Abstract/Artist Statement
One of the main sources of water pollution into the San Francisco Bay Area includes runoff from urban areas. Many creeks flow into surrounding reservoirs either used for drinking water, irrigation, and recreational uses. This study investigates how urbanization affects Lake Don Castro in Hayward, California and the surrounding Oakland watershed. The lake that is of interest between the three is Lake Don Castro. The data used are f rom samples that were retrieved approximately weekly since January 2013. There are seven main categories that we will be observing including depth, temperature, conductivity, total dissolved solids, salinity, dissolved oxygen, and pH. All samples were collected at either the inlet, middle or outlet of the lake from depths varying from .5 to 2.5 m at the inlet and outlet. Currently, the findings collected from Lake Don Castro indicate that in the testing areas the lake tends to stratify during warmer temperatures, meaning the water varies by temperature with the warmest water on top of the lake, which can lead to an excess of nutrients and decrease of dissolved oxygen. During the Pacific Undergraduate Research and Creativity Conference, I will be using a poster to discuss methods, current findings and preliminary conclusions reached from our findings.
