The Natural Resources Conservation Service awarded the Rathbun Land and Water Alliance $221,550 through their Iowa Partners for Conservation Grant. The funds will be used to expand the scope of conservation practices used by Rathbun Lake Watershed landowners during a five-year award period ending in 2023. 

A list of some of the Best Management Practices promoted through the grant period are listed at the bottom of this article. 

Since 2004, the Rathbun Land and Water Alliance has partnered with supporting agencies, organizations, and Rathbun Lake Watershed landowners to implement soil saving and water quality protection practices.

During this time, more than 600 landowners in the Rathbun Lake Watershed counties of Appanoose, Clarke, Decatur, Lucas, Monroe, and Wayne have worked with the Alliance to apply conservation practices on 30,000 acres.

These measures have been successful, resulting in the reduction of annual sediment delivery to Rathbun Lake by 57,000 tons per year and 249,000 pounds of phosphorous.

Rathbun Lake is the water source for Rathbun Regional Water Association’s 90,000 customers who rely on the lake for their drinking water.

In addition to the IPC grant, $235,125 is provided by the Alliance and supporting partners which includes the Iowa DNR and ISU Extension.

John Glenn, RLWA president and CEO of Alliance partner RRWA says most of the conservation practices applied to date have been structural measures such as terraces, grade stabilization structures, and water and sediment control basins.

“This funding serves to strengthen conservation efforts in the watershed by broadening the range of practices used by landowners,” states Glenn. “These practices include conservation cover, crop rotation, cover crops, forage harvest management, forage and biomass planting and prescribed grazing.”

Rathbun Lake Watershed Coordinator, Brian DeMoss, is an environmental specialist with the Lucas County Soil and Water Conservation District. He says this funding gives landowners more options with converting some of the land that came out of marginal pasture and went to row crop in 2012-2013 when commodity prices were high, and get them back to a pasture/ hay setting. 

“These practices address resource concerns in the watershed related to soil health, grassland performance, and wildlife habitat as well as water quality,” explains DeMoss.

Funding also provides for ten field days and workshops, and to disseminate water quality protection updates.

“This gives producers a few more options to consider that work hand in hand with the structural measures that they install on their lands. I always look forward to working with landowners and encourage them to contact me,” says DeMoss. He can be reached at the Chariton field office at 641.774.2512.

  1. I think I read something about an uptick in global CO2 levels that didn't show up in the records from previous inter-glacial cycles existing that happened around the same time that agriculture was first developed in the fertile crescent and the earliest rice farming regions in eastern Asia. If I'm remembering right that'd be a first global impact from thousands of years before the Maya, although it'd still be human land use driven.
