Johns River in northern Maine.* The Dickey-Lincoln project is now in abeyance pending the resolution of this and a number of other environ- mental and economic questions. 6. Wound fin. Construction of the Warner Valley Dam is likely to decrease the flow in the Virgin River in southwestern Utah, which would threaten the existence of the woundfin, an endangered minnow found only in the Virgin River. Water stored behind the dam would be used to supply a 500 MW power plant and for use by the city of St. George, Utah. At present, this project is in a "hold" status pending further investigation by the FWS of actual instream flow requirements of the wound fin. Though one has not yet been reached, a compromise appears eminently possible. Even after the maximum flow requirements are reserved, enough water remains to supply the power plant, with con- siderable quantities left over for the city. 7. Whooping crane. In Nebraska et al. vs. Ray, ** an injunc tion was granted to prevent completion of Grayrocks Dam in eastern Wyoming. This was done partly because of the effects of increased water con- sumption by a power plant on the whooping crane habitat in the Platte River channel 300 miles downstream. A compromise was reached in which the power companies created a trust fund that may be used to purchase downstream water rights to replace the water used by the plant. 8. Colorado Squawfish. The Colorado River Water Conservation District has applied for a permit from the Federal Energy Regulatory Commission to construct the Juniper Dam on the Yampa River in northwest Colorado. In preliminary discussions, the FWS has disclosed that the dam will inundate an area inhabited by the Colorado squawfish and 'that a con- sultation may result in an unfavorable biological opinion. ,The project has apparently been shelved. *** DC'YI1cnf.(,,~.

This project would allegedly also destroy the nesting site of a pair of peregrine falcons, another endangered species. The squawfish, incidentally, is an example of an endangered species that may be doomed by previous al tera tions to its hab i tat (mainly introduced spec ies) . See Behnke, 1979. 15
