<br />APPENDIX A <br /> <br />SCOPE OF WORK <br /> <br />1. INTRODUCTION <br /> <br />The Corps of Engineers (COE) proposes to perform, or cause to <br />have performed, a hydrographic survey on Lake Crook. The <br />purpose of this survey is to collect hydrographic data when the <br />reservoir is at or above the normal/conservation pool elevation, <br />and convert this information into an area-elevation-capacity <br />table. All maps generated from this survey are related to this <br />purpose, and the COE makes no representation and assumes no <br />liability if this information is used for any other purposes, <br />such as boating maps. <br /> <br />In an effort to keep costs to a minimum, basic needs were <br />identified and are presented in the Specifications section <br />below. The rate schedule was generated from these basic needs. <br />Should the Sponsor require analysis beyond that identified in <br />the basic contract, that information can be provided at an <br />additional cost as identified in Section 6 - Cost Estimate. <br /> <br />2. LOCATION OF SURVEY <br /> <br />Lake Crook is located in Lamar County in east Texas. The dam <br />and lake are on Pine Creek approximately two miles north of the <br />city of Paris, Texas. The facility provides water supply for <br />Paris, Texas. Water-rights owner and operator of Lake Crook is <br />the city of Paris, Texas. The lake has a surface area of 1,226 <br />acres. <br /> <br />3. SURVEY PLAN, SPECIFICATIONS, AND ANALYSES <br /> <br />Surface acreage will be based on USGS 7.5 minute quadrangle or 1- <br />meter resolution digital ortho quarter quad (DOQQ) developed for <br />the Texas GIS Planning Council, if available. Positioning on the <br />lake surface will be established utilizing Differential Global <br />Positioning System (DGPS) with an estimated resolution of three <br />meters or better. Survey data will be collected from survey <br />lines spaced at approximately 500 feet. These lines will be <br />followed to the extent possible as permitted by obstructions. <br />Positioning and sounding data will be collected and stored <br />electronically at the rate of one measurement every second, or <br /> <br />5 <br />
