South Chain of Lakes Study

Starting on April 30, 2018, Zone 7 and the quarry operator, CEMEX, are collaborating on a groundwater study near the intersection of Isabel and Vineyard Avenues at Lakes A and B of the future Chain of Lakes facility. The study will include drilling into the ground near the lakes to collect data on aquifer conditions and soil characteristics. Drilling activities are not expected to impact traffic or trail access, as the drill rig will be within the perimeter of the mining area. The study is expected to last about a month.

Zone 7 Celebrates its 60th Anniversary

To commemorate our 60th anniversary, while also promoting water awareness, Zone 7 Water Agency has created this 18-month (July 2017 - December 2018) calendar. Zone 7 Water Agency, in partnership with local water retailers, invited 4th-grade students within our service area to share their artistic talents by creating a poster that illustrates the importance of water conservation, flood protection, and watershed management. Winners of the poster contest are featured in the calendar. An electronic version of the calendar is now available for download.

Check out our 60th anniversary flyer covering Zone 7's history from 2007 to 2017. Expanding on that, our 60th anniversary booklet covers Zone 7's history from 1957 to 2017.
