Ponds
Our neighborhood ponds are part of the stormwater system and a valued open-space amenity. The HOA manages shoreline care, water-quality services, and safety rules to keep these areas clean and enjoyable.
About the Ponds
These basins collect and slowly release stormwater to reduce flooding and protect water quality. Vegetated buffers stabilize shorelines, filter runoff, and support wildlife. Please enjoy the views and paths while respecting posted rules.

Frequently Asked Questions
Who owns the ponds in our neighborhood?
The neighborhood development firm (Mahomet Land Company) currently retains ownership of the ponds until completion of the final phase (Phase 7) of Thornewood. The HOA Board remains actively engaged with both the developer and the Village of Mahomet throughout this transition period. Once development is complete, pond ownership will be legally transferred to the HOA Board.
In the meantime, the Board contracts with professional firms to maintain water quality and shoreline vegetation. The developer continues to make physical improvements to the ponds, including having previously installed a shallow “safety shelf” around the perimeter to minimize drowning risk, and recently implementing erosion control measures.
Who maintains water quality in the ponds?
The HOA Board contracts with qualified pond management vendors who specialize in stormwater and ecological balance. The Board also seeks guidance from experts to maintain a sustainable approach that supports water quality, environmental stewardship, wildlife habitat, and visual appeal. The goal is to preserve the ponds as both a functional stormwater system and a valued natural feature of the neighborhood.
Why is there so much vegetation along the pond edges?
The HOA follows recommendations from aquatic management specialists, including University of Illinois Extension and IDNR professionals, to promote pond health and sustainability. Vegetated buffers stabilize shorelines, filter runoff, reduce erosion, and discourage nuisance wildlife such as geese. These native plants are intentionally left in place to protect water quality, maintain habitat, and support long-term ecological balance.
Can I fish in the ponds?
Yes, fishing is permitted for residents and their invited guests who are associated with a Thornewood HOA property owner. All Illinois Department of Natural Resources (IDNR) licensing and regulations must be followed. Catch and release is strongly recommended, and fishing is allowed only from the shoreline. Flotation devices such as kayaks, canoes, or boats are not permitted. Learn more about IDNR fishing requirements.
Is it safe to walk on pond ice in winter?
Absolutely not; walking on frozen ponds is extremely dangerous and strictly prohibited. Ice conditions vary due to inflows and aeration, making thickness unpredictable. During initial neighborhood development, a shallow “safety shelf” was built around each pond to reduce drowning risk; however, residents must remain vigilant. Always supervise children and pets near the ponds, and never attempt to walk or play on the ice.
Who should I contact if I have a question/concern about the ponds?
If you notice issues such as erosion, algae blooms, or damaged equipment, or if you have a general question about pond maintenance, please contact the HOA Board by email at thornewoodhoa@gmail.com. Your message will be directed to the appropriate Board member or vendor for follow-up.
