Stage and Rain Gage at Dublin Creek

The California Department of Water Resources has entered into a contract with the Zone 7 Water Agency to install a telemetered precipitation and stage gage system along Dublin Creek as part of the California Stream Gage Improvement Program. The installation includes two pressure transducer probes, a tipping bucket rain gauge, stage gages with staff plates, a tagline and pulley system, a solar panel, and an enclosed housing unit for the electronics, all mounted on two galvanized pipes driven into the ground outside the creek channel. Work is constrained to minimal environmental impact, utilizing only hand tools without removing vegetation or altering the streambed, and is administratively justified under CEQA categorical exemption 15306 for information collection. The system is designed to provide continuous, real-time data on water stage and precipitation levels to state and public monitoring platforms, with all equipment to be operational and unattended at the site. The place of performance is clearly defined as the northwest quadrant of the Highway 580/680 interchange in Dublin, California, at coordinates 37.70217, -121.92461. No formal federal contract clauses, pricing details, payment terms, accounting codes, invoicing instructions, or packaging specifications are documented within the provided materials. The contract lacks specified start or end dates, delivery schedules, FOB terms, or any identified contracting officer, COR, or COTR, with Brian Humphrey of the Department of Water Resources serving as the primary point of contact and likely de facto project representative. The Zone 7 Water Agency is the performing entity, but no UEI, CAGE code, small business status, or socioeconomic certifications are disclosed. The solicitation number is 2025080605, posted on October 17, 2025, with an associated signature date of October 16, 2025, though the exact contract execution date remains unclear. There are no referenced MIL-STD standards, bar-coding requirements, or technical specifications beyond environmental compliance, and no inspection or acceptance criteria beyond adherence to the exemption’s scope. The procurement process and award basis are not detailed, and no attachments, representations from the offeror, or special requirements such as security clearances or options clauses are enumerated, indicating a streamlined, low-risk state-funded environmental monitoring project governed primarily by California regulatory frameworks rather than federal acquisition regulations.
