Summary

After reviewing a Houston Engineering memo, the drainage authority voted to take no ditch‑funded action on Ditch 44 at Head Lake due to unstable soils and limited elevation benefit; the board also dismissed Ditch 30 proceedings and will reimburse prior assessments totaling $39,067.73 (with 4% interest calculated to $52,833.42).

The Otter Tail County drainage authority reviewed two ditch matters on Oct. 14 and took separate actions.

For Ditch 44 at Head Lake, Houston Engineering reported peat soils up to 5–7 feet with no hard bottom, making extensive soil import or earthen berm construction impractical. The consultant presented three scenarios: (1) do nothing (recommended); (2) install sheet piling/vinyl piling to form a weir (feasible but likely to require annual maintenance and offer minimal elevation change); (3) remove unstable soils (impractical given cost). The county engineer and commissioners discussed the limited water‑level benefit and maintenance burden; the board moved to leave the ditch as is and not expend ditch funds on major repairs.

On Ditch 30, staff reported the ditch was never established or constructed; assessments and prepayments from property owners from various years total $39,067.73. Including 4% interest, the total to reimburse would be $52,833.42. The board ordered dismissal of the ditch proceedings, termination of assessments and county‑supported repairs, and authorized sending letters to affected landowners to request acknowledgment before issuing reimbursements; the board conducted a roll‑call vote and carried the motion.

County staff said letters and reimbursement checks will be mailed as acknowledgments return.
