History
Since the early 1950's there have been various efforts
to improve the lake  conditions.  The Black Otter Lake
District was formed in 1976 to help restore and
protect the lake.  In 1982, 1992 and again in 2002,
lake studies that resulted in management plans were
completed.  Both the Village of Hortonville and Black
Otter Lake District (BOLD) have followed up on many
of the recommendations proposed from past
management plans.  In 1989, the lake was drained
and approximately 120,000 cubic yards of sediment
were removed from a 55 acre portion of the lake.  In
January 2003 the most recent lake management
study was completed.  This study found high levels of
nutrients continued to enter the lake.  A small-scale
aeration system was installed in the lake in order to
maintain a viable fishery.
