FRESNO COUNTY, Calif. (KSEE/KGPE) — Officials from the Fresno County Sheriff’s Office have identified the two men who died Sunday in Avocado Lake.

Silverio Calihua, 25, and Alvaro Calihua, 23, both of Fresno, drowned Sunday in the Fresno County lake, according to Sheriff’s Office officials, who add that the two were brothers.

Shortly before 3:00 p.m., on Sunday, Fresno County Sheriff’s Office received reports that both men had gone underwater in Avocado Lake and had not surfaced. Visitors at the lake located Silverio and performed CPR on him. When first-responders arrived 10 minutes later, they took over the efforts. Silverio was taken to an area hospital where he died.

Hours later members of the Fresno County Sheriff’s Office Dive Team recovered the body of Alvaro.

It is unknown what led to the drowning of Silverio and Alvaro, however, officials from the Fresno County Sheriff’s Office have provided safety tips for pools and natural waterways.

  1. Wear a life jacket. Make sure children have one that fits them properly.
  2. Stay out of the water if you are not an experienced swimmer.
  3. Parents should watch their children at all times.
  4. Do not mix alcohol and swimming. Alcohol causes swimmers to fatigue faster than normal and can create dangerous situations.
  5. Understand that when it’s hot outside you will get tired faster than usual.
  6. Respect the water. The temperature of the water remains cold and the current is often stronger than it appears. There can be debris in the water, which is difficult to see and may cause hazardous situations for swimmers. Be careful of the mud on the bottom of lakes and rivers, it’s easy to sink in some spots and get your feet stuck.
