Silver Lake Water Hardness & Quality Report (2026)

Silver Lake, Los Angeles, California — a major Eastside Los Angeles neighborhood (Silver Lake is one of the most iconic and culturally significant neighborhoods in Los Angeles — a hillside neighborhood northeast of downtown LA, known for its bohemian and arts-oriented character, Silver Lake Reservoir, and as one of the creative epicenters of Los Angeles culture; Silver Lake is frequently cited as one of the first neighborhoods in the Los Angeles hipster gentrification wave, now one of the most expensive residential areas in the city), a diverse Los Angeles County community with a significant Latino-American, LGBTQ+, and creative professional population, adjacent to Echo Park and Los Feliz, home of the Silver Lake Music Conservatory (founded by the Red Hot Chili Peppers' Flea), and one of the most architecturally significant neighborhoods in LA (Richard Neutra and Rudolph Schindler designed many Silver Lake modernist homes) — draws its municipal water supply via the Los Angeles Department of Water and Power. Water hardness in Silver Lake measures 52.5 mg/L — classified as very soft.

Silver Lake's very soft supply reflects the LADWP Eastside distribution zone's Owens Valley aqueduct dominance. The Los Angeles Aqueduct (Owens River — draining calcareous-poor Sierra Nevada granite and Owens Valley volcanic deposits) provides the primary LADWP Eastside supply. The dominant Owens Valley supply produces the very soft 52.5 mg/L.

With hardness at 52.5 mg/L, Silver Lake residents enjoy very soft water. LADWP consistently delivers water meeting all California DDW and EPA Safe Drinking Water Act requirements.
