Pine Creek Dam was constructed in 1969 with the primary purposes of
controlling problematic flooding, providing drinking water, and providing
recreation. Today Pine Creek is the site of an important retrofitting proj-ect.
The Federal Energy Regulatory Commission issued a license (No.
12646) to the city of Broken Bow, Oklahoma to add hydro power to this
dam’s purposes. This work couldn’t start until USACE completes dam
Continental Mapping provided high-accuracy mapping of the Pine Creek
dam, through our IDIQ master contract with the USACE Tulsa District.
This area was approximately 620 acres and the data was used to sup-port
development of a GIS suite with parcel mapping, land use, flood-plain,
and wetland delineation.
Aerial imagery was collected using 4 band, color, and direct digital
imagery across the project site and required twenty-six photo control
points. Continental Mapping provided the District with topographic
and planimetric mapping, 1’ contours, and digital orthorectified
imagery with 6” resolution. Planimetric mapping included curbs,
paved and unpaved road, drives, sidewalks, buildings, manholes, catch basins, other
visible utilities, poles, fences, vegetation, hydrology, and miscellaneous features
visible in the imagery. The DTM supported a surface that met or exceeded ASPRS
Class 1 accuracies.
