• <br />Section III. <br />INVENTORY OF PUBLIC AND PRIVATE POND OWNERS <br />The objective of this effort is to identify the owners of private and public bodies of standing water <br />adjacent to the upper Colorado River from Rifle to state line and adjacent to the Gunnison River. <br />Additionally, information was collected on each pond to determine Warne of adjacent river, <br />location along the river to nearest landmark, side of river facing downstream, surface are of pond, <br />water source, outlet type, connectivity to river, year pond last flooded, uses of pond, fish species <br />present, and stocking history of each pond. <br />Methodology: <br />• <br />• <br />Tye horizontal and vertical study area limits could not be established as described in the scope of <br />work provided to this project. Delineation of the 50 and 100 year flood plain does not exist far <br />most of the study area included in this effort. This effort employed the definition for study area as <br />all ponds within 1 mile of the river in areas of law adjacent landform gradient and all ponds within <br />0.5 miles of the river in areas of high adjacent landform gradient. No limitation was placed on <br />pond size. Ponds were identified on existing aerial photography in areas where the photography <br />was available. Existing maps were used to identify ponds in areas where aerial photography was <br />not located. <br />Identified ponds were encoded using a system that identified the river corridor (Colorado or <br />Gunnison), county, side of river facing downstream (left or right), and number of pond upstream <br />from confluence with state line or other rivers. Pond surface area was estimated utilizing a <br />Planix 5000 digital direct readout planimeter. Inlets and outlets were identified from photos if <br />possible. Other information fields developed include name/address/telephone number of pond <br />owners, surface area, water source, outlet type, year last flooded, connection to river, use, fish <br />species present, and stocking history. All information gathered on each pond was assembled in <br />the Q and A database program developed by Symantec. <br />Pond owners were identified from aerial photographs and county tax assessors/clerks offices. <br />Identified ponds were matched to USGS 7.5 minute quadrangle maps. These locations were then <br />correlated with existing parcel numbers available from the tax records of Mesa, Garfield, and <br />Delta county, Colorado. Areas within the study area that did not have aerial photography <br />available required identification of all parcel numbers within the study area. This aspect of the <br />research will provide future identification efforts with the database required. to identify pond <br />owners in these areas.. <br />Development of the database required far each pond owner was completed by administering a <br />mail questionnaire (See Exhibit 1). The questionnaire was sent to each private pond owners as <br />identified through county records. Participants were given 21 days to respond. Participants were <br />7 <br />
