Action
Taken at
2001
Meeting
Last year we met on May 7, 2001 and the
Association discussed these subjects and took the following action:
·
Discussed problems with high water on the lake and the
possibility of a no-wake zone in the channel to Gilbert 3
·
Approved raising annual dues to $20
Improving
Fishing on Gilbert Lake

In May, 2001, Tim Brastrup from the DNR
released 250,000 walleye fry into Gilbert Lake. The stocking was part of a
multi-year test program in the state to see if walleye stocking can be
successful in non-traditional walleye lakes like Gilbert. Walleye fry are very
small, with 50,000 swimming in a five-gallon container. Survival rates are
typically under 1%.
Tim reports that the DNR plans to do
the same stocking again in 2003, and then make decisions about long-term
stocking plans.
The DNR conducted shock testing last
fall to see if any of the walleyes survived. Come to the meeting to learn the
results!
Gilbert
Lake Water Quality Declined in 2001

Water quality levels on Gilbert Lake
declined in the summer of 2001 compared to the previous two summers.
An
overall measurement of water quality is the TSI (Trophic State Index),
indicating where a lake is in its lifespan. The higher the index, the worse the
condition of the lake (algae blooms, etc.)
In
2001, the average TSI for Gilbert was 40, while it was 38 in 1999 and 37 in
2000. Phosphorus levels in Gilbert Lake were significantly higher in 2001 than
in previous years. We don’t know whether this increased eutrophication of
Gilbert is a normal fluctuation (e.g. caused by last year’s high water) or an
initial sign of more decline. In any event, we must all take efforts to protect
our lake from further decline.
Fortunately,
there are many simple steps we can do:
§
Minimize use
of any fertilizers. Absolutely do not
use any fertilizers containing phosphorus. One pound of phosphorus can
stimulate the growth of 500 pounds of algae! The amount of phosphorus is the
middle number on fertilizers, so look for fertilizers with zero in the middle
(for example, 10-0-10)
§
Maintain a
vegetation buffer strip along the shore. Do not plant grass to the edge
of the water, as lawn grasses do not stop the overflow of water into the lake
as well as native vegetation (the Lakescaping book and CD show examples of what
to do).
§
Minimize the
size of your beach. Though nice to play on, sand beaches easily erode. A thirty
foot beach is usually enough.
§
Minimize the
removal of aquatic vegetation. Aquatic vegetation, especially
emergent vegetation (lily pads, bullrushes), break the wave action that erodes
the shoreline.
§
Keep boat
traffic away from the shores. Large wakes erode the shoreline,
bringing phosphorus and sediment into the lake.
§
Regularly pump
your septic tank. Septic tanks quickly fill with fine
solids, plugging the drainfields. Not only will regular pumping help the lake,
it will also save you money. Replacing a failed drainfield is expensive. Septic
tanks may have to be pumped every year or two, and more often if you use a
garbage disposal.
§
Encourage your
neighbor to help keep Gilbert Lake clear!
"Lakescaping"
Having
a "buffer zone" at the edge of your shoreline is the solution to
reduce erosion, algae blooms and poor water quality, according to the authors
of the DNR book Lakescaping for Wildlife
and Water Quality. A buffer zone is a strip of natural vegetation along at least
75% of a property's frontage. The goal of creating the buffer is to restore the
shoreline with the native vegetation that was originally there, such as
wildflowers, shrubs, grasses, and aquatic plants. The benefits of a buffer
strip are many, as it:
·
Acts as a filter to
help prevent fertilizers and pesticides from reaching the lake
·
If planted with
native plants, doesn’t need any fertilizer
·
Helps reduce
shoreline erosion by slowing down and absorbing the water flowing toward the
lake
·
Keeps geese away from
your yard, because they don't like tall grasses and wildflowers
·
Reduces homeowner
maintenance because it doesn't need to be mowed
Without
a buffer strip, nutrients such as phosphorus can reach the lake and encourage
weed growth and algae blooms.
Best
of all, creating a buffer strip means less mowing and lawn work for you!
Copies of the Lakescaping book will be
available at the annual meeting at a reduced price for Association members ($12
–retail $20)

NEWSLETTER
PRODUCTION. We can use
someone who is willing to put together this newsletter. Right now, it won't be
anything more than an annual event. It
would be great if someone could help produce it more often.

CREATION OF A GILBERT LAKE ASSOCIATION
WEB PAGE. We can base a web page at Consolidated
Telephone's web site for free. Web
pages are quite easy to create with today's software, and it would be nice to
have a place on the web where all lake information could be posted or
accessed. We could also have links to
all the DNR data about Gilbert Lake -- lake maps, lake data, fisheries
information, etc.
