City of San Marcos to launch water quality improvement pilot program at Discovery Lake

The program is designed to keep Discovery Lake clean and beautiful

The City of San Marcos is implementing a pilot program to improve water quality at Discovery Lake as part of the City’s ongoing commitment to sustainability and the preservation of San Marcos’ natural resources.

Two solar-powered ozone injection aeration units will be installed at Discovery Lake starting the first week of February. The aeration units are designed to increase water circulation and inhibit algae growth. The technology was chosen based on the results of a feasibility study that the City conducted last year.

“Our goal for the program is to protect the environment and keep Discovery Lake clean and beautiful for San Marcos residents and visitors to enjoy,” said City of San Marcos Stormwater Program Manager Reed Thornberry.

Visitors to Discovery Lake may notice the installation of small aeration devices, hoses, buoys and informational signs starting Monday, Feb. 3.

The program will be tested for several months to ensure its effectiveness. The City will then evaluate options to potentially expand the program.

The initiative is part of the City’s Stormwater Management Program, which protects the City’s surface waters and maintains their beneficial uses. For more information, visit www.san- marcos.net/stormwater.

Solar powered ozone injection aeration units will be installed at Discovery Lake in the areas marked “Unit #1” and “Unit #2” in the image above starting in February.

Mountain Lion sighting in Lake San Marcos

Our neighbors in Lake San Marcos have shared news that there has been a recent Mountain Lion sighting in their community. This is a reminder that we share our surroundings with various wildlife species and we need to consider this as we spend time in the open space areas and trails that surround our homes.

The following safety tips are provided by the California Department of Fish and Game. They are based on studies of mountain behavior and analysis of attacks by mountain lions.

  • Don’t hike alone. Go in groups, with adults supervising children an keep children close to you. Observations of captured mountain lions reveal that the animals seem especially drawn to children. Keep children within your sight at all times.
  • Don’t approach a lion. Most mountain lions will try to avoid a confrontation. Give them a way to escape.
  • Don’t run from a lion. Running stimulates a mountain lion’s instinct to chase. Instead, stand and face the animal. Make eye contact. If you have small children with you, pick them up if possible so that they don’t panic and run. Although it may be awkward, pick them up without bending over or turning away from the lion.
  • Don’t crouch or bend over. A squatting or bending person looks a lot like a four-legged prey animal.
  • Do all you can to appear larger. Raise your arms. Open your jacket if you are wearing one. Throw stones, branches or whatever you can reach without crouching or turning your back. Wave your arms slowly and speak firmly in a loud voice.
  • Fight back if attacked. Some hikers have fought back successfully with sticks, caps, jackets, garden tools and their bare hands. Since a mountain lion usually tries to bite the head or neck, try to remain standing and face the attacking animal. For more information about mountain lions, contact the Department of Fish and Game (DFG), case of emergency call 911 and DFG at 916-445-0045
