Lake Water Quality Assessment
Physical Information
Name: Minnetonka -Upper Lake
DNR Lake ID nu mber: 27- 0133 -05
County: HENNEP
Location from nearest town: 1.5 MI SE OF MOUND
Ecoregion NCHF
Basin UM
Hydrologic Unit Code 0701020
Surface Area: 4196.618 (acres)
Maximum depth: 83 (feet)
Water Body Ty pe: P
Latitude /Longitude: 44.91083333/- 93.63583333

This summary is based on available summer (June through September) data in STORET ( STORET is
the national water quality data repository developed by the United States Environmental Protection
Agency. All water quality data collected by MPCA or received from external groups is placed in
STORET.) collected between 1997 and 2006.
Data Quality Excellent
Aquatic Recreation Use Support Fully Supporting Lakes are better than the aquatic recreation use support
thresholds with sufficient data to make an assessment. These lakes are considered to be assessed for
aquatic recreation and fully supporting by the MPCA.
