City of San Diego crews worked through the night to repair a sinkhole closing a popular route in or out of Pacific Beach just north of Garnet Avenue. A 30-inch transmission water pipeline burst Monday, prompting the closure of the Interstate 5 off-ramp to Mission Bay Drive. The break, reported before noon, created a massive sinkhole estimated at more than 30 feet in diameter on the northbound lanes of Mission Bay Drive at Damon Avenue.

Dudek will be studying the possibility of the Rainbow Municipal Water District obtaining some of its water supply from the Bonsall Groundwater Basin of the San Luis Rey River. The board voted 5-0 to approve a $572,903 contract with Dudek, Oct. 24, to provide engineering services for studies which would bring a Bonsall Groundwater Basin desalter project closer to implementation. “This project is to evaluate what water rights we have in the Bonsall basin and the feasibility of extracting that,” Rainbow general manager Tom Kennedy said.

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.

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 State Water Resources Control Board Tuesday committed to an annual timetable for habitat restoration and dust suppression projects aimed at rehabilitating the Salton Sea over the course of the next decade. The agreement sets milestones for completing projects within the $383 million Salton Sea Management Plan, which calls for construction of 29,800 acres of ponds, wetlands and dust suppression projects to restore the receding lake, beginning with 500 acres in 2018, increasing to 4,200 acres by 2028. The agreement also includes committing to a long-term plan — to be created by 2022 — that goes beyond the initial 10-year plan.
