Picnic Point-North Lynnwood Water Hardness & Quality Report (2026)

Picnic Point-North Lynnwood, Washington receives drinking water through the City of Lynnwood, which is supplied by the City of Everett's municipal water system. The primary source is Spada Lake Reservoir, a major impoundment located in the Cascade Range foothills northeast of Lynnwood in Snohomish County. Water is treated at Everett's treatment facilities before being transmitted to Lynnwood's service area via interconnected transmission mains, from which it is distributed throughout the Picnic Point-North Lynnwood community.

Spada Lake Reservoir is situated within the Snohomish River watershed, draining the western Cascade Range. The underlying geology consists of Quaternary glacial deposits overlying Tertiary volcanic and sedimentary rock formations, shaped by Pleistocene glaciation and volcanic activity. These geological units contribute moderate levels of dissolved minerals to the reservoir supply, with both glacial meltwater and groundwater from the surrounding volcanic terrain influencing water quality — producing moderately hard water typical of western Washington's Puget Sound lowland geology.

Moderately hard water in Picnic Point-North Lynnwood may produce gradual scale buildup on fixtures, water heaters, dishwashers, and washing machines. Periodic maintenance of appliances is advisable, and point-of-use softeners are an option, though whole-home softening is typically unnecessary at this hardness level. According to the City of Lynnwood's 2025 Annual Water Quality Report, the system maintains pH levels generally above 7.4 with occasional brief excursions below that threshold, and nine contaminants were identified as exceeding health guidelines. The water undergoes standard treatment — coagulation, filtration, and disinfection — to meet all Safe Drinking Water Act requirements.
