Verkhne Viiskii Reservoir (surface area = 6.0 km2; volume = 36.0 hm3), one of two water supply reservoirs for the City of Nizhnii Tagil, is located in a forested watershed (drainage area = 272 km2) in the Ural Mountain region of the Russian Federation. This study, conducted in August 1999, provides a benchmark limnological assessment against which to gauge future change. While currently meeting local water quality requirements for drinking water sources, the reservoir exhibits moderately eutrophic characteristics, including elevated epilimnetic nutrient (total P = 0.048–0.115 mg L−1; total N = 0.421–0.508 mg L−1) and chlorophyll (4–8.4 μg L−1) concentrations, and a high rate of hypolimnetic oxygen depletion (4.07 g m−3 mo−1).
