets for peri-alpine Lake Brienz (Switzerland), downstream of major hydropower installations, were determined for a recent 8-year period (1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)) and compared to hypothetical no-dam scenarios based on numerical simulations. For this purpose, current tributary particle loads, as well as lake-internal sedimentation and turbidity dynamics, were assessed with in situ measurements. The analysis shows that hydropower damming drastically diminishes particle fluxes and minimizes (short-term) peak discharges. Reductions of high-flow events substantially cut the number of deep intrusions increasing particle supply to the lake surface layer. Furthermore, these hydropower operations shift particle inputs from summer to winter. As a consequence, such peri-alpine lakes become more turbid during winter and less turbid during summer, influencing the seasonal light regime and subsequently the dynamics of phytoplankton growth.

This paper deals with the analysis of phytoplankton composition and abundance from four sampling stations at the polymictic system, Rincón del Bonete water reservoir in Uruguay. Sampling data were obtained in 4 seasonal periods between February and November 1993. A hundred and twenty-four taxa were identified, where Aulacoseira granulata (Ehrenb.) Simon., A. granulata var. angustissima (Muller) Simon., A. granulata var. angustissima f. spiralis, (Muller) Simon., A. cf. ambigua, (Grun.) Simon., A. cf.. distans (Ehrenb.) Simon., Cryptomonas spp. and Synedra ulna (Nitzsch) Ehrenberg, were always present. Phytoplankton abundance fluctuated between 29 (autumn) and 2129 (summer) ind/ml. The general dominance of Aulacoseira spp. could be related to the polymictic condition of the system. In cold months phytoplankton distribution was homogeneous among sampling stations, while in warm months, spatial heterogeneity was detected, suggesting that sampling stations can behave as independent compartments.Key words: microalgae, freshwater, artificial lakes, Aulacoseira, Uruguay.

“…Indeed, hydroelectric development in Ontario has often been identified as an effective means of supporting growth of the economy in a sustainable way, establishing a long-term revenue stream through the sale of surplus electricity to surrounding markets (CHA, 2008;Krupa, 2012a). Nevertheless, hydroelectric development also has well-established impacts including: habitat and landscape destruction, environmental mercury contamination that detrimentally impacts food systems, and increased greenhouse gas emissions (Rosenberg, Bodaly, & Usher, 1995;Rosenberg et al, 1997). This is why the decision-making process related to the establishment of these projects is often described as inadequate (Paterson & Sears, 1993).…”

There is existing tension within many Aboriginal communities between economic development and preservation of traditional lands for the continued practice of traditional activities. The "duty to consult" doctrine has has become an important mechanism by which these concerns were identified and addressed (when possible) prior to development. This is a legal requirement that is rooted in the Constitution Act (1982) and subsequent legal case law that has further defined and outlined requirements under this obligation. This article describes the process that was carried out to advance the proposed Kabinakagami River Hydro Project Class Environmental Assessment in Northern Ontario, Canada with an emphasis on the approach to Aboriginal consultation. This project is unique because the co-proponent of the project is an Aboriginal community, with several neighbouring Aboriginal communities potentially affected by the project. This project raises questions about the approach to carrying out the duty to consult in an effective way. An evaluative framework was developed to examine timeline, information, means, and flexibility and transparency of the process to highlight shortcomings in the process and make recommendations for improvement.
