species initially. When this occurs, and the period before establishment of permanent irrigated <br />pasture will extend beyond a year, Seed Mix #3 - Temporary Reclamation will be used. This mix <br />will provide interim stabilization as well as organic matter benefits when incorporated during <br />tillage and seedbed preparation prior to seeding of the irrigated pasture seed mixes. <br />Prior to final seedbed preparation, soil conditioning and weed control tillage will be carried out <br />through the use of chisel plowing and disking. Chisel plowing will relieve topsoil compaction, <br />aid in controlling weedy species, and will leave the site in a temporary roughened condition <br />reducing wind and water erosion potential. Disking may also be used to condition soil, break up <br />clods, and control weeds through tillage prior to seeding. If annual weeds are a problem, several <br />tillage operations may be required to get adequate control. Harrowing and cultipacking prior to <br />seeding will be conducted as needed in order to provide the smooth, firm seedbed required. In <br />any areas that may be poorly drained, tillage will be timed in order to reduce bogging, excessive <br />compaction and excessive cloddiness caused by tillage when soils are wet. The best period for <br />tillage in these areas may be in the early spring prior to the irrigation season (prior to mid - April). <br />Section 2.05.4(2)(d), Topsoil (Redistribution), contains additional information on subsoil and <br />topsoil conditioning. <br />Irrigation Designs <br />Areas that are to be reclaimed as Irrigated Pasture or Intensively Managed Irrigated Pasture will <br />be irrigated using either sprinkler irrigation or flood irrigation. Map 2.05.5 -1 shows all areas <br />which will be reclaimed as Intensively Managed Irrigated Pasture or Irrigated Pasture on the <br />Garvey property. <br />The calculations for both flood and sideroll sprinkler irrigation are shown in Attachment <br />2.05.4(2)(e) -1 for the reclaimed Irrigated Pasture and Intensively Managed Irrigated Pasture. <br />These calculations were made using the irrigation design worksheets from the Colorado <br />Irrigation Guide and the NRCS National Engineering Handbook Sec. 15, Chap. 11. Flood <br />irrigation will be supplied by 4 inch to 10 inch supply lines. The extent of irrigation on the <br />Garvey property will be based on the amount of shares that are available to them from the CCC <br />Ditch for this area. The designs are based on the NRCS calculations with accounting for 6 days <br />Section 2.05.4(2)(e) Page 2 January 2012 <br />
