The Lago Santa Margarita is located a short distance from the intersection of the Santa Margarita and Antonio Parkways, in the shade of Mount Modjeska and Mount Santiago, Saddleback’s twin peaks, and in the shadow of the Santa Margarita and Antonio Parkways. Water is stored in the Lake, which has a radius of 1.1 miles and an area of 11.5 surface acres. The Lake’s capacity is 31 million gallons.

It was named after the Spanish and Rancho traditions of the region, and it was erected in 1985 after being designed by J. Harlan Glenn and Associates and constructed by the same company in 1985. The Spanish word lago literally translates as “lake,” and Santa Margarita was the name of a property that was purchased by Irish cattleman Richard O’Neill in the early 1900s.

The Lake is one foot deep at the outside and progressively slopes toward the center in a five-to-one ratio: for every five feet traveled towards the center, the Lake becomes one foot deeper, with a maximum depth of eight feet. The Lake has a maximum depth of eight feet. During the course of the year, the temperature of the Lago Santa Margarita changes naturally, ranging from a pleasant 80 degrees in the summer to a frigid 50 degrees in the winter.

Seasonal events in Lago Santa Margarita include the Star-Spangled Spectacular, held in commemoration of the Fourth of July, and the Annual Christmas Tree Lighting, which takes place in December.

In addition, the Lake is an excellent location for a range of leisure activities throughout the year. Residents of the neighborhood enjoy taking the 1.1-mile stroll around Lago Santa Margarita, which is a popular spot for exercise. Despite the fact that swimming in man-made recreational lakes where the water is not recirculated is against California law, Lago Santa Margarita is a popular destination for remote-controlled boats and recreational fishing.

The Lago Santa Margarita in Rancho Santa Margarita is owned by the Rancho Santa Margarita Landscape and Corporation (SAMLARC). All year, the SAMLARC Board of Directors oversees the management of this priceless asset, which is used for the benefit of the whole SAMLARC community as well as the personal delight of the SAMLARC residents and their guests.

Constant work is required to keep the water level consistent and the aquatic ecosystem as pure as possible. The lake surface is skimmed for leaves and other floating garbage at least three days a week, and the Lake is inspected on a daily basis. In order to control the spread of algae and weeds in the Lake, it is treated as necessary with methods that are not harmful to the valuable flora as well as the fish, turtles, ducks, and other creatures that make their homes in the Lake.
