IGWA's annual publication with articles on

Iowa water resource topics and issues


Iowa has been battling the problem of agricultural nutrients for decades.  Many feel that progress has plateaued or regressed because of agricultural economic conditions, the pervasive use of agricultural drainage tiles, and the increased amount of land being placed into production. 


For a pragmatic perspective on the topic of nutrients and water quality, IGWA invites you to read Bob Drustrup's article Nutrients in Iowa's Waters  

Other Readings on Agricultural Drainage   

Water – A Resource Drained Away - An excellent historical look back at how agricultural drainage has changed Iowa's landscape.
Agricultural Drainage Tiles - An overview of their use, benefits, and
effect on hydrology and water quality.
