Table 7. Estimated cost to construct berms averaging four feet in height and to rip-rap portions of berms
<br />facing or adjacent to current (presumably one-half of the berm's length) for public ponds
<br />currently managed as sport fisheries by the Colorado Division of Wildlife. Shoreline
<br />development factors estimated visually from diagrams found in Elmblad and Satterfield (1995).

<br />rapped for one-half of their length within the 50 year floodplain of the Colorado River in the
<br />Grand Valley from Palisade to Loma. An overall estimated shoreline development factor of 1.5
<br />was used to calculate shoreline length based on pond surface area.
