Remember when Trump had officials open the dams, "the giant faucet" to send more water downstream so that California would get more water, but the water actually went down the Columbia River and into the Pacific because it does not connect to Cali? This clip is in relation to that. The U.S. and Canada have a treaty regarding the Columbia, which flows down from Canada, relating to the amount of flow allowed, flood control, hydroelectric power, etc. The treaty is up for renewal. Biden had basically negotiated an extension but it has not yet been approved, so now that agreement will be subject to Trump's heralded negotiating skills.
If he negotiates with his usual combination of tactlessness combined with extortion, Canada could cut the flow tremendously. They could open the dams and send a lot downstream all at once. Who knows? In any case, this is likely of interest to any of our Pacific Northwest members.
