• possibly alluvial valley floors. These areas, shown on Map 5, Fish <br />Creek Tipple Hydrology, are: 1) the Middle Creek floodplain; and 2) <br />the Fish Creek floodplain. The information provided under this Rule, <br />along with information provided under Rule 2.04 and 2.05 in this <br />application, documents the characteristics supporting the essential <br />hydrologic functions of affected alluvial valley floors in the <br />proposed permit and adjacent area. <br />Based on the information accumulated in the reconnaissance and field <br />investigations and the baseline data collection program, the effects <br />of the existing tipple operation and the proposed reclamation plan on <br />alluvial valley floors downstream from the proposed permit area have <br />been evaluated. The possible direct and indirect effects of the Fish <br />Creek Tipple on the essential hydrologic functions of the two <br />applicable subject areas which may contain alluvial valley floors are <br />discussed. Supporting data used for the material damage determination <br />are summarized in the discussion, and can be reviewed under the <br />• following Rules: <br />Geologic data (from Rules 2.04.6 and 2.06.8 (3)). <br />Soils and vegetation data (from Rules 2.04.9, 2.4.10 and 2.06.8 <br />(3))• , <br />Surface water data (from Rule 2.04.7 (2) and 2.06.8 (3)). <br />Ground water data (from Rules 2.04.7 (1) and 2.06.8 (3)). <br />Operations and reclamation plan (from Rule 2.05.3 and 2.05.4). <br />Agricultural land use (from Rule 2.04.3 and 2.05.5). <br />The following discussion is divided into six major subheadings: <br />Essential Hydrologic Functions; Agricultural Significance; Potential <br />Material Damage; Effectiveness of Reclamation; and Environmental <br />Monitoring. <br />The two subject areas, the floodplains of Middle and Fish Creeks, are <br />historically or currently flood-irrigated.
