Location: The JD 19 watershed is primarily located in Hunter and Heron Lake Townships. The ditch lies directly east of and adjacent to the City of Lakefield. The JD 19 mainline tile begins in Section 12 of Hunter Township and spans across Sections 2, 3, 11, and 12 of Hunter Township and Section 34 of Heron Lake Township where it oulets into an intermittent stream which leads into Jackson County JD 3. Other tile branches drain land from Section 34, 35, and 36 of Heron Lake Township; Sections 1, 2, 3, 10, 11, and 12 of Hunter township; and Section 6 of Des Moines Township.
Size: The JD 19 watershed provides drainage to approximately 3,179 acres.
Project: The goal is to abandon and replace the entire JD 19 main tile along with 26 branches. The improvement will achieve a drainage coefficient of at least 0.50 inches per day for the underground tile main and branches. A pond will be constructed at the main outlet on land owned by the City of Lakefield. The pond will encompass a total of 5.9 acres, including 16.5 foot buffer strips and will provide 39.26 acre feet of storage to keep the flows from larger rain events in check.
Portions of the JD 19 system drain into a wetland within the Toe Wildlife Management Area (WMA). A Conservation Partners Legacy Grant from the Department of Natural Resources for $21,661 was secured to complete a 62-acre wetland enhancement project on the Toe WMA on the JD 19 system.
Estimated cost: $3.8 million, financed by general obligation bonding through Jackson County.
Status: The bid was awarded to Svobda Excavating, Inc. on February 13, 2019. Construction began in 2018 and continued through 2019.
JD 19 Construction Update.
• Eighty six percent of the project is complete. A substantial amount of the work was done in 2019. The northeast part of the watershed remains to be completed. These are small branches with shallower tile installation. There is one transmission line that still needs to be crossed. The contractor stopped work on January 13. Svoboda Excavating plans to start in early spring and finish the project. ISG will start televising the week of February 24. The completion date for this project is May 30, 2020.
• The county is going to do some work on the outlet of the small pond.
• The wetland outlet structure is in place. The contractor also hit some poor soils in this project. They are getting close to using the amount of rock estimated.
• There was one issue boring under County Road 14. A dip in the road was discovered. There was a void under the road. The contractor fixed this at no cost to the project.
