Improvements planned for Allerton mansion pond

Photo by Chris Hermann/Allerton Road 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 restoration plan.

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 area.

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.
