<br />WA TERSHED PROBLEMS fIND NEEDS <br /> <br />Streambank erosion has been a continuing problem for <br />this area, The loss of arable and farmed land, loss of <br />riparian areas, loss of and damage 1;0 irrigation structures, <br />and damage to bridge embankments ara examples of types of <br />damages occurr i ng approx imate I y 2 11 i I es of the study an,a, <br />Approximately 91 acres of pastureland, hayland, trees, <br />homesteads, and riparian areas that are adjacent to the <br />study areas, including 1 bridge, 1 house, and 1 divers on <br />[SEE LOCATION MAP AND TABLE 1J. <br /> <br />Earth moving equipment has been used in the past at <br />several locations, This has disturbed the gravels and <br />cobbles armoring the bottom and sides of the channel <br />allowing materials to be moved dO."C1stream. These deposition <br />areas also affect the stream where.er they occur, <br />Streambank erosion also contributes to the loss of riparian <br />habitat and vegetation as well as fo,,'mable land, <br /> <br />The new deposition areas are ~ithout vegetation, Older <br />deposition areas are becoming slowly vegetated, Several <br />landowners along the river have applied Dr. Donald R. <br />Reichmuth's rock drop practices to control the rivers <br />direction of flow. These rock drop practices are being used <br />to keep the water turned away from eroding banks and have so <br />far been effective at relatively low spring runoff flows. <br /> <br />There st ill is the need, a I on9 the streambanks, to <br />cont"o I or stab i I i ze the erOS i on and reduce the damages that <br />have not been corrected as wel I as to protect the farmable <br />lands, irrigation structures, bridges~ riparian areas, and <br />farmsteads. <br /> <br />3 <br />
