Monitoring in the Black Hawk Lake Watershed

Black Hawk Lake is an important recreational resource in Iowa. Recently, the lake has had high levels of algae and turbidity. High levels of algae is problematic because it inhibits the natural function of aquatic ecosystems. Turbidity, or the suspension of particles within a water body, also has a negative impact on water quality. The cloudiness within water systems can affect light penetration and can also reduce the volume water systems can hold, and therefore, reduce the space that aquatic habitat can live in. With support from Iowa Department of Natural Resources and other funding sources, such as the Iowa Water Center, we are monitoring the water quality at three sites in the Black Hawk Lake watershed. This is with the goal of determining the effectiveness of strategies used to address the algae and turbidity problems.

Eagle Grove Students Learn about Conservation Practices on the Farm

Eagle Grove, IA – On September 20th, the Earth Science class from the Eagle Grove High School took a field trip to a farm operated by Tim Smith. Smith, a White House Champion of Change for Sustainable and Climate-Smart Agriculture, showed how he incorporates cover crops, strip tillage, and a bioreactor into his farm operation. Students also traveled 12 miles north of his farm to tour a wetland CREP site. Tim, along with Bruce Voigts and Tas Stephen from the Natural Resources Conservation Service (NRCS) in the Clarion USDA office, discussed how the benefits these practices add to soil health and water quality.

Iowa’s Water Crisis: Let’s Talk

We have all come to realize from the recent discourse in the news that water quality can be a bit political. Academic types, like myself, prefer to avoid situations where the political nature of controversial issues are likely to erupt. Last week, the Story County Iowa Democrats hosted a public discussion titled, “Iowa’s Water Crisis: Let’s Talk” in Ames, Iowa. I was invited to be part of the panel discussion alongside Bill Stowe, CEO of Des Moines Water Works, and Seth Watkins, a farmer and Republican from Southwest Iowa. During this event, we had the ‘opportunity’ to objectively discuss Iowa’s water crisis.

Farmers Connect Conservation to Water Quality at Big Spring

Elkader, IA. – On August 10th, fifty farmers from the Upper Roberts and Silver Creek Watersheds enjoyed an evening of family fun at the Big Spring Trout Hatchery along the Turkey River near Elkader. The Second Annual Landowner Appreciation Day allowed farmers and their families to follow the path of water that drains from their land to where it reemerges at Big Spring.

PRACTICES: A tale of grassed waterways

Guest post by John Gilbert of Gibralter Farms, an Iowa Century Farm raising dairy, pigs and crops in the South Fork [Iowa River] Watershed in Hardin County.

The folks of Gehrke Construction, Eldora, and the Hardin County office of the Natural Resources Conservation Service (NRCS) recently finished shaping  what is now Gibralter Farms’ longest waterway.

About 1900 feet in length (three-eighth of a mile), the channel is designed to safely move water that runs off the surface of about 80 acres down 40 feet in elevation to where it can spread out in grass pastures before entering The Southfork, a tributary of the Iowa River.  (The channel will be seeded to sod-forming grass in the spring;  cross-channel fabric checks protect it until then.)  Part of the route has been a waterway for a long time, but recent years of heavier rains have re-enforced the need to control the water all the way across our crop fields.

This is the fourth waterway across this farm moving surface water from the uplands to the north to grass and wetland areas buffering The Southfork, all rebuilt since 2008.  Public money has helped cover half the cost on all but one reconstruction, and could be slightly more than $4,500 on this project.

In addition to the cash assistance, NRCS personnel provided engineering design and layout at no additional cost.  Even after spending 14 years as a commissioner for the Hardin County Soil and Water Conservation District, I’m challenged to explain just what the public gets for their investment in projects like ours.  Obviously, it facilitates getting it done, as it would be harder to budget the whole cost into any year’s expenses, but could be covered by cutting back on other improvements.  Cost share projects are designed to help keep soil from washing, and to protect water quality, and this project will have some benefit for both.

In the final analysis, the benefit is really more one of the public having some involvement in protecting the land, which really is a commonly held resource…one on which we all rely.  Recent trends in farming — with fewer owner-operators and more ownership physically and generationally removed from the land — have eroded (pun intended) the understanding that good soil stewardship is a responsibility that goes with the privilege of using the land.

Farms are not like Vegas; what happens here doesn’t stay here.  What we do as farmers affects us all.  That’s why we’re glad to get this project done.

Most people might not see bulldozed dirt as art, but a well shaped waterway is a thing of beauty.  One more thing to be thankful for.
