AND LEGEND

1. CONSTRUCTION IS SUBJECT TO THE BUREAU OF INDIAN AFFAIRS (BIA) SAFETY OF DAMS PROGRAM HANDBOOK. SUBSTANTIVE CHANGES TO THE APPROVED DRAWINGS AND SPECIFICATIONS REQUIRE APPROVAL OF THE CONTRACTING OFFICER OR CONTRACTING OFFICERS REPRESENTATIVE.

2. LOCATION AND NATURE OF EXISTING UTILITIES SHOWN ON THE DRAWINGS ARE APPROXIMATE. FIELD LOCATE ALL UTILITIES, WHETHER SHOWN ON THE DRAWINGS OR NOT, PRIOR TO EXCAVATION. PROTECT ALL UTILITIES IN PLACE UNLESS DESIGNATED FOR REMOVAL OR REPLACEMENT.

3. UNLESS SHOWN OR SPECIFIED OTHERWISE, PAYLINES FOR UNIT PRICE PAY ITEMS ARE BASED ON THE DESIGN LINES (NEAT LINES) SHOWN ON THE DRAWINGS.

4. CONTRACTOR IS RESPONSIBLE FOR DESIGN, IMPLEMENTATION, OPERATION AND MAINTENANCE OF ALL SEDIMENT AND EROSION CONTROL MEASURES DURING CONSTRUCTION.

NOTES:

1. BORING LOGS SHOW GENERALIZED SUBSURFACE CONDITIONS AND ARE NOT INTENDED TO BE A COMPLETE OR ACCURATE DEPICTION OF THE SUBSURFACE CONDITIONS. COMPLETE BORING LOGS AND SURFACE INFORMATION IS PROVIDED IN THE

GEOTECHNICAL DATA REPORT.

2. SUBSURFACE STRATIGRAPHY IS KNOWN ONLY AT THE BORING LOCATIONS AND AT INTERVALS SAMPLED AND MAY DIFFER AT OTHER LOCATIONS. INTERPRETATIONS OF SUBSURFACE STRATIGRAPHY BETWEEN SAMPLES PRESENTED ON THE SUMMARY

LOGS ARE BASED ON REASONABLE ENGINEERING INTERPRETATIONS OF THE DRILLING DATA.

3. THE NEW DAM CENTERLINE IS OFFSET FROM THE EXISTING DAM CENTERLINE. THE APPROXIMATE EXISTING DAM CREST IS

SHOWN FOR REFERENCE ONLY.

4. GROUNDWATER WAS NOT ENCOUNTERED DURING DRILLING, AND IT IS ESTIMATED THAT THE RESERVOIR WATER SURFACE

ELEVATION WAS BETWEEN ABOUT 1739.5 AND 1740.0 DURING DRILLING.

NOTES:

1. CORE TRENCH EXTENDS INTO COMPETENT BEDROCK.

2. BASE OF EARTHFILL CORE SHALL BE PLACED A MINIMUM OF 6 INCHES INTO COMPETENT BEDROCK.

3. CONTROL POINTS EX-101 THROUGH EX-106 PRESENT APPROX ELEVATION OF BOTTOM OF EARTHFILL CORE ALONG

THE DAM CENTERLINE. CONTROL POINTS EX-107 THROUGH EX-113 PRESENT THE ESTIMATED LIMITS OF THE BOTTOM OF THE EARTHFILL CORE. THE LAYOUT AND ELEVATION OF THESE CONTROL POINTS ARE BASED ON RESULTS OF THE SUBSURFACE INVESTIGATION. ACTUAL EXCAVATION LIMITS WILL VARY BASED ON FIELD CONDITIONS.

4. EXCAVATE APPROX HORIZONTAL TO FACILITATE OUTLET WORKS CONSTRUCTION.

5. CLEAR 5 FOOT WIDE WALKING PATH TO ACCESS BRIDGE. MAXIMUM LONGITUDINAL SLOPE IS 20 PERCENT AND

MAXIMUM CROSS SLOPE IS 4 PERCENT.

6. EXCAVATION INCLUDES 2.0' OF HORIZONTAL EXCAVATION OUTSIDE LIMITS OF STRUCTURE FOUNDATION.
