Informal Fish Survey

 
 

Informal Fish Survey
in Lower Arana Creek


Conducted: Friday, May 21, 1999, 9:30 am - 3:30 pm

By: Jack Harrell, Monterey Bay Salmon & Trout Project Fish Trapping & Research Division and L.B., a Paul Sweet Road resident .

Survey began at culverts north of Santa Cruz Harbor continuing approximately 2 miles upstream to Paul Sweet Road (L.B.'s property). Jack wore wet suit, scuba gear, and used an underwater camera. L.B. wore chest high waders and used a machete to traverse the thick vegetation.

Trash:

  • Tires ~ 40

  • Cans / Batteries

  • Socks and Grocery Carts

 

 

Water Attributes:

  • Pools, riffles, and graves in a number of locations

  • 5' hidden water fall is a barrier to fish migration, however fry found above the falls (may be released fish).

  • Blue hazy color of water making for a cloudy turbidity.

  • Yellowish brown water flowing from tributary at the Oakwood cemetary

 

Conclusions:

  • Site of Homeless camp upstream from Brookwood Road crossing

  • Since no adult fish were seen, the chance of predation is great. Likely they have been eaten by racoon or by humans fishing or trapping them.

  • Arana is a viable habitat for salmonid. Concentrate habitat enhancement in pools and gravel areas where fry were counted.

  • Next year do an April survey to find adults. Historically this was probably home to 20 adult steelhead and trout.

  • Consider installing swinging bar covers over the four culverts at harbor to prevent seal predation.

  • Plan a stream cleanup.
