Monitoring data collected between June 1996 and December 1999 were used to characterize water quality within Lake Waco with particular emphasis on factors influencing algal growth. A spatial analysis of surface water quality for Lake Waco established two different longitudinal patterns within the reservoir based on distance from major tributary inflows. For physical characteristics, such as con...

Dzialowski, A.R., S.H. Wang, N.C. Lim, J.H. Beury and D.G. Huggins. 2008. Effects of sediment resuspension on algal biomass and nutrient concentrations in reservoirs of the Central Plains. Lake Reserv. Manage. 24:313-320. Historically, lake and reservoir management has focused on controlling external nutrient loading. However, it is becoming increasingly clear that internal mechanisms, such as ...

Six reproductive classes of male Oligosarcus hepsetus (Cuvier, 1829), a medium-sized carnivorous Characiform species, are described based on macroscopic and histological techniques. A total of 175 individuals were caught monthly between April 2001 and June 2002 in the Lajes Reservoir, Brazil, one of the largest impoundment areas in the state of Rio de Janeiro. The reproductive classes were base...

Riverine dams alter both the physical environment and water chemistry, thus affecting species assemblages within these environments. In the United States, dam construction is on the decline and there is a growing trend for dam removal. The Choctawhatchee, Pea, and Yellow Rivers Watershed Management Authority had initiated the permitting process for placing a reservoir dam on the Little Choctawh...

Dynamics of a bloom-forming cyanobacteria (Microcystis aeruginosa ) in a eutrophic river /reservoir hybrid system were modelled using a genetic programming (GP) algorithm and multivariate linear regression (MLR). The lower Nakdong River has been influenced by cultural eutrophication since construction of an estuarine barrage in 1987. During 1994 /1998, the average concentrations of nutrients an...

this study investigated the effects of sewage discharge on nutrient concentrations and bod5 levels in the coastal waters and sediments ofthe city of mombasa. the results indicated that nutrient concentrations in tudor, mtwapa and makupa creeks were elevated as compared to concentrations in gazi creek (mean ranges of 0.022-0.039mg/l, 0.038-0.163mg/l and 0.034-0.118mg/lphosphates, nitrates and a...
