The stream data has been gathered by <br />Colony or in many instances by independent consultants (Meiman, <br />1973 b; Wilber; 1973) and contractors (Jex-Morgan, Engineers; <br />Metcalf and Eddy, Inc.). All laboratory analysis has been con- <br />ducted by independent contractors (Grand Junction Laboratories; <br />Industrial Testing Company), and independent consultants have <br />• been fictive in ccitiqueing and formulating the water monitoring <br />program (Skogerboe, 1973; Wilbur, 1973). <br />DESCRIPTION OF WATERSHEDS <br />The proposed"Colony mine and plant complex are situated within <br />the Upper Parachute Creek drainage basin which is part of the <br />Grand division of the Upper Colorado River Basin. Parachute <br />Creek drains an area of about 200 square miles and discharges <br />into the north bank of the Colorado River. The Colony property <br />includes portions of .the three upper tributaries: Davis Gulch <br />(draining 6.4 square miles). Middle Fork (5.6 square miles), <br />and East Middle Fork (34.7 square miles). Two major tributaries <br />(West Fork and East Fork) drain into Parachute Creek south <br />of the Colony property (Figure G-1). <br />in addition, there are a number of springs and gulches along <br />Parachute Creek's course which run intermittently.
