Subject: Minutes
of Joint Meeting with Polk County, St. Croix Tribe, Blue Water
Science
and Lake District in Hertel November 29, 2006.
District Members: Gordon
Kill, Dan Bergeron, Sallie Tinkerman, Truman Roach
St Croix Tribal: Martin
Shutt, Elizabeth Grieff
Polk County: Amy
Kelsey, Jeremy Williamson
Meeting Summary:
Gordon Kill reviewed lake conditions and activities
performed this year.
- Lake
water levels were lower than normal due to low snow runoff and lowerthan
average rainfall during the summer.
- The
level of curly pondweed continued to recede esp. from 2003-2004 levels.
- The
Lake District contracted with Blue Water Science to perform Plant Surveys
and Water Quality tests on Big Round during 2006.
- Paul
Garrison (DNR) completed the deep sediment core sampling in early October. He was assisted by Jeremy Williamson and
Dan Bergeron.
- We did
not obtain the requested grant money for this project due to other priorities
from the State budget process. However we are working on some potential
partial funding for this project.
- The
Fishing Report for Big Round indicates the Walleye numbers were down this
year however the Bass and Panfish fishing was very good esp. in spring.
- We are
requesting a reduction in Bass size restrictions to allow more Bass to be taken
and therefore have some impact on the Bass Predation problem on the fingerlings
stocked.
Steve McComas reported on the Plant Survey completed June 6
and August 28, 2006.
·
These Plant surveys indicate distribution and density of
all submerged aquatic plants present in the lake.
·
Of significance is the continued reduction in the
incidence of Curly Pondweed. The studies indicated approximately 315 acres
present in 2003, 260 acres present in 2005 and 160 acres in 2006.
·
Jeremy Willimson indicated the studies provided very
good info but would need to increase the number of lake intercept points
(sampling stations) to qualify for DNR lake management programs. It would also
be helpful in the event of sudden presence of invasive species such as Eurasian
Milfoil. This issue will have to be discussed with the DNR.
·
Water quality study trends indicate higher algae
content in August and early September timeframe. Secchi Disk readings illustrate
an average water clarity in June of approximately 10 ft whereas in August
approx.2-3 ft are shown.
Beth Grieff presented the Tribal Fish report.
- Spring
surveys have indicated approximately 3 walleyes per acre. However, she
emphasized that these counts are just a snapshot. For instance in 1989 3.7
per acre, 1991 1.98 per acre, 1997 3.7 per acre. More extensive fish
counts planned by the Tribe in 2007.
- Walleye
reef built in 2003-2004 indicated some spawning activity in 2004 however, none
found in 2006.
- Average
fingerling size stocked from 1988-2006 is 2.4in.
- The
Tribal Group stocked 2001-102,351, 2003-52,473, 2005-51,567 2006-9,951
fingerlings in Big Round. Normally every other year.
- We can
increase stocking numbers, however Big Round lake conditions are not
conducive to walleye survival.
- Extended
growth walleye stocking (7-9 in.) normally improves survival rate in some
lakes but may not be effective in Big Round.
Projects planned for 2007.
- Tribal
group needs to decide on continuing grant request for treating Curly
Pondweed. In lieu of
declining presence of that species the last 2 years it may not be a
viable use of the grant funds.
- The
Lake District plans on 2 plant surveys in early summer and late summer of
2007.
- A
water quality study is planned and continued water sampling and Secchi
Disk readings will take place.
- The
tribal Group offered some potential funding aid for the Plant Survey.
Dan Bergeron reported his findings regarding the outlet dam
on Big Round Lake.
- Some
form of the dam was built in the early 1900’s.
- Before
the dam the lake level was
substantially lower, (4-500 acres).
- The
current land on each side of the dam is owned by a Ms. Schilling, a long
time lake resident.
- She is
vehement about any modification to the dam which would affect her
property.
- There
is potential legal liability on the owner of the Dam from any flooding
which may occur downstream.
- If the dam were to become Lake District property
then control would be subject to DNR review, but still the responsibility
of the District. The District would be responsible to bring the dam up to
State requirements.
The meeting was adjourned.
