39s, b. Hydrographic Survey Cost Computation. The Texas Water Development Board computes Hydrographic Survey costs utilizing the following formula: 2 Rate = 0.0000014 X (Area) + 1.15 X (Area) + $13,000 = $14,412 (Area is the surface area of the lake at the time of the survey, in acres and Rate is the proposed cost of the survey). Lake Crook has a surface area of 1,226 acres at elevation 476 feet National Geodetic Vertical Datum. The estimated survey cost is therefore $14,500.00 (rounded up to the next $100.00). The cost of the survey and report are proposed as lump sum fees in accordance with the recorded surface areas and the standard rate schedule and represents the typical charges for a "standardized" underwater bathymetric survey for a given size lake and associated reporting of the findings. This standard charge schedule assumes: a surface acreage of the lake at normal pool elevation; an underwater bathymetric survey only; a 500 - foot average width between the surveying transects; acceptable weather conditions; no significant surface or sub - surface obstructions to navigation; no unusual owner - induced delays once the field mobilization and survey effort has been initiated; a coordination meeting with the owner; and a standard survey report consisting of a description of the lake and previously -known physical and storage conditions, description of the hydrographic survey methodology, narrative and tabular descriptions of the newly surveyed physical parameters of the lake bathymetry and storage capacity, representative cross - sections of the lake survey, a two- dimensional contour map and shaded relief plot of the lake bathymetry, and associated digital files of the survey results, if requested. c.
