Polk commissioners decided on Monday by a 3-2 vote to hold off on installing a stream gauge on the Green River that would have cost $36,000 the first year. The United States Geological Survey was going to contribute $5,000 for the first year&squo;s cost. The county was looking at annual maintenance costs after the first year of $14,000. Commissioners Tommy Melton and Warren Watson voted in favor of the stream gauge, while commissioners Cindy Walker, Ray Gasperson and Rene´ McDermott said they felt the gauge is important but not an immediate need in the current economic situation.
