>Byron,
>Troy & Jason were at the Edna Mine yesterday. They accomplished the
>following tasks:
>1. looked for middle drain outlet,
>2. surveyed WR-pond slope for new topography and seep locations, 3.
>installed two small surface drains 4. marked P&A'd wells, 5. looked for
>existing wells that still need to be P&A'd, and 6, took pertinent
>photos.
>The middle drain is NOT under a slide and they found no evidence of a
>slide. The attached photos show the middle drain as it was yesterday.
>We are entering the survey data in the design drawing that we used for
>the previous drain design. We had previously collected survey points
>of the extent of wetness (in the late summer 2006). We collected more
>extent of wetness survey points yesterday. We will then be able to
>compare them to see if the are is drying out. We think that the drains
>are working and drying the area out. It may take a bit longer to dry
>out that clay.
>There is one clear spring, that flow water from the ground (photo
>"WRPondSeepTempDrainl 5"). There is also a saturated area that looks
>as if animal foot prints are being filled with water, but have no clear
>sign of groundwater flowing up to the surface
>("WRPondSeepTempDrain 5"). We installed two surface drains down to
>about 1.5 ft-bgs. We buried them for several feet down hill. They
>were not flowing water by the time Troy & Jason le £t the area.
>NOte: it was raining while Troy and Jason were on site, which darkened
>the entire ground surface. The saturated area is easy to determine
>because of the mud created by the depth of water. The rain-wetted area
>was just wet on the surface, without mud.
>The vegetation looks much better (photos "WRPondStoN 1" and
>"WRPondSeepTempDrain 6" We asked Mike Miller to go hand broadcast
>seed with a heavy application when he does the erosion repairs this
>year. He expected to be out there this week or next week.
>The P&A's wells were marked. Their photos are attached for your records.
>Three of the non-P&A'd wells were located. Their photos are attached
>for your records.
>I will suggest to Steve that we go out to the site in August 2007. Our
>objective would be to: 1. survey the seeps and wet areas at the WR
>POnd, and 2. spend a couple of days searching £or the remaining wells
>that need to be P&A's and taking hand-gps shots on them. We can then
>determine if there is a need for further work at the WR Pond and plan
