• Additionallnformation <br />The following excerpt taken from an October 8, 1981 letter from Colowyo to the Division <br />expands further on the colluvium in the Taylor Creek drainage. <br />"In the original permit application submittal, Colowyo had described the soils in the <br />Taylor Creek Drainage (see Map 19, Regional Hydrology) as Quaternary Alluvium. <br />The description was derived from a U. S. Department of Agriculture Service Soils <br />Classification Survey at the series level which identified the Taylor Drainage soil as <br />a (stratified alluvium)." <br />"On the basis of a September 18, 1981 field reconnaissance by Colowyo personnel <br />together with Dave Craig and Brian Munson of the CMLRD staff, it was agreed <br />that the SCS classification of Taylor Creek as an area of stratified alluvium was and <br />is erroneous particularly as geomorphic criteria required to describe an AVF are <br />absent. As a consequence, the designation of the Taylor Creek Drainage as <br />quaternary alluvium on Map 10, Regional Hydrology has been deleted. This area <br />should be mapped as colluvium. <br />"Other examination of the area on September 18, 1981 further confirmed a colluvial <br />classification, in that some unsuccessful irrigation in the area is presumed to have <br />occurred, and such irrigation was practiced on the colluvial slopes adjacent [o the <br />bottom of the drainage. No irrigation ditches, however, are extant, and it is apparent <br />that no subirrigation occurs in the area". <br />• "Additionally, insufficient water flows in the Taylor drainage to sustain any flood <br />irrigation. Irrigation apparently began from a ditch known as the Mary C. ditch in <br />1913 on an undetermined acreage, but was certainly less than 25 acres. The state <br />Division of Water Resources records date back to 1960, and they have no record <br />that this ditch has been used since that time. Years ago small isolated areas such as <br />this could be irrigated economically, and were important to 160 acre size <br />homesteads". <br />L <br />2.06-14 <br />
