See page 3. <br />Dam is in satisfactory condition, but unknown condition of old outlet, with its intake buried in silt, has been <br />neglected for many years warrants conditionally satisfactory rating. Also condition of siphon is unknown. <br />Based on this Safety Inspection and recent file review, the overall condition is determined to be: <br />0 (71) SATISFACTORY n (72) CONDITIONALLY SATISFACTORY <br />MAINTENANCE • MINOR REPAIR • MONITORING <br />0 (80) PROVIDE ADDITIONAL RIPRAP: <br />0(81) LUBRICATE AND OPERATE OUTLET GATES THROUGH FULL CYCLE <br />0(82) CLEAR TREES AND /OR BRUSH FROM: <br />(84) GRADE CREST TO A UNIFORM ELEVATION WITH DRAINAGE TO THE UPSTREAM SLOPE: Add more road base to make it easier to maintain <br />r� <br />I0� (85) PROVIDE SURFACE DRAINAGE FOR: <br />0 (86) MONITOR: <br />(87) DEVELOP AND SUBMIT AN EMERGENCY PREPAREDNESS PLAN: Update plan as changes occur <br />(88) OTHER <br />R(89) OTHER <br />ENGINEERING • EMPLOY AN ENGINEER EXPERIENCED IN DESIGN AND CONSTRUCTION OF DAMS T0: (Plans and Specifications must be approved by State Engineer prior to construction.) <br />El (90) PREPARE PLANS AND SPECIFICATIONS FOR REHABILITATION OF THE DAM: <br />0(91) PREPARE AS -BUILT DRAWINGS OF: <br />❑ (92) PERFORM A GEOTECHNICAL INVESTIGATION TO EVALUATE THE STABILITY OF THE DAM: <br />0 (93) PERFORM A HYDROLOGIC STUDY TO DETERMINE REQUIRED SPILLWAY SIZE: <br />0(94) PREPARE PLANS AND SPECIFICATIONS FOR AN ADEQUATE SPILLWAY: <br />0 (95) SET UP A MONITORING SYSTEM INCLUDING WORK SHEETS, REDUCED DATA AND GRAPHED RESULTS: <br />(96) PERFORM AN INTERNAL INSPECTION OF THE OUTLET: Both old pipe & siphon.
