Southern California Steelhead ESU - Historic Stream Bed Habitat Distribution

Stream / Tributary	Species¹	Historic Upper Limit of Run / Comments	Sources References/ Pers. comm.

SOUTHERN CALIFORNIA ESU - STEELHEAD Listed as an endangered species on 8/18/97. The ESU includes all naturally spawned populations of steelhead (and their progeny) in streams from the Santa Maria River to Malibu Creek.
Beginning in the 1890's and extending through the late 1930's, fingerling rainbow trout were planted into almost all possible waters in southern California. Included were stocks identified at the time as both rainbow trout and steelhead (Swift et. al. 1993).
Santa Barbara County (Line follows the Santa Maria R. and Cuyama R.)
Santa Maria R.	SH-W	Described by Shapovalov in 1944. The Santa Maria River is formed at the confluence of the Cuyama and Sisquoc Rivers, ~40km upstream from the Pacific. Stream flow in the main river was historically interrupted and intermittent throughout the year especially during the summer except in some headwater tributaries where perennial flow occurs (Manzana Cr., South Fork Sisquoc R.). Other factors affected habitat, such as forest fires, which increased runoff and erosion, and groundwater pumping and surface diversions, which reduced available stream flows. Steelhead used the main river primarily as a migratory route to the tributaries. Adults entered with the first heavy rains of the season (Dec.-Mar.). Few details found regarding historic spawning areas and run size. Rescued juvenile steelhead from the Santa Ynez were planted during 1940-1944 and possibly in 1945 and 1946. The last sizable run of steelhead was in 1941 with a few adults reported in 1942-1943. Seven years of drought and the completion of Vaquero Dam in late 1950's @ 6.5 miles (11 km) up the Cuyama River created unreliable flows.	Shapovalov 1944b Evans 1951
Cuyama R.	SH-W	No historical account of steelhead distribution in Cuyama River. Headwater tributaries managed for catchable trout and stocked with hatchery trout (Alamo Cr. - 1947; Beartrap Cr. - 1944 and 1947; Reyes Cr. - 1933, 1941-1948).	Titus et al. 2000
Los Alamos Cr.	?	Planted with juvenile steelhead rescued from the Santa Ynez River from 1940-1942. Creek has perennial flow and now forms one of the arms of Twitchell Reservoir.	Shapovalov 1944b
Sisquoc R.	SH-W RT	Used more heavily by steelhead for spawning than the Cuyama R.. Historically known for its sports fishery of trout and steelhead. Local newspaper articles from 1890 commented on plentiful "trout". 1959 stream survey indicated self-sustaining population of trout and therefore suitable stream conditions for steelhead although none were mentioned. A 1964 survey during the low flow period indicated fewer trout were found due to poor water conditions, and the upstream movement of anadromous fish was not possible because of intensified water use. SH juveniles planted in 1930.	Shapovalov 1944 Richardson 1959 Whalls 1964 Swift, pers. comm.
Tepusquet Cr.	?	Planted with 73,800 juvenile steelhead from the Santa Ynez River during 1940 to 1944.	Shapovalov 1944b
La Brea Cr.	SH-W	Know as a spawning area for steelhead. Spawning and rearing habitat was influenced by forest fires in the 1920's which increased sediment loads and filled in pools in the stream.	Shapovalov 1944b
Manzana Cr.	?	Perennial flows present. In 1930, ~15,000 hatchery steelhead were planted as were rainbow (10,000 in 1930, 4,500 in 1941-1942. Approximately 47,240 juvenile steelhead were rescued from the Santa Ynes and were planted from 1940 to 1944.	Titus et al. 2000
Davy Brown Canyon Cr.	?	Tributary to Manzana Cr. Approximately 103,600 juvenile steelhead rescued from the Santa Ynez River were planted from 1941 to 1944 (also, 1,900 rainbow trout in 1941-1942).	Titus et al. 2000
South Fork Sisquoc R.	?	Tributary to Manzana Cr. Approximately 10,000 hatchery reared steelhead were planted in 1933 (3,200 hatchery rainbow trout in 1942)	Shapovalov 1944b
San Antonio Cr.	?	No historic information found regarding steelhead populations. Juvenile steelhead rescued from the Santa Ynez River were planted in 1944. Stream flows through portions of Vandenberg Air Force Base.	Titus et al. 2000
Santa Ynez R.	SH-W	Habitat availability was unchecked until Gibraltar Dam (~69.5 mi. upstream) was constructed in 1920. Historically, the Santa Ynez system supported the largest steelhead run in southern California and was famous for its sport fishery. Local newspaper accounts from Aug. 1891 reported "great schools of young salmon" were seen coming in from the ocean. In 1944 Shapovalov described the tributaries as drying in the lower reaches, but maintaining perennial flows or standing water in pools in the upper reaches. Mainstem dried up during May through July except for a stretch of river near Solvang, at the lagoon, and occasional deep pools. Despite unstable flow conditions (forest fires, water storage, water diversion and groundwater pumping), flows in the lower Santa Ynez from 1928-1944 (excluding 1929 and 1931 drought years) allowed steelhead passage to spawning areas. No counts of adult runs were made. Juvenile SH rescues were conducted in 1939-40,'42-'46. Nearly all fish were young-of- the-year, and emigrated at ~ age of 1 year. Juvenile SH were planted in the lower Santa Ynez River - mostly at the lagoon and/or near Solvang, with many distributed throughout the region. Hatchery reared steelhead (1930-1935) and rainbow trout (1930,1945, 1950-1953) were also planted. The last reported substantial run and catches of steelhead occurred in 1945-1946. In 1946-1947, steelhead were observed waiting for the sandbar to breech, which never occurred and no spawning occurred that year. Cachuma Dam (currently known as Bradbury Dam) ~45.5 mi. upstream (1953) further altered river flows.

