Water Body San Simeon Creek Drainage San Simeon Creek Island Group Island
Depth Width 6 m Salinity 0 Gear 10 ft, 1/8 inch mesh seine
Locality San Simeon Creek, south fork

Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 17.5 C. Fish collected in a 25 m long pool. Small trout were very abundant. Downstream from here to junction with north fork. The stream has dwindled to a series of unconnected pools. The stream appears to be drying rapidly as we saw pool 1 cm deep with fish dying from lack of water, others were already dead.

Collecting Event Remarks Water temp. = 22 C. Garter snake seen. Males (sticklebacks) in nuptial coloration. Tadpoles present. Salmo gairdneri was found dead but in good condition (52.5 cm).

It appears that the water level has dropped at least 15 cm. Substantial portions of the habitat have dried up and the habitat may go dry by summer's end. Also caught Oncorhynchus mykiss, Eucyclogobius newberryi, and Cottus sp.

Locality San Simeon Creek, south fork
Latitude-Longitude 35.6296028°N, 121.0414417°W Bottom Type sand, algae
Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 22 C. All 5 scorable fish were low plated. 4 fish came from pool from which data above is presented, all were low plated fish. 7 fish came from a small puddle just upstream <1 cm deep and about 25 cm in diameter. This puddle was drying. 1 fish from this puddle was countable and it was low morph. A belostomatid was seen with a captured water strider, but I did not see it get captured. Downstream of here is a 3 m falls and access is poor in this area. Thus it is very unlikely that sticklebacks are introduced.

Collecting Event Remarks Water temp. = 23.5 C. Salmo gairdneri seen but not seined. Entosphenus was told to us to be here. No males with nuptial coloration. Most fish seined from large (60 m long) pool, reaching a maximum of about 2 m deep. While collecting following potential predators were observed: belostomatid, Thamnophis couchi, trout, pair of kingfishers flew over our head. Clemmys also present. This appears to be a permanent habitat. Even after drought water marks on cliff indicate drop of no more than 10 cm and water is flowing into and out of the pool. All Cottus and a few sticklebacks were collected in a shallow (<30 cm deep) pool just downstream. Also caught Cottus asper and Lampetra tridentata.

Collecting Event Remarks Water temp. = 18 C. This is a very isolated pool along a cliff face. The stream is almost entirely dry for several hundred meters downstream. The pool is probably always in shade, accounting for the low temp and high density of sticklebacks. Enough sticklebacks were obtained in 1 seine haul for a complete sample. Some large males had poorly developed nuptial coloration.
