<br /> Mr. Larry Reschke -3- January 13, 1982 <br />' <br /> 2) A more detailed description of the furrow irrigation mrnthod practiced <br />' in each area <br />information in or adjacent to the permit area must be provided. This p B1 <br />is necessary to decide if this furrow irrigation should be <br /> considered a type of flood irrigation. <br />3) If it is determined that Furrow irrigatiop is not a type of flood <br />irrigation, the Division must consider the potential for flood irrigation. <br />Therefore, the applicant should submit information conrerning the capability p 92 <br />' of the area to be flood irrigated. (See part II of the OSX June Il, <br />1980 Technical Guidance Paper for Alluvial Valley Floor Investigations <br />for additional details.) <br />' 4) The applicant must provide information concerning subirrigation of <br />the lands in question. For these areas adjacent to the permit area, a p, 85 <br />field reconnaissance to identify those areas where the vegetation suggests <br />' subirrigation may be sufficient. For those areas within the permit area, <br />however, site-specific information must be provided concerning crop <br />type, rooting depth, and alluvial water levels during the growing season. <br />if the above information is not provided, the Division wauld go forward <br />with a "worst case" AVF determination. This would likely be that all the <br />area designated ds Qgy is an Alluvial Valley Floor. <br />' THE FOLLOIJING INFORMATION H'OULD DE REQUIRED IF TIlE DIVISION DETERMINES <br />T1lAT AN ALLUVIAL VALLEY FLOOR EXISTS IN OR ADJACENT TO T!!E PERHIT AREA: <br />If Alluvial valley Floors are identified, t/~e applicant must submit site- <br />specific information concerning the productivity of the Alluvial Valley <br />' Floor and [he economic significance of the Alluvial Valley Floor to the p, 9T <br />farm's production. In the absence of actual information, the worst case <br />assumption is that any Alluvial valley Floors are significant to agri- <br />culture. <br />In addition, the application must contain information describing the <br />surface and ground water that supply the Alluvial valley Floor, and <br />' identifying the essential hydrologic functions of the AVF. For any A11u- Pp• 81,85>&9e <br />vial Valley Floor within the permit area, the following must be provided: <br />' 1) One wear's baseline data for the quantity and quality of surface and <br />ground water (tor a perennial stream, gaging stations with continuous p, 37 <br />recorders would be appropriate), <br />2) A description of the exact nature of the hydrologic relationship of <br />surface water and ground water (Iow flow investigations to determine if p• 15,& <br />the perennial stream is a gaining or a losing stream would be appropriate), Figure 7 <br />' and <br />3) A description of the role of subirrigation in the Alluvial Va]Iey Floor <br />including site-specific data on water table fluctuations during the <br />growing season (alluvial monitoring wells equipped with continuous P• 88, Appendix B <br />recorders would be appropriate). <br /> <br />- 5 <br /> <br />