Santa Ynez Lagoon	SH-W	Juvenile SH from Fillmore Hatchery in Ventura Co. were used in a lagoon stocking experiment, planted directly into the lagoon in 9/40. Juvenile steelhead rescued in the Santa Ynez River were planted in the lagoon from 1940-1947. Last stocked in 2/54 with poor results. Steelhead (20-40) were observed in 3/56 at the lagoon.

Tequepis Canyon Cr.	SH-W	Steelhead used stream for spawning prior to the construction of Bradbury Dam in ~1953.
Santa Cruz Cr.	SH-W	Steelhead used stream for spawning prior to the construction of Bradbury Dam in ~1953. Creek was stocked with juvenile SH in 1932 and 1939. Some ~10,000 juveniles were rescued from the creek in 1939 and 1940.	Shapovalov 1944a
Peach Tree Cr.	?	Historically not accessible to steelhead because of an impassible waterfall on Santa Cruz Creek. Juvenile SH were planted from the Santa Ynez River in 1939-1944.	Shapovalov 1944a
Location of Gibraltar Dam, in relation to Santa Ynez tributaries. Completed in 1920
Gibraltor Reservoir	Land Locked SH-W	Landlocked steelhead, 2-4 years old and 13-39 cm, were captured in the reservoir in 1937. The reservoir supported a population of land locked steelhead native to the Santa Ynez drainage as well as hatchery reared fish which were planted in1932, 1933, 1934, 1935 and 1936. RT were stocked in 1932. SH from the Santa Ynez were rescued and placed in the reservoir in 1939 (9,000), 1940 (195,000) & 194? (25,440).	Shapovalov 1944a
Gidney Cr.	Land Locked SH-W	Suitable spawning grounds identified in a 1937 survey. Small spawning run occurred in February 1937. Gidney Creek was unsilted and contained surficial flow later into the season. Blocked to ocean access in 1920 by Gibraltar Dam.	Curtis 1937
Camuesa Cr.	?	Apparently not used by steelhead for unknown reason. Blocked to ocean access in 1920 by Gibraltar Dam.	Curtis 1937
Mono Cr.	Land Locked SH-W	Blocked to ocean access in 1920 by Gibraltar Dam. Suitable spawning grounds identified in a 1937 survey up to the "debris dam". Small spawning run occurred in February 1937. Siltation and desiccation were mentioned as potential problems with spawning.	Curtis 1937
Indian Cr.	SH-W	Steelhead spawning occurred before construction of Gibraltar Reservoir in 1920. Forest fires since the 1920's either directly reduced steelhead populations or degraded habitat by erosion and siltation. Juvenile SH were planted in 1945.	Titus et al. 2000 Shapovalov 1944a Curtis 1937
Buckhorn Cr.	SH-W	Forest fires since the 1920's either directly reduced steelhead populations or degraded habitat by erosion and siltation.	Titus et al. 2000 Shapovalov 1944a

