Farm ponds, retention ponds, swimming ponds, and water feature excavation. Full site work from clearing to final shaping, dam and berm construction, and inlet/outlet installation.
Backwell excavates ponds for farm operations, residential properties, commercial sites, and stormwater management systems throughout Marathon, Cortland County, and the surrounding area. Whether you need a new farm pond for livestock watering and irrigation, a retention basin for a development project, or a recreational swimming pond, we bring the equipment and expertise to get the excavation done right.
Proper pond construction requires more than just digging a hole. We evaluate soil permeability, establish the right depth profile for your intended use, engineer the dam and spillway to handle your watershed, and install inlet/outlet structures to manage water levels. Our team handles all associated earthwork including clearing the site, shaping the basin, constructing the dam and berms, and final grading of the surrounding area.

Marathon lies in the Tioughnioga River valley in southern Cortland County, on a narrow outwash-floored corridor cut into the Appalachian Plateau. The valley floor carries Chenango gravelly loam and Howard gravelly loam — well-drained and cobble-rich — while the valley walls climb steeply into Lordstown and Mardin channery silt loams on fractured sandstone and siltstone.
The Tioughnioga River runs through the village and drains south toward the Susquehanna, and the valley's sole-source aquifer status imposes stricter stormwater and infiltration protection on any commercial project. Site work in Marathon consistently involves cobble-heavy trenching in the outwash, rock excavation on the valley walls where development climbs out of town, and floodplain management along the river corridor. The I-81 interchange area sees most of the commercial activity, and earthwork there typically requires aquifer-protection measures as well as standard erosion and sediment controls. Frost depth is substantial given the upstate interior climate. Projects near the Tioughnioga River fall under NYSDEC stream-protection review in addition to municipal permitting, and the narrow valley limits lay-down area on most commercial sites.
