a--Walsh <br />Environmental Scientists and Engineers, LLC <br />Jubb Creek Springs <br />Two springs were identified and sampled in the Jubb Creek drainage — SPRJ -01 and <br />SRPJ -02. SPRJ -01 is located at the confluence of two small drainages in the headwaters <br />of East Fork Jubb Creek. The spring emerges from the base of the hillside between the <br />two drainages. The point of emergence is currently identified by a dead tree. The source <br />appears to be a bedrock outcrop. This spring is considered to be perennial. Water flow is <br />captured immediately downstream by a stock pond. Below the stock pond are a windmill <br />and alluvial well MJ- 95 -02. <br />SPRJ -02 is a series of small springs that emerge from the east side of the incised channel <br />of Jubb Creek below the confluence of the east and west Forks of Jubb Creek. The <br />springs emerge from alluvial valley fill in three or four distinct places and numerous <br />smaller seeps were observed over a section of bank approximately 150 feet in length. The <br />three to four distinct springs each had minor flow on December 8, 2004, while the <br />conjoined flow at the sampling point was approximately 0.5 gpm. The source of the <br />springs and seeps at this locale is most likely the extensive alluvial valley fill in the <br />stream banks. Each distinct spring emerges several feet above the stream bed. <br />Collom Gulch Springs <br />Four springs were surveyed and sampled in Collom Gulch — SPRC -01 through SPRC -04. <br />SPRC -01 is a series of distinct springs and seeps that emerge from a cut bank <br />approximately 50 feet in length in Collom Gulch. On December 2, 2004, discharge was <br />estimated at 0.5 gpm from the sampling point. The spring is generally undeveloped; <br />however, a discharge pipe has been placed in the bank at the furthest down gradient <br />spring. Though the spring exits from shallow valley fill, the source is most likely buried <br />bedrock outcrop. This spring is considered to be perennial. <br />SPRC -02 is located on the road cut that climbs east out of Collom Gulch. The spring <br />emerges as numerous small seeps and springs from the rock outcrop exposed by the road <br />cut. On December 2, 2004, discharge was estimated as less than 0.25 gpm. The source of <br />the spring is a bedrock outcrop. <br />SPRC -03 is located on the flat, broad valley bottom below the road that climbs out of <br />Collom Gulch to the west. The spring emerges as a large saturated zone with several <br />areas of standing water. December 2, 2004, discharge was estimated as less than 0.2 gpm. <br />Although the spring exits from an extensive valley fill, the source is most likely a <br />bedrock outcrop across the road to the west and up gradient of the spring. The large <br />saturated area from which the springs emerge eventually forms small braided streams that <br />merge and become incised. The smaller streams continue to merge and eventually <br />discharge into the incised stream channel of Lower Collom Gulch. <br />SPRC -04 is located just south of the synclinal axis on the eastern side of the incised <br />channel near the base of a hill. The spring emerges as a large saturated zone with several <br />areas of standing water. December 2, 2004, discharge was estimated at less than 1 gpm. <br />P PROJPCTS'Colowyo.6188.EA Finat•nLlt -v -EA Coll ,, 6821 o. dot: <br />30 <br />
