The retention or release of nutrients into the water column from sediment, also known as internal loading, is another source of nutrients to the lake water column. Sediment cores collected from Willow Creek Lake in September 2013 and June 2014 were incubated for 7 days to assess potential for sediment to produce or consume water column phosphorus under aerobic (oxic) and anaerobic (anoxic) conditions using techniques similar to Penn and others (2000); the oxic conditions served as a control and the anoxic conditions represented typical lake sediment environments. Phosphate as phosphorus and total dissolved phosphorus release rates (milligrams phosphorus per square meter per day) were estimated by dividing the change...
