It’s been a big rain year for San Diego County, and that got a Midday Edition listener wondering about the impact on the county’s reservoirs. The listener wrote in with this question: Is SD (County) doing as much as can be done to keep the varying rain amounts in, direct the rain to reservoirs? Purpose of our reservoirs? Are any reservoirs used as sources for drinking water (to be purified)? Recreation, boating & fishing, I’m guessing are the main uses. To answer those questions, Midday Edition spoke to Dana Friehauf, resource manager with the San Diego County Water Authority and Jeff Pasek, watershed manager, city of San Diego Public Utilities Department.
