The California Lake Management Society is hosting this free webinar on managed nitrate addition to enhance water quality in lakes and reservoirs.

Nitrate is a significant water pollutant with potential environmental impacts ranging from eutrophication to health risks to infants. But under certain circumstances, nitrate may enhance water quality through a number of mechanisms, including regulation of redox potential and suppression of nitrogen-fixing cyanobacteria. In this webinar, Dr. Beutel will explore a range of case studies in which nitrate addition enhanced surface water quality including purposeful addition of nitrate to lakes to repress internal phosphorus loading, enhance organic matter oxidation, and impede bottom-water accumulation of methyl mercury; incidental addition of nitrate from point and non-point discharges to reservoirs and lakes; and nitrate addition to lakes to affect phytoplankton and zooplankton composition.
