JB Hamby is a water policy bigwig, especially around these parts. He helps shape policies that define how water is used by arguably the most influential water users along the Colorado River. Hamby holds two jobs – he serves on the board of directors for the Imperial Irrigation District (IID) and was recently appointed to be California’s top water negotiator. And he’s only 27 years old. The Colorado River is governed by more than a century of legal agreements, most of which were hammered out by generations of older white men. The ranks of the river’s top policy negotiators have begun to diversify in recent years, including more women and people of color, but still tend to skew older. Hamby’s inclusion marks the first time a member of Generation Z will be at the negotiating table, making deals for the Southwest’s most important water source.
