    This is a map of the 1:24,000 scale USGS hydrography in the Lower Garcia / Estuary sub-basin, overlaid on top of an elevation 
hillshade with KRIS Garcia sub-basins. The un-labeled stream at the northeastern edge of the sub-basin is Allen Creek. The 
steepest relief in this sub-basin is in the headwaters of that stream. Note that while Allen Creek is within this KRIS Garcia 
sub-basin, Olsen Gulch (which is the next upstream of Allen Creek on the right) falls into the North Fork Garcia Calwater Planning 
Watershed. Data were contributed by the California Department of Forestry. Scale = 1:70,842 .
