Section 785.19 (c) Continued. <br />r~ <br />L <br />• <br />The fifth subject area is Williams Draw. It is located on photo- <br />graph 359 parallel and to the left of Bush Draw. Red reflectance <br />is visible along the entire length of the draw but is restricted to <br />the narrow streambed, except for about a two acre area associated <br />with a retention dam located approximately two inches from the <br />Canadian River (on the photograph). On the upstream aide of the <br />dam there is a red area of herbaceous vegetation located in the <br />bottom of the channel. The redness indicates that sufficient <br />moisture is present to sustain green living plants. The reddish- <br />yellow areas adjacent to the dark red area indicates that few green <br />plants are present outside the stream channel. White areas adja- <br />cent to the drainage channel are areas with sparse plant cover and <br />bare ground interspaces. The plants appear as bluish blotches when <br />viewed with 8x magnification. Whitish areas on the ridges and <br />upland areas bordering the draw have a gravel or exposed shale <br />interspace with little plant cover. The lack of green plant cover <br />along the floodplain demonstrates the absence of sub-irrigation. <br />There is no evidence of a flood irrigation system associated with <br />Williams Draw. <br />The sixth subject area is Sudduth Draw located to the north of <br />Williams Draw on photograph 359. There are intermittent areas <br />displaying red reflectance in Sudduth Draw. These are associated <br />with retention dams. Three inches from the bottom of the photo- <br />graph is the first and largest of four ponds that can be seen in <br />the draw. The channel upstream from this pond has no red reflec- <br />tance indicating that it is either denuded of plants or that the <br />plant material is dry and of a yellow color. One inch down stream <br />is the second pond which is seen as a powder blue color. The third <br />pond is 3/4 of an inch below the second and can be seen with a 2x <br />stereoscope. Red reflectance can be observed from below the first <br />pond to 3/8th of an inch below the third pond. Because of the <br />785-26 <br />
