The cost for <br />constructing a hatchery on this site could be between $8.3 and $8.6 million. <br /> <br />4.2.1 State Capabilities <br /> <br />Of the 11 sites evaluated, 3 are state facilities administered by each <br />of three Colorado River Basin States. The Logan FES is under the Utah <br />Division of Wildlife Resources; Rifle Springs SFH is under the Colorado <br />Division of Wildlife; and Page Springs SFH is under the Arizona Department <br />of Game and Fish. <br /> <br />All three facilities currently have production capability. The Logan <br />FES can probably produce about 50,000 fi ngerl i ngs per <br />year, based on past production levels of these rare fishes and the existing <br />rearing facilities. <br /> <br />The production capability of the Rifle Springs SFH is unknown since no <br />rare fish were ever transferred to that site for spawning or rearing. The <br />facility is designed with a hatch house, indoor fry rearing area, and <br />outdoor concrete raceways for primarily salmonid production. This hatchery <br />has several earthen rearing ponds that may be suitable for the rare fishes. <br />However, more information is needed on water quality, especially <br />temperatures, to determine the suitability of this facility. The Rifle <br />Springs SFH is currently restricted by the Colorado State Legislature from <br />spawning, holding, or producing any rare Colorado River fishes. <br /> <br />The Page Springs SFH is currently capable of rearing about 50,000 <br />razorback sucker from fry to small fingerlings for release in the wild. <br />This facility functions primarily as a warm-water fish hatchery. It has no <br />spawning, hatching, or incubation facilities, and relies on fry transferred <br />from the Dexter NFH. <br />
