AQUAFORNIA KICKOFF-Like Texas, Calif. Faces Serious Flood Risks; New Ariz. Law Raises Groundwater Concerns

In today’s Aquafornia scroll:

  • Like Texas, California faces major dangers when extreme floods come, Los Angeles Times
  • Groundwater replenishment left hanging by new Arizona law, Arizona Daily Star (Tucson)
  • Concept for Colorado River agreement emerges in states’ negotiations, The Denver Post (Colo.)
  • White House details proposed NOAA research, science cuts, E&E News by Politico

Water Word of the Week: With summer here and outdoor water temperature heating up across California, algal blooms are starting to surface at lakes, including at Lake Powell along the Colorado River. Algal blooms are sudden outbreaks of algae. While only a few types of algae can produce toxins, even nontoxic blooms hurt the environment and local economies by diminishing water quality, harming marine life and impacting tourism. When masses of algae die and decay, they can deplete oxygen in the water to the point of causing devastating fish kills. So, we’re making algal blooms our Water Word of the Week. You can learn more about this and other water-related topics in Aquapedia, our online water encyclopedia. 

What’s on Tap: The California Natural Resources Agency will host a public listening session on the draft Tribal Stewardship Policy and Toolkit on July 8. See details on this and other upcoming water meetings on our events calendar.

At the Foundation: Our Water Summit, the Water Education Foundation’s premier annual event, returns Oct. 1 at The Sawyer Hotel in downtown Sacramento with leading policymakers and experts addressing critical water issues in California and across the West. Watch for an announcement soon with the summit’s theme! Now in its 41ˢᵗ year, the Water Summit is an ideal event for water district managers and board members, state and federal agency officials, city and county government leaders, farmers, environmentalists, attorneys, consultants, engineers, business executives and public interest groups. Click here to sign up for our announcements to learn more about the Summit and its theme!

Water Resource of the Week: Our Sacramento-San Joaquin Delta Map highlights the region and its importance as an agricultural stronghold, ecological resource and linchpin of California’s water supply system. The text, photos and graphics explain issues related to land subsidence, levees and flooding, urbanization, farming, and fish and wildlife protection. An inset map illustrates the tidal action that influences the salinity of the Delta’s waterways. Order your copy by emailing MLapkass@watereducation.org.

Western Water, our flagship publication by Foundation journalists, is available online. Check out our latest article: 

  • California’s Quest to Turn a Winter Menace Into a Water Supply Bonus is Gaining Favor Across the West
