Trustees authorize interim repairs and debris-catching structure for DD 1-25 '4-bay' pond
Summary
Following engineer review and discussion of responsibility for long-term maintenance, the trustees authorized immediate ballast/structure work to slow erosion and ordered a locally fabricated debris-catching box to be built and staged for installation.
Trustees for Drainage District (DD) 1-25 reviewed engineering observations and photos of an existing four-bay sediment pond that is filling with field debris and risking washout of downstream infrastructure. After reviewing a letter from the district engineer noting there is no formal recorded agreement requiring the district to maintain the larger NRCS-constructed pond, trustees authorized immediate work on the district-owned 4-bay structure to reduce the chance of further erosion.
Why it matters: The 4-bay pond receives surface runoff and large amounts of crop residue. If the intake or the 4-bay erodes or plugs during heavy rain, the roadway and downstream ponds could be damaged. Trustees agreed to act now to limit further damage while the county and counsel continue to clarify long-term maintenance responsibility.
Staff summarized field observations: an intake grate and downstream pipe are partially plugged by cornstalks and debris that arrive from a steep field above the road. Trustees discussed edge-of-field practices and agreed that some solutions require landowner cooperation; they identified available conservation programs that could incentivize grassed waterways or buffers to reduce future inflows.
Action taken: Trustees approved a motion to fabricate and install a heavy, permanent debris-catching structure (described in the meeting as a large cone-shaped or pyramid rock/metal structure sized to the existing 4x4/5x5 box intake). A locally available fabricator was identified (named in discussion as “Paul”); trustees moved and seconded a work order to have the box constructed and staged for installation. The motion carried by voice vote.
Engineer's recommendation: The county engineer provided a letter recommending no further expense on the larger (NRCS) pond until responsibility for future maintenance is clarified; trustees accepted that recommendation but authorized targeted, district-owned repairs to the 4-bay to avoid imminent washout.
Ending: Trustees asked staff to coordinate site visits, ask the engineer to specify required rock sizes and installation details, and to discuss edge-of-field conservation options with the landowner. The fabricator will be given site instructions and the trustee-designated contractor will install the debris-catching structure when ready.
