The map documents the critical infrastructure of the Portneuf Marsh Valley Irrigation Company Feeder Canal, which directs water through the southern basin. The northern terrain is marked by significant drainages including Twentyfour Mile Cr and Wood Cr, which descend from Sawmill Ridge toward the Portneuf River valley.
