The technique known as Network Analysis for Regional Information is used for a network of stream‐gaging stations in northwest Arizona in order to suggest a logical gaging strategy for the area. This procedure uses a Bayesian estimation scheme to arrive at the relationship between information content of a regional regression and the level of data availability (measured by the number pf stations and harmonic mean record length). Superimposed on this relationship is the relationship between estimated network operating costs for planning periods of 10, 20, and 30 years for alternative gaging strategies. These relationships are used to develop the relationship between expected information content of the network and estimated cost of network operation, which, in turn, can be used to suggest the best gaging strategy to pursue in an uncertain future.
