STRUCTURAL MEASURES <br />The proposed structural measures to meet the sponsors present needs <br />consist of lateral realignment and lining, head gates with parshall Flumes, <br />road culverts, and one pumping plant located at,Smith Reservoir.. <br />The following table shows proposed structural needs by laterals: <br />Needs by Laterals <br />Heaa uu.L- Turnout G t i.e ctrl c <br />Luting Gates verts.

The Irrigation Company <br />has prescriptive landrights for the canals and laterals. There is no <br />apparent need for and no costs have been estimated ,for relocation <br />assistance and real property acquisition. <br />Current cost - sharing from P.L. 566 funds are: local organizations <br />must pay at least 50 percent of the construction cost allocated to <br />structural works of improvement for irrigation, acquire and pay for all <br />necessary land and water rights, and defray costs of operation and <br />maintenance. Project construction costs are estimated to be $489,240; <br />$244,620 would be borne by P.L. 566 funds and $244,620 by other funds. <br />In�itallation costs are estimated to be $648,900; about $391,390 (60.3%) <br />would be borne by P.L. 566 .funds and $257,510 (39.7 %) by other funds. <br />4 <br />
