Methods:	A Hydrolab SVR3-DL Surveyor 3 data logger and Hydrolab H20-BT Std. multiprobe were used to measure: depth, temperature, pH, specific conductivity, and dissolved oxygen (mg/l) at one meter intervals. The alkalinity was measured by performing Gran titrations using DL12K Mettler Autotitrator, Surface and underwater light transmission was measured using a Licor digital light meter. Secchi depth was measured using 22 cm disk. Notes: The hydrolab was calibrated for O2 weekly. Conductivity, and pH were calibrated monthly with commercial standards. Sampling Description. None
