There is something lurking in the water of Lake Jennings. It’s not a sea monster, but rather a tiny submarine that is part of a study testing the lake’s water quality. On October 30th, a harmless dye called rota-meen was put into Lake Jennings by Scripps to track the mixing of purified water with the water of the lake. Now more than ever, San Diego needs a study supply of water. They will collect the data with a submersible drone. Using advanced purified water could mean less water would need to be imported from the Colorado River.

Most Americans may not realize it, but we really don’t know with a lot of accuracy how much snow there is sitting in the mountains during winter. We also don’t always have a precise picture of where the snow level is when a storm moves in, or how much will run off when the snow melts. One reason for this is that, in most areas, the weather sensor network in the mountains simply isn’t very dense. Gauges that measure rain and snow are often placed for convenient access.
Wildfires burned millions of acres of land across the western United States over the past several months, leaving many areas at risk of flooding and mudslides during winter. As of Nov. 6, wildfires have burned over 8.8 million acres across the United States, more than 2 million acres above normal, according to the National Interagency Fire Center. Some of the most devastating fires scorched Northern California in early October, leaving behind large burn scars, or areas of scorched earth with little vegetation remaining.
California WaterFix is at an impasse, or so it seems. In a perfect world, the project’s gaping hole in funding from State Water Project contractors, embarrassing outcomes from state and federal audits, and vehement opposition from the general public and environmental groups would have killed the tunnels. But the real world functions on compromise and profit. This view is echoed by those, including Jay Lund of UC Davis’s Center for Watershed Sciences, who say there is “no perfect solution” to California’s water crisis and suggest that tunnel opponents consider a single tunnel in the Delta.
California’s Water Resources Control Board described its new Salton Sea plan as a landmark agreement, but at least one expert is questioning the modified approach, calling it “Band-Aids to a very serious environmental disaster.” With water deliveries from the Colorado River coming to a halt at the end of this year, the shrinking lake will be reduced at an even faster rate, which the state says poses a public health risk due to particulate air pollution by dust blown from the exposed lake bed.
Did you know just one inch of rain yields 650 gallons per every 1,000 square feet of roof space? Solana Center, in partnership with the San Diego County Water Authority, has brought back the discounted rain barrel program for San Diego County residents. Not only do rain barrels conserve precious water, they help protect our watershed and oceans by reducing urban water runoff, which is a major source of ocean pollution. The 50-gallon rain barrels are made of 100 percent recycled material and come with all the parts to start catching water now.
The California State Water Resources Control Board (State Water Board) adopted the final draft stipulated order on Tuesday that includes conditions benefiting the Salton Sea restoration. The Board’s action revised State Water Board Order WRO 2002-0013, which was approved in 2002 authorizing the largest agricultural to urban water transfer in the United States.
