4. SAFETY AND ACCESS FOR MAINTENANCE <br />The landowner of Pond 008 is the Burbridge family, who have farmed the land for many decades <br />prior to mining. They still live in the house immediately south of Pond 008. They intend to allow <br />cattle grazing on the irrigated pasture. As is seen from the plan view of the pond in Map 2.05.3(3)- <br />4-3, the slopes around the pond are mild and typically average 4ti:1 V, which is very easy for <br />anyone to negotiate to clean out the pond and conduct maintenance. <br />No fencing on the Burbridge property is contemplated at this time because it is not needed. <br />5. POND SIZE <br />As described earlier, it is normal for the pond to contain at least 2.0 feet of water depth for at least <br />45 days more than Calamity Draw to the south. At this depth, the pond will contain a volume of <br />0.69 acre feet. The principal spillway is an 18" CMP pipe with an 8' riser on it at elevation 5659.1' <br />• and two 6" sections at elevation 5652.0' which have two 6" valves to regulate the elevation in the <br />pond. This detail is shown on Map 2.05.3(3)-4-3. This is adequate for its intended use. <br />The table below has been extracted from the SEDCAD run in Attachment 2.05.3{3)-4, showing <br />various volumes, depths and <br /> <br />surface acreages for each. <br />rre~anoo ~* <br />ix) taverns <br />(~+U ~~x °ii ~ <br />(~) (hs) <br />s,6a7.oo o.x11 aooo aooo roo orsea. smre9e <br />s,64~so axel 0.1x3 a.ooo <br />s,64aoo o.36x o.xe3 aooo <br />5,64&50 0.40.3 0.474 0.000 <br />s,s49.oo 0.4+6 0.696 o.aoo <br />5,649.50 Q473 0.916 0.000 <br />s,ew.0o asa0 1.15'9 0.000 <br />s,6sow osx6 1.4x6 ao0o <br />s,6sl.oo oss3 L665 aoo0 <br />s,6s1.s0 o,s79 1.969 0.000 <br />s,6sxao 0.60.6 zzrs 0.000 <br />s,6sx.so 0.634 x.s7s o.00o tow nob svw n <br />s,6se.o0 0.661 z.e9e aooo <br />Revised August 2006 Attachment 2.05.33)-19-8 <br />
