CHAPTER IX INSTRUMENTATION AND MONITORING

instrumentation and monitoring programs requires staff to apply engineering judgement and common sense. A major change in the extent of existing instrumentation programs at most projects is not anticipated, though some dams will require additional instrumentation. Many monitoring programs may need to be improved.
