Las Vegas’s new strategy for tackling drought – banning ‘useless grass’

Quote
The ban targets what the Southern Nevada Water Authority calls “non-functional turf”. It applies to grass that virtually no one uses at office parks, street medians and the entrances to housing developments. It excludes single-family homes, parks and golf courses.

2021 is shaping up to be worse than 2015 and much, much worse than 2020.

This is bad (17 years of drought severity maps and other charts)...

Already, twice as many acres have burned in California as during the same period last year. The state’s fire season has expanded in recent decades, starting earlier and ending later than it used to. “Not everything is predictable,” said Dr. Swain of U.C.L.A., referring to events like the dry lightning strikes that ignited many major fires in 2020. “But of the predictable elements — how dry is the soil? And will it get better in the next months? — those are as bad as it can be.

I don't have any data to back this up but based on what I am seeing they are really trying to keep as much water dammed up in the lakes and reservoirs as they can so there is irrigation water in the Columbia Basin this summer. One big lake up in Idaho we visited last weekend had the water level up 6-8 feet vs what it was about a month ago.

>>truck salmon to ocean

Wow. Speechless.

>>earth-heat-imbalance-warming

Again... speechless.

>> water level up 6-8 feet vs what it was about a month ago.

That sounds right. At least in CA reservoirs should peak in July normally (though it appears not this year). Essentially, most of the runoff is May-June and the biggest irrigation needs are June-September, so that ideally yields a high point in July.
