<br />n '" 706 <br />v I.! ~ :J) <br /> <br />2522.12c <br /> <br />. <br /> <br />TITLE 2500 - WATERSHED MANAGEMENT <br /> <br />e <br /> <br />2522.1 - Watershed Improvement Activities. Watershed <br />improvement activities are land treatments or management <br />measures implemented to improve watershed condition. <br /> <br />2522.11 - Watershed Condition Improvement. Install land <br />treatment and structural measures to reduce erosion, <br />stabilize land mass movement, and provide for favorable <br />conditions of water flow. Measures include vegetative and <br />mechanical sheet erosion control; rehabilitation of aban- <br />doned roads and trails; streambank, gUlly, and lakeshore <br />stabilization; stream channel clearing, sediment basin <br />construction and other activities designed to stabilize <br />watersheds. <br /> <br />2522.12 - Water Yield Enhancement. Water yield enhancement <br />includes the fOllowing activltles: <br /> <br />e <br /> <br />2522.l2a - MOdified Timber Harvest. Modification of timber <br />harvest techniques can lnfluence the deposition and melt of <br />snow. When developing timber harvest plans in water short <br />areas, consider mOdifying harvest procedures to increase <br />water yields. Where Forest plans indicate both a need for <br />increased water and available storage to recover the <br />increased yield, evaluate opportunities to enhance existing <br />water supplies. Implement enhancement practices only if <br />cost-effective, environmentally feasible, and consistent <br />with other resource uses and values. ___ <br /> <br />e <br /> <br />2522.12b - Weather Modification. Support properly designed <br />and technically sound snow augmentation or other weather <br />modification activities carried out by cooperators, pro- <br />vided those activities and anticipated results are consis- <br />tent with any applicable law or regulation governing the <br />administration and management of National Forest System <br />lands. See FSM 2323.44 for weather modification policy <br />over wilderness. <br /> <br />2522.12c - Type Conversion. Do not permit the conversion <br />of vegetative types for the purpose of increasing water <br />yields, until such is proved to be environmentally sound, <br />cost effective, and can meet the objectives of National <br />Forest Management. <br /> <br />e <br /> <br />*-FSM 3/86 AMEND 48-* <br />
