Data loggers, equipment enclosures, radios and modems are needed to support the District’s data collection and telemetry systems. Campbell Scientific, Inc., has been developing and producing these instruments for more than 40 years. The Campbell product has been integrated into the Bureau of Water Resource Information’s (WRI’s) monitoring program and has proven to be highly reliable and an asset to the program. WRI has approximately 1,000 units deployed in the field. If the District used other data loggers from different sources, inefficiencies would result with regard to increased field staff time and additional training related to data collection and modification of existing data processing routines; there would be a need to develop an alternate, non-standard, hardware interface for use in the field; and there would be a potential for decreased data quality