Tecolote Canyon Cr. (Tecolote Cr.)	SH-W	Historically, steelhead had access to the lower 6 miles (10km) of stream, at which point a 18ft (6m) waterfall blocked passage of the remaining 3 miles (5km) of stream in the Los Padres National Forest. The historic steelhead population was lost when early landowners pumped the creek dry.	Titus et al. 2000 Gantt 1973

Ventura County
Rincon Cr.	SH-W	Historically known as a steelhead stream, but few details exist. A 1934 CDFG survey showed the creek had recovered from input of sediment from a fire although the upper watershed was not prone to erosion. Juvenile steelhead from the Santa Ynez River and hatchery reared rainbow trout were planted in the 1940's.	Titus et al. 2000
Casitas Cr.	SH-W
Los Sauces Cr.	?
Ventura R.	SH-W	Supported a large and consistent steelhead run until the late 1940's, especially during years when rains were sufficient to keep the sand bar open for at least a week or more. Foster Park Diversion on lower mainstem completed in 1906. A 1934 survey showed steelhead present, with mainstem primarily serving as a migration corridor to the tributaries. Prolonged drought (into the late 1940's) and construction of Matilija Dam (1948) contributed to decline of population. CDFG (1946) noted the presence of juveniles and estimated 4,000-5,000 steelhead spawning in the river with about half of those using area above proposed dam (12 miles of spawning area). In 1958 the construction and completion of Casitas Dam (Coyote Cr) and Robles Diversion Dam reduced reliable flows for steelhead passage and spawning. Planting of steelhead and rainbow trout dates back to 1878 with more frequent plants from 1930 to1945. Survey dates include: 1934,1946,1947, 1950,1955, 1958.

Ventura River Estuary	SH-W	Juveniles were observed in the lagoon in 1947. In 1849, settlement began along the eastern shore; by 1870, lands on both sides were in agricultural and ranch production.	Titus et al. 2000
Coyote Cr.	SH-W	Surveys in the mid-1930's showed both rainbow trout and juvenile steelhead were present and supplemented with hatchery stock. Juveniles were rescued from the lower portions of the creek in dry years. Habitat appeared to be doing well prior to a fire in 1932. The 1945 run was estimated at least 2,500 adults, with an average run of 3,000 adults. Historic spawning habitat was poor 2.8 mi (~4.8 km) above the confluence (at proposed El Rancho Cola dam site). About 7 mi (11 km) above Hwy 150 was available for spawning. Present day Casitas Dam was completed in 1958, ~ 7 mi. above the mouth of the Ventura River.	Titus et al. 2000 Evans 1951 Clanton & Jarvis 1946 Clanton & White 1945
Santa Ana Cr.	SH-W	Tributary to Coyote Creek with historic spawning and rearing. Approximately 6.4 km above Hwy 150 was available for spawning.	Titus et al.1994
San Antonio Cr.	?	No formal record of historic steelhead run. Rescued steelhead were planted in 1944 (Gridely Canyon & Howard Canyon). RT stocking records from 1943-1947.	Titus et al.1994
Lion (Canyon) Cr.	?	Tributary to San Antonio Cr., was stocked with hatchery reared steelhead in 1938. No record of historic steelhead run. Access blocked by a dam about 6-8km east of Ojai (1949 CDFG field note).	Titus et al.1994
Gridley(Canyon) Cr.	SH-W	Historic steelhead run disappeared with the development of Ojai. Following the 1969 floods, no trout were observed.	Moore 1980c
Senior (Canyon) Cr.	?	Stocked with hatchery trout at least as early as 1945.	Titus et al.1994
Thacher Cr.	?
Revees Cr.	?
Matilija Cr.	SH-W	Held one of the most productive spawning grounds (19 km) for the Ventura River in 1946. Completion of the dam in 1948 blocked steelhead access. Fish passage facility was built in 1947 and renovated in 1965, with dam modification work. Supplemented with juveniles in 1938, 1944 and 1945. Trout stocking records date from 1939, 1942-1948. About 50% of the spawning in the Ventura River occurred upstream of Matilija Dam. A trap and truck facility was constructed to transport fish above the dam. The operation trapped 7 adult steelhead and lasted only for one year. In 1958 anglers reported the presence of adult steelhead in February and March.	Titus et al.1994 Clanton & Jarvis 1946
N.F. Matilija Cr.	SH-W	Estimated in 1946 that <2% of Ventura River steelhead use the North Fork for spawning. A waterfall removed in 1944 added ~3.4 miles (5.6km) of habitat which was unused due to low flows and lack of suitable spawning habitat. Stocked intermittently from 1938-1954 (1944 from the Santa Ana Creek). Trout stocking records date from 1939, 1942-1947. 40 flow constrictors were constructed in 1955.	Titus et al. 2000 Clanton & Jarvis 1946
Murrieta Cr.
N.F. Ventura R.
Santa Clara R.	SH-W	Upriver extent of steelhead not pinpointed, but steelhead perhaps used the upper reaches. Supported a popular winter steelhead sport fishery, with an average annual run of ~9000 adult steelhead. Since the 1950's unscreened water diversion near the town of Saticoy has effectively blocked upstream migration of adults and entrained emigrating smolts. Early records show intermittent stocking from 1938-1948 (1944 -from Santa Ynez R.).	Titus et al. 2000 Moore 1980a Kreider 1948 Hubbs 1946
Castaic Cr.	?	No steelhead found in 1978 seining survey.	Titus et al. 2000

