Ice Lake (also known as Crystal) is a small, 16.6 hectare (41 acre)
lake situated in the city of Grand Rapids, MN. The lake has a simple
bowl-like morphometry with a maximum depth of about 16 m (~53 ft).
The shoreline is almost entirely developed with houses on the north
shore and city streets running along the south and west shore. The
inlet to Ice Lake from McKinney Lake and the outlet to Hale Lake are
on the far west end of the lake. The lake receives urban stormwater
runoff from five storm sewers that discharge directly into its waters.
All of the homes surrounding the lake are sewered. See the lake
summary table for additional watershed and water quality information.

an overview of Ice Lake from 1998-1999.
water quality of the lake is of importance to the community
for recreational use and residential development.
Lake was selected by the Water on the Web project because faculty
at Grand Rapids High School (GRHS), Natural Resources Research
Institute at the University of Minnesota Duluth (NRRI), and
the Itasca Soil and Water Conservation District (ISWCD) have
been involved in the assessment and management of this site
for a number of years. In 1995, students of Ron Salladay at
GRHS performed a water quality study of Ice, Hale, McKinney,
and Forest Lakes and in 1996 these lakes were sampled as part
of the ISWCD lake assessment program.
the WOW project was originally conceived in 1996, Hale Lake
was selected as a study site because it was the least productive
of the Grand Rapids urban lakes and was similar to the more
productive Lake Independence in depth and thermal stratification
characteristics. Subsequent concerns from lakeshore owners
regarding the placement of the RUSS unit in an area with snowmobile
and water skiing traffic led to the switch to Ice Lake which
discharges to Hale. The WOW website still contains data from
Hale Lake which may be useful to specific lesson plans.
the spring of 1998 a two year project aimed at determining
the impact storm water discharge has on McKinney, Ice, Hale
and Forest Lakes was begun by ISWCD, the Minnesota DNR, citizen
volunteers, and NRRI. Nutrient budgets, suspended solids and
fecal coliform bacteria loading for Ice and Forest are being
determined as they are the most severely impacted by urban
runoff in the city. Mckinney and Hale Lakes are also being
monitored because they are situated in the watershed above
and below Ice Lake. The data from RUSS is an integral part
of this project. See
