Judy Reservoir Monitoring Project 2013 Final Report, Robin A. Matthews, Joan Vandersypen
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.

Reed Lake 2013 Aquatic Plant Survey, Samantha Merrick, Robin A. Matthews, Joan Vandersypen
Reed Lake
The main objective of this project was to collect and identify aquatic plants in Reed Lake, a small, shallow lake in Whatcom County. The project was undertaken with the assistance of volunteers from the Glenhaven Lakes community (Figure 1). Residents of the Glenhaven community have expressed concerns about the effects that aquatic plants are having on recreation in the lake. This report included maps showing the types of plants that were collected in the lake Figures 2–10 and estimated plant densities (Figures 11–13), with a short discussion of methods that might be useful for reducing aquatic plant densities in the …
Understanding Basin Specific Life History Characteristics Of Lake Mead Quagga Mussels (Dreissena Bugensis) And A Potential Treatment Using Uv Radiation In Laboratory Studies, Melissa Thaw
UNLV Theses, Dissertations, Professional Papers, and Capstones
The quagga mussel (Dreissena bugensis) is an aquatic invasive species that is spreading throughout Lake Mead and other western waterways. Unlike their native waters in Eurasia, Lake Mead exhibits year round warm temperatures, high calcium levels and a lack of natural predators, all of which are very favorable conditions for their growth and spread. Dreissena bugensis reproduce and colonize hard surfaces rapidly, where they filter large amounts of water. They disrupt the aquatic food chain and interfere with infrastructure that is exposed to lake water. There is an urgent need to understand Dreissena bugensis life history characteristics within this new …
