Improvements planned for Allerton mansion pond
by Chris Hermann/Allerton
to recovery The
mansion pond at Allerton Park is shown Nov. 6 partially
drained. Staff members have noticed a marked deterioration
of the pond’s health, so the pond will be fully
drained to aid in diagnosing problems. UI students
in the department of natural resources and environmental
sciences will aid in proposing and implementing a
The mansion pond
and surrounding area are a favorite spot for visitors to Allerton Park.
However, staff members will soon be emptying the pond to better assess
the cause of noticeable deterioration in the pond’s health.
In an effort to identify the causes of these problems and recommend
a solution, Allerton Park and the UI department of natural resources
and environmental sciences have created a unique educational opportunity.
During the next year, UI students will propose and implement a restoration
plan to improve the health of the pond and restore beauty to the pond
As the pond is drained, fish species will be relocated to the Allerton
Diversified Farm Pond. While the pond is empty, research and repairs
will be performed. Data will be gathered on depth and composition of
sediment, contour of the pond, and water flow rates. The student team
and Allerton staff members will remove sediment to restore the original
depth of the pond and plant aquatic vegetation on the banks. If necessary,
repairs will be made to the wall of the dam and pond banks. After completing
necessary repairs and improvements, the pond will be allowed to refill
naturally. When the water level returns to an appropriate depth, the
student team will introduce a diverse fish population to the pond.
The restoration project is scheduled to continue through the summer
of 2004. Visitors will notice ongoing work by both students and Allerton
staff members throughout the research and implementation phases of this
project. These temporary inconveniences will provide long-term benefits
ensuring future health and enjoyment of the pond.
