Controlled drainage is a drainage technique that uses stoplogs or flashboards to dam outflowing drained water. The result is a rising watertable which keeps the soil appropriately saturated for optimal growing.
The results are clear and simple enough: keeping the water table at plant root improves yields (25–60 bu/ ac), decreases expenditures on fertilizers (~30%) and decreases the dependency on inefficient irrigation techniques during periods of limited rainfall.
At Fratco, we take environmental responsibility seriously. We’ve been wedded to the earth for nearly a century and we’re here to protect it. Controlled drainage can decrease water outflow by 20%, nitrate losses by 45% and phosphorus runoff by 35%. These drastic reductions carry a huge positive impact on the surrounding environment.

Most likely. Most drainage professionals would be able to assess your system and develop a plan to retrofit a controlled drainage structure. Even if you have clay in the ground.
Yes. Programs from NRCS (554 and 587). EQIP, CSP, CRP and CREP all may provide help with the initial costs of installation and equipment.
Typically 10–20 acres can be adequately controlled with one management structure.
