The Sevenmile and Tenmile Creek Watershed is located in the counties of Adams, Portage, Wood and Waushara. This watershed is a maze of ditches and laterals that were created to drain lowland areas for agricultural activities. There are large sections of land that have been purchased by the state that are being maintained for grassland ecosystems. Both grazing and pivot irrigation are two land uses that impact the water quality of Sevenmile and Tenmile Creeks Watershed. This watershed was ranked using the Nonpoint Source Priority Watershed Selection Criteria. Based on surface and ground water data, the overall ranking is high, establishing Sevenmile and Tenmile Creek Watershed as a high priority for future grant eligibility through the Nonpoint Source Pollution Abatement Program. The watershed includes the towns of Pine Grove, Grant, and Almond. The Portage County Soil Erosion Control Plan identifies these towns as having excessive soil loss rates due to wind and water erosion. There are several cranberry farms located in the watershed that utilize water for their operation. Water drawn from ditches reduces stream flow, decreases adult fish cover, reduces spawning areas for trout and likely exposes fish redds, and may result in an increase of water temperatures. Discharges from cranberry marshes can adversely affect water temperatures, deposit sediment, and release nutrients to the ditches. Periodic impounding of the ditches to flood marshes may prevent fish migration, increase water temperatures and de-water downstream reaches.
