Watershed, drainage woes linger from statehood days
By Jessica Giard
The 19th-century explorer John Wesley Powell wanted to draw the political boundaries of the arid American West based on watersheds, to avoid fights over water.
Powell, who is best known for his expeditions on the Colorado River, thought the boundaries-by-watershed concept would push water users — specifically those engaged in agriculture — to be more efficient with water.
Lavey, a land-use planner for the Sonoran Institute, recently created a full United States map depicting what that kind of nation that might have looked like. Around the James River Valley especially, the boundaries would have been vastly different.
Powell’s watershed boundary vision did not come to pass, but the conflicts he envisioned did — including here in the Dakotas.
In eastern South Dakota, changing land use coupled with a wetter climate has challenged water management across landowner, county and state lines.
No clear system exists, at any level, to look at how to most effectively and efficiently manage the water, specifically flood control and drainage, across those lines.
“It’s just a haphazard, non-uniform system right now,” said Mike Traxinger, legislative director with South Dakota Farmers Union.
Over the past year, Traxinger has worked to learn the political issues surrounding watershed management.
He’s learned there is a desire for a fair and uniform system that also allows for local control but not too much regulation — desires that require careful balancing, since they could easily conflict.
“There is a fear of over-regulation but there are benefits to understanding what’s going on throughout the watershed,” he said, and the greater question is, “can you develop a tool to help people understand these issues?”
Who gets to decide
Currently, drainage issues are managed on a county-by-county basis, and that is sometimes hit-and-miss. Not all counties manage drainage. The counties that manage drainage often operate differently. And in the past 20 years, Traxinger said counties have shied away from regulating drainage. Decision-making can be costly between the need to hire a professional engineer to understand the drainage and the fear of liability.
Another challenge in creating a watershed management district stems from crossing the jurisdictional boundaries. How do you determine who gets to vote for leadership in a watershed that spreads across multiple counties?
The bottom line is that the water has to go somewhere, regardless of political boundaries. Traxinger envisions a sort of hierarchal system that allows control at the local, regional and state levels.
“If there was an ideal situation, it would be you would have very much local control within a watershed,” he said. “But then there would be ways in which these watersheds could communicate with each other. Plan, develop projects and really have a focus across the state. That, to me, takes a huge amount of leadership at the state level.”
At the state level, two bills (SB 169 and SB 160) proposed in the 2012 South Dakota legislative session to address watershed management in eastern South Dakota were essentially mashed up to create the 14-member regional watershed task force for a three-year study of eastern South Dakota.
Land use affects water
Brad Johnson, a former member of the watershed task force and current chairman of the state Board of Water and Natural Resources, is most interested in flood control and water quality, though the task force is looking more at flood-related issues.
The flood-related issues have become exacerbated by a wetter climate and changing land use in eastern South Dakota. As producers shift to more corn and soybeans, water runoff has increased compared to previous stronghold crops like wheat, oats and flax.
“The change to corn and soybeans means the land will not hold water like it used to,” Johnson said. “Studies have shown, particularly along the Big Sioux River, the river responds much faster to a rain event than it ever used to, which leads to the increased frequency of floods.”
Producers are pushing for more acreage, therefore installing more drain tile, which increases run-off and flood potential. Johnson, who also works as an appraiser in the Watertown area, realizes the economic value of installing drain tile on ag land, but he doesn’t like it.
“We have a tremendous amount of land that now has drain tile installed. And that’s all trying to move the water off the land and into the rivers and downstream,” he said. “The result is that you’re going to have fewer wet areas in fields but you’re going to have either a constantly flowing river or you’re going to have centralized water bodies that grow bigger.”
This puts communities at risk, not only for flooding but also for pollution and water quality issues. Further, the change in crops and increased drain tile also affects wildlife, he said.
“If you take a look at the drainage issue, we presently do not have any mechanism in this state to determine what’s really happening out on the land. We don’t know what the effect of all these different systems is having.”
