The Ocker property,topographically, will drain to the Drainage Ditch.No berms or other earth <br /> structures exist to block the flow path. The topsoil berm on the Lyster Pit is west of the Drainage <br /> Ditch; it does not interfere with flows coming from the Ocker property.No other elevations of <br /> grade above pre-mine topography exists near the Lyster-Ocker property line. Map 1 —NW <br /> Corner shows drainage directions along the property line. Topography is flat enough in the area <br /> of concern that surface water flows can reach the groundwater lake easily. <br /> The Drainage Ditch is thick with vegetation to the point that surface water flows into and <br /> through said ditch would be significantly affected. Connell Resources noted that they mowed <br /> that area when they operated the pit prior 2017. It is likely that this mowing helped with smooth <br /> water flows off the Ocker property given the gentle slope from the east to the west. <br /> There is no slurry wall or clay liner that would impede groundwater flows to the exposed lake <br /> and there is no surface barrier like a berm between the Ocker property and the lake. Any surface <br /> water or ground water flows that pass through the Lyster Pit from the east,that do not get <br /> intercepted by the Drainage Ditch, can drain to the lake. <br /> 4. Conclusion <br /> The groundwater table at the Lyster Pit and Ocker property is so close to the surface that <br /> infiltration capacity is limited. Surface water flows,whether from precipitation or from <br /> irrigation, will not infiltrate very much. The undisturbed pre-mine topography on the east side of <br /> the Lyster Pit is very flat, with less than a 0.2%slope from south to north and roughly 0.5%from <br /> east to west with a low area roughly 150 feet from the northern road ditch. Runoff from east of <br /> the Lyster Pit drains into the Drainage Ditch which then drains to this low, flat area. Given the <br /> lack of infiltration, the runoff in this low point has nowhere to go and sits within the low point <br /> until it evaporates. This leads to standing water in the low point and its surrounding areas. <br /> Depending on the amount of surface water runoff from storm events and flood irrigation,the <br /> extent of the standing water may extend out into the Ocker property from this area in addition to <br /> extending south. This is the natural condition of the area; no mining activities at the Lyster Pit <br /> have altered these conditions. <br /> Lyster Pit NOV <br /> November 2020 7 t:r'iX I awicki and Associnttw Wi,l,t' <br />
