Overview of Project –Focus Group –Funding –Cooperators –Preliminary Results –What’s next?
Focus Group – April 2008 –Land owners –Tile drain installers –County, State and Federal Agencies County Water board members Soil Conservation District board members and technicians Health Department NRCS RC&D members State Water Commission –NDSU Engineers Soil Scientists Hydrologists
Discussion included –Acres tile drained Do we really know? –Permitting Authority Based on what? –Impacts Water Quality & Quantity Neighbors -Red River – Lake Winnipeg
Discussion included –Reasons for subsurface tiling Increased precipitation Higher water table Earlier access to fields North Dakota Annual Precipitation History
Discussion included –Reasons for subsurface tiling Increased salinity Calcium carbonate Magnesium sulfate Sodium sulfate Franzen 2007

Phase I Yet to do: Assess data Determine information and education for landowners and general public
Phase II COUNTIES SAMPLE 1 TILE DRAIN FOR WATER QUALITY ONLY CASS COUNTY INSTALLS AUTOMATED EQUIPMENT FOR FLOW RATE, WATER QUALITY, AND PRECIPITATION
Phase II COUNTIES CONTINUE SAMPLING 1 TILE DRAIN FOR WATER QUALITY GRAND FORKS, RICHLAND, AND SARGENT COUNTIES INSTALL AUTOMATED EQUIPMENT FOR FLOW RATE, WATER QUALITY, AND PRECIPITATION
Phase II Water quality samples taken at Drain or lift station (automated sampler) Downstream location within a mile from the tile outlet Surface runoff of tiled field (automated sampler) Surface runoff of comparable un-tiled field Flow measurements taken at Drain or lift station (flume/weir) Surface runoff of tiled field (in automated sampler) Soils must be salt affected Soil Samples at 4 sites Rain gauges – Automated or Dewey To determine the effect tile drain effluent from saline soils has on water quality in tributaries of the Red River.
Phase II Project Coordinators and Partners: Work with SCD’s to locate proper sites for sampling Meet with producers as needed Build and/or install equipment Coordinate training of sample collectors and oversee the collection and transportation of samples to the ND Dept of Health Download data from the automated equipment at sites Develop BMPs for landowners Prepare and present results of the assessment to the public
