Water Infrastructure Lifted Conception Rates 50% at SD Award Ranch

Conception rates on Darling Creek Ranch jumped roughly 50% after Dan and Sharon Anderson piped well water across their pastures instead of relying on surface water. That single infrastructure decision, paired with cross-fencing into smaller paddocks, sits at the core of the operation that won South Dakota's 2026 Leopold Conservation Award, announced in the award cycle dated November 12, 2026.

The Andersons run about 200 cows and 1,400 ewes near Meadow, S.D., with their youngest daughter Danessa on the ranch and three older daughters working part time. The conservation ethic started with Dan's parents, Jim and Nora Anderson. Dan credits most of the ranch's progress to a simple loop: try something different, measure it, adjust.

Why did water development move the needle so hard?

Smaller cross-fenced pastures cut the distance breeding males had to travel, while frequent pasture moves kept females on higher-quality nutrition longer. The result: that 50% conception lift across both cattle and sheep. The ranch's target now is water within about a half mile in every pasture. Aboveground drag lines and mobile skid tanks move water with the livestock, so grazing rotations aren't designed around permanent tank sites.

Fencing for the sheep side is cheaper than newcomers expect. The Andersons skip woven wire entirely, using electric polywire with temporary step-in posts plus high-tensile electric wire on permanent fiberglass posts. The key, Dan said, is having the right fencer. They acclimate sheep to electric fence shortly after shearing, when shorn animals feel the wire more readily. For first-time sheep buyers, he recommends middle-aged ewes over yearlings or older animals — they're more resilient.

What does grazing management look like in practice?

There are no designated "summer" and "winter" pastures on Darling Creek Ranch. Any pasture can be grazed in any season, and varying the season of use is, in Dan's view, one key to maintaining plant diversity. Livestock never stay in one pasture longer than two weeks. At times cattle move daily or every couple of days under high-stock-density mob grazing.

Longer rest periods have brought natives back, including winterfat (Krascheninnikovia lanata), a high-protein forb valuable for winter grazing. Bailing-grazing trials on clay hardpan — concentrating hay and livestock on the same ground — have added organic matter, built soil from the top down, improved infiltration and fed soil microbes. Soil 30 feet away from a bale-grazed patch, by contrast, lacks that organic matter and structure.

Can a ranch run like a business?

The Andersons say good land management requires good business management. Their operation runs as a limited liability company with mission and vision statements and defined family roles. They hold a one-hour business meeting every month, separating day-to-day ranch work from decisions on finances, goals and succession.

Mistakes get treated as data. "A learning opportunity to step back and look at it again," Dan said. They also keep a standing drought plan — not a rigid script, but a starting point they adjust as conditions change. His advice to other producers: "Start small. Try something different. See if it works."

Which extra strategies are paying?

• Vinegar supplementation. Fed in the drylot and on pasture, the Andersons' own trials suggest it has cut feed needs by about 20% by helping animals extract more nutrition from forage as it matures and lignifies (develops the tough fiber of older plants).
• Custom grazing. They custom-graze outside cattle from summer through Nov. 1, then transition those pastures to winter grazing for their own herd — a second income stream from the same grass.
• Water-tank loafing control. Small watering areas, sometimes with a hot wire, push cattle to drink and walk back out to graze rather than congregation around tanks and creating bare ground.
• Guardian and herding dogs. Six livestock guardian dogs — Dan favors Akbash breeding for athleticism and wide patrol range — plus three border collies, combined with keeping sheep in smaller groups, have cut predator death loss from about 10% to under 2%.
• Mobile supplement stations. Another tool for steering livestock distribution across paddocks.

The Andersons also work with the U.S. Forest Service, a local grazing association, the South Dakota Soil Health Coalition, the South Dakota Grasslands Coalition and USDA Natural Resources Conservation Service, and they host a summer intern each year to show how conservation and production coexist on a working ranch. Ranchers wanting to replicate the model should watch the Leopold Conservation Award's state-level application windows — and start, as Dan puts it, small.
