The pages go from newest to oldest. There are also notes all over the <br /> place near the measurements as to what was/is happening. If I have been remiss in attaching well measurements <br /> to my annual reports to the DRMS, I am sorry. Please excuse the lack of the data in the last few years' reports. <br /> Please note the following: <br /> 1. The requirement for well measurements at this site was initially and only for dry mining. That had to do with <br /> offsite impacts. These wells (and some got mined thru)were only upgradient from the dry mining. <br /> 2. 1 do not remember why we added well #9 (further north on Brighton Rd.) but that may have been in say -2005 <br /> due to adding on the Seeger property and mining thru two others that were along his old property line that was <br /> then the farthest east of dry mining on the Speer property. Yes, that is why. <br /> 3. Wells #10 and #11 were only drilled on the riverside recently for water sampling for the inert fill permit. <br /> 4. Any recent water level measurements are either only due to the sampling program for CDPHE or due to the <br /> high groundwater issue we "caused" beginning in 2009 due to mounding upgradient of some fill we put in on the <br /> Brighton Rd. side. <br /> 5. 1 came to work for this company in 2001. What I term the "normal"water elevations in wells #3 and #9 are <br /> not really normal at all, it is just what I was used to with all measuring up until we shut the pumps off from dry <br /> mining. Those elevations were artificially depressed due to the dry mining. Normal (pre-dry mining in the entire <br /> area)water elevations are generally what are occurring now. <br /> 6. Please forward this info to Tyler if he is interested. I also have well measurements dating back to -2000, but <br /> many of those wells are gone. Only#3 remains from that "era". <br /> I have gone over and over all this data for what, 5 years? I have piles of it. It just won't go away! I believe Mike R. <br /> has deepened somewhat the trench downside of the culvert for the lake outlet. You might call Levi Kirby say <br /> tomorrow and ask him if his pump is no longer cycling on. It only takes a foot or two of reducing the water table <br /> for everything to be OK. <br />
