On a windswept landscape somewhere north of Denver, Robert Hawks, a feisty and dangerously curious hydrologist, finds himself enmeshed in a fight over Native American treaty rights. What begins for Robert as a peaceful fishing interlude ends in murder and the disclosure of government secrets. Everett mines history for this one, focusing on the relationship between Native American activists and Black Panther groups who bonded over their shared enemies in the 1960s Civil Rights movement.

Watershed is an excellent example of Percival Everett's famed bitingly political narrative style.
