<br />5. The project's impact on ponds, sloughs, streams, or lakes having <br />recognized fish and wildlife values. <br /> <br />According to the general literature, runoff from tile drainage tends to have low <br />turbidity, be low in total suspended solids, and have lower total phosphorus <br />concentrations than surface runoff. Nitrate and salt levels tend to be elevated, <br />However, the general literature appears to suggest that salt concentrations in tile <br />flow are typically transient, and they drop off over time. Elevated nitrate levels <br />may accelerate eutrophication of downstream water bodies. <br /> <br />6. The project's impact on agricultural lands. <br /> <br />The purpose of the project is to improve agricultural land where the tile is <br />installed. However, adverse impacts to downstream agricultural lands will likely <br />occur in the form of prolonged wetness in downstream channels. This condition <br />may promote the growth of cattails in downstream channels causing an adverse <br />impact to downstream agricultural drainage. In addition, the prolonged wetness <br />may cause channels to become impassible for agricultural equipment. Lastly, <br />there may be a transient salt impact to downstream agricultural lands adjacent to <br />the channel. <br /> <br />7. Whether easements are required. <br /> <br />As set out by the Rush River Water Resource District. <br /> <br />8. Other factors unique to the project. <br />Conditions placed on the project by the State Engineer and Rush River WRD. <br /> <br />2 <br />
