This, as intended, had the <br /> desired effect of reducing the sediment in the 1993 spring snowmelt runoff. <br /> Measures were taken over the course of the summer and fall to minimize, to the extent <br /> possible, erosion and sediment loss from the roads. These include: <br /> All Roads: <br /> Checked culvert outlets and road ditch outlets to determine whether additional <br /> ripran rneferi�1I rPrY!Ilrpr! ar�lri lr� rer� r, rn7lear1. •..h••. . �J.....I %J <br /> e- o-• -• .;p. . 2 .e e.navi.23� irl eve v dGa f ad necessary of <br /> desirabie. <br /> Road A: <br /> Cleaned culvert inlets AA A-2, A-3, A-4, A-5, <br /> Cleaned all of road ditch A. <br /> Road B: <br /> Cleaned culvert inlets B-2, B-4. <br /> Cleaned all of road Ditch B. <br />
