The Ten Mile River Preserve is located on the east side of Marion Avenue between Jarvis Street and Roger Avenue.  It is bounded to the south by the Town of Cheshire's Casertano Property, and a small piece borders the Ten Mile River to the east.  

 

The Judd Brook Preserve contains two parcels, one to either side of Knotter Drive, both south of West Johnson Avenue.  (The Judd Brook Preserve is one of several CLT preserves actually made up of multiple parcels.) The Quinnipiac River Watershed Association has described Judd Brook as "a high quality permanently innundated floodplain swamp preserve."

Both properties are named for watercourses important to the Cheshire landscape.

 

The Ten Mile River watershed drains much of northwestern Cheshire.  Judd Brook is a tributary to the Ten Mile that starts in Southington.  

 

Another major tributary is Cuff Brook.  The Ten Mile River's mainstem and surrounding areas contain a high level of biological diversity that has been extensively studied by QRWA and other organizations.  In particular, scientists have been interested in the area's reptiles, amphibians, freshwater mussels, and numerous vernal pools.
