Pitch Reclamation Project Colorado Mined Land Reclamation Board — 2016 Annual Reclamation Report <br /> water level in PZ-4 increased by 6.31 ft but fell back rapidly. In 2016, the increase was only 0.36 ft. The <br /> high pressure flushing of PZ-7 and PZ-8 in late 2015 allowed water levels in both piezometers to rise and <br /> fall back quickly compared to their behavior in 2013 and 2014. The piezometers will be inspected for silt <br /> build up in 2017 and pressure flushed as necessary to eliminate silt buildup. <br /> The debris trap above the outlet pipe was cleaned in 2016 and pine seedlings were removed from the <br /> downstream face. The debris trap will continue to be cleaned in 2017. The downstream face of the <br /> embankment will be inspected following the spring melt for potential seepage, remove pine seedlings and <br /> repair rill erosion as need. The monuments will be surveyed again in the summer or early fall of 2017 and <br /> the piezometers will be monitored monthly or more often if it is necessary to store water above the 9885 ft <br /> amsl level. <br /> A Sediment Control Pond Embankment Report is submitted annually to the Colorado Division of Water <br /> Resources providing the results of the embankment-monitoring program. The 2016 report is provided on <br /> the CD attached to this report. <br /> The Sediment Control Pond embankment is shown in Photograph 21. <br /> Photograph 21: Sediment Control Pond Embankment with Blue Heron <br /> 23 <br />
