Judy Reservoir
The purpose of this study was to identify and count the phytoplankton and measure chlorophyll, total nitrogen, and total phosphorus levels in water samples collected from Judy Reservoir. Water quality and algal data have been collected on a weekly basis since October 2006; annual reports have been sent to the Skagit Public Utility District No. 1 in 2007, 2008, 2010 (January and December), 2011, and 2012. This project ended in 2013; the final chemistry sample was collected May 2, 2013 and the final algae sample was collected November 6, 2013.

Graduate Theses and Dissertations
Three reservoirs of similar size, watershed land use, and qualitative characteristics in northwest Arkansas, USA were selected to compare the effects of chemical fertilization and pulsed artificial-upwelling on whole-lake productivity, specifically primary production and phytoplankton biomass. Numerous water quality parameters were quantified over a two year period (2011-13) with the goal of understanding how each management technique would stimulate productivity. This experiment was the first step towards a larger goal to ultimately enhance sport fish production. The first year of monitoring occurred in 2011 and served as a control year for the three lakes. Treatments were initiated in two of …

Phytoplankton Life History Events: Resting Stages And Physiological Cell Death, Christine R. Kozik
Theses and Dissertations
Understanding and predicting changes in phytoplankton populations requires knowledge of key life history processes such as recruitment from benthic resting stages and losses due to sedimentation and cell death. Currently, these processes are poorly understood in freshwater systems. Phytoplankton resting stage and cell death life history events were separately examined in two freshwater systems in Wisconsin, four northern lakes and an urban pond. In the norther lakes, sedimentation and benthic recruitment were examined using sediment and recruitment traps that were sampled weekly over two summers. Sedimentation and benthic recruitment contributed little to changes in standing crop chl a, but rather …
