Responses to Division Concerns <br /> Page 6 <br /> They are 1) water monitoring and identification and 2) <br /> bulkhead performance. <br /> 1) Water Monitoring and Identification <br /> As suggested by the Division, SGC has implemented during <br /> 1993, a survey of seeps, springs and flowing adits to <br /> provide baseline water data for comparison against post- <br /> bulkhead conditions, if needed. The basic concepts <br /> employed which were discussed during your site visit to <br /> inspect the drainages are outlined below. <br /> The areas inventoried include: <br /> o the east side of Cement Creek and its <br /> north , middle and south forks along with Minnehaha <br /> Creek. <br /> o the west side of Eureka Gulch including the South <br /> Fork of the Animas River and McCarty Basin. <br /> o the east side of Eureka Gulch from Parson Gulch into <br /> Sunnyside Basin. <br /> o Placer Gulch. <br /> o California Gulch. <br /> o Poughkeepsie Gulch. <br /> These areas were inventoried between elevations of 10, 500 <br /> feet or the bounding stream bed and 12 , 200 feet (the <br /> maximum limit for the mine pool ) for evidence of seeps , <br /> springs and flowing adits. Because of the heavy snow <br /> accumulation during the 92-93 winter, snowmelt conditions <br /> extended well into August making it difficult to <br /> differentiate between ground-water flow and flows fed by <br /> snowmelt. Differentiation was made by use of a <br /> conductivity meter and up-gradient inspection. <br /> At each site field measurements (PH, conductivity and <br /> temperature) were taken. Flows were measured using a <br /> portable flume, a pygmy meter or a beaker and stopwatch <br /> if flows were too small for the preceding flow measuring <br /> instruments. Samples were taken to be analyzed for basic <br /> water chemistry, metals and bromide (to provide <br /> background levels for the tracer study, explained later ) . <br /> Each sample site was located on a topography map (USGS <br /> 15' Quadrangle) for the inventoried area and aerial <br /> photographs for those areas that photographs were <br /> available from SGC files. Study area boundaries were <br /> also placed on the topo maps and photographs. <br />
