The
Rice Creek Watershed District Board of Managers held the public hearing
on the Bald Eagle Lake alum treatment on October 9. No members of the
public made comment at the meeting.
Manager John Weller asked
about the accuracy of the report that 14% of the phosphorus load in the
lake comes from Judicial Ditch #1. He pointed out that several years
ago work was done to reduce that number by installing collection ponds
on the east side of Highway 61 near Buffalo Street. RCWD staff member
Matt Kocian agreed that the 14% number was based on data from prior to
the work on the ponds and that it is likely that the actual number is
now lower. He was not able to give a revised estimate of the percentage
of phosphorus that comes from JD#1.
Manager Weller also expressed concern that grass clippings
and leaf litter from homes within the watershed were a contributor of
phosphorus and yet little was said about dealing with that problem. Mr.
Weller said that few people seem to understand what can be done to
limit that material from entering the watershed. Staff member Jessica
Bromelkamp said that there were some changes to the RCWD website dealing
with the problem. She also said that she had prepared some
informational pieces that she hoped would be published in local
newspapers soon.
Carp and the impact on the long term success
of the alum treatment was also brought up. Mr. Kocian explained that
carp action is mainly in shallow lake areas and that given the depth of
Bald Eagle that the carp were not likely to impact the area where the
alum will be applied. Some work is being done to study the carp
population in the lake but that current data indicates that the carp
that are present are larger and less likely to cause significant
problems with the alum treatment.
