The Joliet Junior College Lake is a central aesthetic feature of the main campus. The 5.8 acre lake has a 362 acre watershed which includes the college campus; parking lots; wooded, farm and open fields; and residential and commercial developments.
A grant-funded rehabilitation project is underway to restore the natural beauty and ecological health of the JJC Lake. Fertilizers, pesticides and herbicides from surrounding lawns and agricultural fields flow into the lake through storm water runoff. Nutrient-rich sediments accumulate, causing an explosion of plant and algal growth. This depletes oxygen levels, which leads to fish kills. The accumulation of sediment has also reduced the lake's water-holding capacity by 20 percent. The rehabilitation efforts will address these issues with the goal of restoring the quality, health and natural beauty of the lake.
- 6,300 cubic yards of sediment will be dredged from the lake and distributed on the college's agricultural fields; after dewatering, the nutrient-rich sediment will be spread over the Ag field
- Best management practices (BMP's) will be established and implemented to reduce non-point source pollution and ensure the long-term health of the lake
- Separators and Wetland Swale will be installed to filter runoff water from the parking lots
- Bioswales and a Bio-Filter Cell will be installed to filter runoff water from agricultural fields, grass fields and residential areas before it enters the lake
- Native plant species will be planted along the shoreline to prevent soil erosion
- Unsightly floating debris, odor problems and sediment buildup will be reduced
- A clean, healthy habitat for fish, wildlife and native plant species will be restored
- Approximately two feet will be added to the depth of the lake on average, restoring the lake's water-holding capacity
- Education and research opportunities will be increased
- This campus asset will continue to provide an outdoor laboratory for JJC faculty & students
Funding for this project provided, in part, by the Illinois Environmental Protection Agency through Section 319 of the Clean Water Act.
JJC Lake Serves The Campus, Community and Watershed
The JJC Lake has been subjected to stress due to urbanization and natural factors. If the lake is not properly managed, or if properties that drain to the lake contribute pollutants, the functions of the lake can be significantly degraded.
Property owners within the lake watershed can actively participate in the preservation of the lake. The following benefits are provided by the lake:
- Recreation, open space, and diverse plant and animal habitat
- Pleasing environment
- Vibrant fishery and fish habitat
- Flood control and stormwater management
Fertilizers, pesticides and herbicides applied to lawns, agricultural fields, or properties can end up in the lake. These chemicals can be carried during rainstorms in drainage water that ultimately drains into the JJC Lake. These chemicals and nutrients have a significant impact on the quality of the lake, contributing to noxious plant growth, fish kills, and algae blooms and die-offs. Organic sediment deposits have reduced the original lake water volume by 20 percent. Soil eroded during rainstorms also finds its way into the lake. As a result of these factors, the lake depth has been reduced by one to two feet.
What You Do on Your Property Can Dramatically Affect Lake Water Quality
The JJC Lake is a living body containing many organisms. When these organisms are in balance, the water quality is good, the lake is clean and attractive, and fish and wildlife habitat are abundant.
JJC Lake is periodically out of balance resulting in excessive algae growth causing:
- Unsightly floating debris
- Odor problems
- Sediment buildup
Lake algae growth can be impacted by watershed land management activities. Following is a typical algae growth cycle:
- Rain water leaving your property ends up in the lake.
- Excess fertilizer, pesticides, and herbicides applied to lawns finds its way to the lake and degrades water quality.
- Eroded soil and organic sediment in the lake bottom have reduced the lake volume by 20 percent in 30 years, and depths are one to two feet less than historic levels.
- Animal waste, sediment, de-icing salts, oil and grease from impervious or agricultural lands can find their way into the lake.
- Fishkills have occurred as fish are choked by oxygen shortages caused by water quality problems.
What Can You Do to Help Protect and Restore the JJC Lake?
You can have a significant beneficial impact on lake water quality and appearance. The following actions will make a big difference:
- Use fertilizer with no phosphorous content if possible (10-0-10 nit-phospot ratio), or lowest phosphorous level available. Use a max. application rate of one pound nitrogen per 1,000 ft2. Limit applications to a max. of four times each season.
- Do not apply fertilizer before or after heavy rainfall. Lightly soak fertilizer with each application. Use granular instead of liquid fertilizers.
- Keep dead leaves and animal waste out of drainage swales and the lake.
- Report soil erosion to JJC.
- Minimize agricultural pesticide and herbicide applications.
- Keep your driveways and sidewalks free of oil, grease and other suburban pollutants. Maintain your vehicles so they don’t leak fluids.
- Become familiarized with your watershed. The committee has a detailed report on file for your review.
- Minimize use of deicing chemicals.
These simple steps will help improve future lake water quality. JJC is doing its part by investigating methods to mitigate problems caused in the past.
Our 11-acre arboretum is located on JJC's 368-acre Main Campus, between the entrance and exit roads, adjacent to Houbolt Road at the main gate. It is a place where woody plants, trees, shrubs, and vines are grown for exhibition and study.
The college arboretum concept was originated by Dr. William M. Zales in 1975 as part of a master campus use plan. Upon Dr. Zales's retirement in 1999, the arboretum was renamed in his honor to recognize his contributions. The master plan includes development of nature trails, restoration of native ecosystems, such as the prairie, fen, various stages of forest successional types, soil conservation measures for the agricultural crop land, and management plans for the campus lake.
These continuing projects are managed by the JJC Natural Areas Committee, the Grounds Advisory Committee, and the college's building and grounds staff. In the spring of 2004, the JJC Foundation and Alumni Relations (The Office of Institutional Advancement) and the Natural Area Committee launched a new project called Trees for Tomorrow to raise funds for the continued development and maintenance of the arboretum.
Funds from the Friends of the Arboretum will be used to purchase and plant trees for the arboretum. These outdoor facilities are used and enjoyed by students both in and out of the classroom, as well as by faculty, staff and community members from throughout the district.
Trees for Tomorrow
Joliet Junior College invites you to become a member of Friends of the Arboretum, which works to improve and diversify the 11 acre arboretum at Joliet Junior College's Main Campus.
The Dr. William M. Zales Arboretum is intended to serve JJC students, faculty, staff, and the community as a unique educational resource. Dr. Zales retired from JJC in 1999 after having served the college for over three decades. The arboretum was named in his honor.
Please help us make JJC's arboretum the living laboratory Dr. Zales intended it to be. We would like to increase the number and diversity of plantings to include more than 200 species belonging to more than 100 genera in approximately 50 families. Our vision is to create a park-like setting with winding footpaths, benches, and educational information about the native and naturalized woody plants growing in the arboretum.
Your tax-deductible donation will allow you to become a member of Friends of the Arboretum and will enable the college to make the needed acquisitions to develop and maintain the arboretum well into the future. Trees will be added to the arboretum in the spring and fall seasons of each year.
