Primary Productivity of Southern Indian Lake before, during, and after Impoundment and Churchill River Diversion. Hecky, R., E. & Guildford, S., J. Canadian Journal of Fisheries and Aquatic Sciences, 41(4):591-604, 1984. Paper abstract bibtex The lake had regional differences in chlorophyll concentrations and daily rates of integral primary production in 1974 and 1975 prior to impoundment. Regions receiving Churchill River flow tended to have higher chlorophyll concentrations and production rates. Impoundment resulted in higher efficiencies of primary production in all regions. Many large basins of the lake had light penetration reduced by high concentrations of suspended sediment from eroding shorelines; other areas had relatively unchanged light penetration. The increased efficiency of carbon fixation per unit chlorophyll resulted in higher rates of integral production in those regions where light penetration was not greatly affected. Daily rates of integral primary production in lake regions where light penetration had decreased markedly were not significantly different after impoundment because efficiencies of light utilization were higher. Turbid regions are now light deficient on average. Phosphorus deficiency, has been eliminated as the mean water column light intensity declined below 5 mEinsteins.m-2.min-1. -from Authors
