Short-Term Load-Response Relationships in Shallow, Polluted Lakes

Eutrophication of Freshwaters

“…An expression of the 'stirring capacity' of short-term winds (a few days) in shallow Swedish lakes showed good agreement with chlorophyll increases (Ryding and Fosberg, 1982). In extreme cases, such as shallow enriched prairie lakes in North America (Barica, 1974), this may result in a series of oscillations, with collapse of algal blooms through nutrient depletion followed by deoxygenation, nutrient regeneration, and renewed algal growth one to two weeks later.…”

Newman Lake restoration: A case study. Part I. Chemical and biological responses to phosphorus control

“…Direct measurements that would permit estimation of TP settling rates are also not available, and these rates often have high annual variability (Ryding andForsberg 1980 , Chapra 1997). The net internal load calculation is therefore the best available indication of prevailing TP movement relative to the sediments.…”

Hydrology and water quality of Whitewater and Rice lakes in southeastern Wisconsin, 1990-91

“…Motorboats in shallow hypereutrophic systems have been found to resuspend the bottom sediments, which results in an increase of phosphorus concentrations in the water column (Wright and Wagner, 1991). Winds can also cause resuspension of the lake sediments and phosphorus in shallow hypereutrophic systems (Ryding and Forsberg, 1980).…”
