Our California Water Map, recently updated, is one of our most popular products. We also offer magazines, documentaries, posters, layperson guides and more. Our catalog offers a wide array of resources to help you understand the complex issues of water in California and the Southwest.
California’s groundwater is a great natural resource and has contributed to the state becoming the nation’s top agricultural producer and a leader in high-tech industries. Groundwater is an asset that is increasingly relied upon by municipalities, industry and agriculture and it will play an important role in the future sustainability of California’s overall water supply.
There is a timelessness to the Colorado River as it makes its ancient run from the headwaters in the Upper Basin through the arid Lower Basin states and to the farm fields, wildlife habitat and urban environment that make up the Southwest.
There also is a sense of urgency regarding how an overallocated river is managed for its many competing uses in the face of looming shortages and a grim climate change forecast that predicts much less river flow in the years to come.
Californians are beginning to wonder: Is the state heading back into a drought? While experts say it’s still too early in the winter rainy season to say for sure, the evidence is accumulating, and the rain is definitely not.
The head of the U.S. Environmental Protection Agency pledged that lead regulations will be a prominent feature of the agency’s work in 2018 — but that work will take longer than anticipated. The agency expects that a revision to federal rules that are designed to reduce the risk of lead in drinking water will be published in draft form in August 2018, a seven-month delay from a timetable announced this summer.
After combing through a decade’s worth of Pennsylvania birth records, researchers have found that pregnant women living within two-thirds of a mile of a hydraulic fracturing well were 25% more likely to give birth to a worryingly small infant than were women who lived at least 10 miles outside that zone during pregnancy.
Last winter’s drought-busting wet weather was a boon for reservoirs and parched landscapes, but not so much for some invasive species in San Francisco Bay, according to a long-term study by Tiburon-based researchers. All that fresh water that poured into the bay was bad news for certain invaders, which have turned up in droves in recent decades from around the world, often in ships’ ballast water.
The endangered Delta smelt is a 3-inch fish found only in the Sacramento-San Joaquin Delta. It is considered especially sensitive because it lives just one year, has a limited diet and exists primarily in brackish waters (a mix of river-fed fresh and salty ocean waters that is typically found in coastal estuaries).
