West Upper Lake
West Upper Lake is located near the city of Minnetrista. Head east on Minnetonka Blvd, and turn right on Co Rd 101 S. Turn right MN-7 and turn right at Hwy 44. Next turn right at Lake Minnetonka Regional Park and follow the path towards the public boat access. West Upper Lake is on Lake Minnetonka which is a class 2B lake protected for aquatic life and recreation. Water quality information is available starting in 1977, but regular monitoring did not begin until 1997. MCWD staff have been monitoring the site on West Upper Lake on a bi-weekly basis from the time of ice out (April) to the time of fall mixing (mid-October) since 2006. See Previous Reports. Monitoring season started in late April and ended in late October. A YSI multi-probe sonde was used to measure dissolved oxygen (DO), temperature (oC), pH, and specific conductivity (µS/cm) at each meter depth from the water surface to the bottom. Additionally, water samples were collected within the first two meters of the surface with a 2-meter composite sampling tube. Samples one meter below the thermocline and one meter above the bottom were collected with a Van Doran water sampler. Surface samples were analyzed for total phosphorus (TP), soluble reactive phosphorus (SRP), total nitrogen (TN), where bottom and thermocline samples were analyzed for TP and SRP. Surface concentrations of chlorophyll-a were also analyzed and measurements of Secchi disc depth were recorded.
