Lidar-based DEMs, flowaccumulation and watersheds derived by r.watershed

Airphoto with 300ft grid with State plane coordinates [ft]
Airphoto with 300ft grid and contours
Airphoto with 300ft grid and contours with labels (sorry for the extra 0000, see that the banks are higher (80ft) than the terrain in the field (78ft)
Wider area showing benchmarks along the railroad and potential for flooding
Even wider area showing location of study site in relation to I-70
DEM with red arrows showing the dicthes(?), water depth distribution if there was no drainage
