• The very slow flow rate of 0.038 gpm makes the magnitude of this <br />spring an eigth order. Most springs of magnitude eight only flow <br />a short time following periods of precipitation. <br />Although no distinct odor was present, a large quantity of <br />either iron bacteria or ferric hydroxide precipitate gave the <br />water an orangish coloration. Iron stains were also present on <br />the sandstone around the spring. The water was directed into a <br />tank where cattle sometimes water. <br />Starkville Gulch Spring, Section 36 <br />The lower reach of the Starkville Gulch is fed by a spring. <br />It emerges from the Vermejo Formation near the contact with the <br />Trinidad sandstone. Prior to start of construction at the Helen <br />Mine, this spring was only a seep which produced no measurable <br />flow into Starkville Gulch. This seep was situated directly <br />• below the proposed sedimentation pond. During pond excavation, <br />a 4 inch PVC drain pipe was placed in the seep with the drainage <br />end protruding downstream of the dam. The seep was then backfilled <br />with Vermejo clay material, compacted, and will serve as the <br />sedimentation pond for permit area storm runoff. Discharge from <br />this modified spring/seep was measured as 7.2 gpm making this a <br />sixth order spring. <br />Baseline water Quality <br />All of the springs, except those in upper Moores Canyon, <br />appear to originate in the Vermejo Formation. The water quality <br />of the spring shown in Table 5 verifies the distinct differences <br />in chemical composition of the Vermejo and Raton aquifers. As <br />a general indicator, the conductivity of the Vermejo is approx- <br />imately four times that in Raton aquifer water. <br /> <br />FISHER, HARDEN 8 FISHER <br />130 <br />
