Map: L. Fish Distribution, Arcata Sub-basin |
|
This is a map shows the distribution of salmonids in the Arcata sub-basin. Chinook and steelhead distribution were obtained from NOAA. Potential coho habitat was
calculated from stream gradient. Gradients less than or equal to 4 percent from the outflow were selected and saved. Any gradient steeper than 4% served as a cutoff
for any further potential migration up stream. These data are preliminary only, and were produced with the understanding that coho salmon are able to leap greater
than 4% for short distances. Therefore, the data are considered conservative estimates.
