Conservation Reserve Enhancement Program (CREP)

Various Locations

ISG partnered with USDA to provide engineering design, construction staking, and construction management services for CREP wetland projects in 13 different Iowa counties. The selected projects were funded through a cost share agreement with USDA and local landowners.

The Conservation Reserve Enhancement Program (CREP) is a major state and federal initiative to develop wetlands which are strategically located using advanced computer technology and designed to remove nitrate from tile-drainage water from cropland areas. Removal of nitrate from these waters helps protect drinking water supplies and reduce hypoxia in the Gulf of Mexico. The program is implemented in cooperation with the USDA Farm Service Agency (FSA) and is available in 37 Soil and Water Conservation Districts (SWCD) in the tile-drained region of North Central Iowa.

Water quality monitoring completed by researchers at Iowa State University has confirmed that CREP wetlands remove 40-90% of the nitrate and 90+% of the herbicide in tile drainage water from upper-lying croplands. In addition to reducing nitrate loads to surface waters, the wetlands will provide wildlife habitat and increased recreational opportunities.
