As the NFHS Officials Manual consistently reminds us, common sense and judgment are key factors in consistently following, and applying both the letter, and intent of NFHS rules successfully. Expecting any set of rules to explicitly relate to EVERY possible situation is unreasonable, and impractical and would be impossible to keep updated, or practical to keep track of.
If the "puddle" in your example stretched from sideline to sideline and was so wide, or deep, to make adjustment impractical, a judgment, by the referee, who would be guided by NFHS 1-1-6 providing that the referee's decision, alone, made in the spirit of sportsmanship, would prevail.
1-1-6 relies on the judgment, maturity, impartiality and common sense of the senior game official to render a specific judgment to an equally specific and unique circumstances he is confronted with in that unique situation. Although the ultimate decision is the referee's to make, he is not restricted from seeking advise and counsel from his crewmates and/or any other sources he chooses to consider.
