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

Dynamics ofAphanizomenonandMicrocystis(cyanobacteria) during experimental manipulation of an urban impoundment

“…They predict an increase in N may drive a species shift from Aphanizomenon to Microcystis, and we observed that in 2006 . Multiple other studies in the United States have illustrated that controlling P levels alone is an economical and efficient way of reducing overall cyanobacterial BV (Moore andChristensen 2009, Welch 2009). …”

Changes in Phytoplankton Structure due to Prematurely Limited Restoration Treatments

“…The reduction of nutrient loads causes changes in community structure at each trophic level [44]. An increase in the abundance of such phytoplankton groups as Chlorophyceae, Cryptophyceae, and Chrysophyceae was observed during the sustainable restoration, as in other restored lakes [12][13][45][46]. Chrysophytes and cryptophytes are noted as prevalent in P-deficient sites [47][48].…”

Newman Lake restoration: A case study. Part II. Microfloc alum injection

“…This is especially true late in the summer, when thermocline depths are close to the maximum depths of the northern and southern lobes of the lake (see Fig. 1 in Moore and Christensen 2009), so that upwelling may impact a relatively large portion of the lake surface area. Vertical entrainment is demonstrated by the consistent pattern of thermocline deepening, observed for every year in which measurements have been made in Newman Lake.…”

“…( Moore and Christensen 2009). Although available data are not adequate to totally isolate contributions of each practice to algae and nutrient reduction, it is possible to infer aspects of microfloc alum injection efficacy based on observations of lake processes.…”
