The Arizona Game and Fish Department has begun dropping fake plants and other habitat into Roosevelt Lake. Widely varying lake levels at Roosevelt pose problems for natural vegetation.
The work is part of a larger plan, the Tonto National Forest Lakes Habitat Improvement Project, which seeks to help bass and crappie bounce back and boost the sustainability — and fishing prospects — of Salt River reservoirs and Bartlett Lake.
A population explosion of golden algae, a fast-growing invasive plant, has killed thousands of threadfin shad and some gizzard shad at Apache Lake, a reservoir in central Arizona.

The risk of a severe, multi-decade drought hitting the Southwest United States by the end of the century could reach as high as 99 percent if greenhouse gas emissions continue along current lines, says a paper by a team of scientists from Cornell University, Columbia University and NASA.

Human-induced climate change has doubled forest fire damage in the West over the past 30 years, says a study published online early by the journal PNAS. But human effects on fire extend far beyond climate.
Using a technique called satellite radar interferometry, researchers have spotted millimeter-scale ground uplift surrounding four high-pressure injection wells near the eastern Texas city of Timpson. Two of the wells were located directly above a spate of record quakes that struck Timpson in 2012, topping out with a 4.8 magnitude quake on May 17. The other two were located within six miles of the quakes.