Santa Paula Cr.	SH-W RT	Upper historic limit of spawning not mentioned, though 11 miles of habitat listed (Moore). Harvey Dam was built prior to 1910 (~6 ft.), fish ladder built circa 1939 and effective until the 1969-70 floods created 25' barrier. Historically a major spawning tributary for Santa Clara River steelhead. Juvenile steelhead and rainbow trout noted in a CDFG mid-1930's survey. Reach above Santa Paula Diversion was managed as a catchable rainbow trout fishery with stocking back to 1930. Steelhead juveniles were stocked intermittently from 1930-1943.	Evans 1951 Moore 1980b
Sisar (Canyon) Cr.	SH-W	No mention of natural run of steelhead using stream historically. Steelhead juveniles planted in 1938. Suitable spawning habitat and young-of-the-year steelhead noted in 1947 CDFG survey.	Titus et al.1994
Sespe Cr.	SH-W	Major area of historic spawning runs, with 53 miles habitat available (Moore). Stream historically managed for rainbow trout. Steelhead juveniles planted intermittently from 1930-1944 (juveniles rescued from the Santa Ynez R.). Surveys showed the presence of juvenile steelhead (1937 and 1949), and adults (1947 and 1953-54).

Solstice (Canyon) Cr.	SH-W	Upper limit of run not mentioned. Photographs of 24" steelhead were taken in the 1920's. Ron Rindge, long time resident, reported seeing adult steelhead whenever he visited the creek pre-1940. Anecdotal reports indicate steelhead present until 1947 when Pacific Coast Highway was widened and permanently blocked migration.	Manion, pers. comm. Manwaring 1999 Spina & Johnson 1999
Trancas (Canyon) Cr.	SH-W	Anecdotal reports of silver "salmon and steelhead" catches pre World War II.	Manwaring 1999
Ramirez (Canyon) Cr.	SH-W	Anecdotal report of trout fishing circa 1940.	Manwaring 1999
Willow Cr.
Malibu Cr.	SH-W	Upstream migration blocked by Rindge Dam in 1924. Relatively large steelhead run in 1947. Malibu Cr. State Park has had hatchery rainbows planted regularly.. Historically zero flow conditions occurred in the lower reaches of the creek but not since the late 1960's when Tapia Water Reclamation Facility opened and urban runoff enhances summer flows.	Orme, 1991 Titus et al. 2000 Manwaring 1999
Malibu Lagoon	SH-W	Pristine prior to the 1900's. Rindge Railroad line filled part of lagoon in 1908, used as dumpsite in 1929 state highway construction, filled for baseball and parking in 1960's. Now 92 acres, historic was several times larger. Historically, breaching of sand barrier occurred in winter/spring runoff but year-round flows (from 1960s to 1999) created by artificial discharge altered this regimen.	Ambrose et al. 1995
Cold Cr.	SH-W	Upper limit of run not discovered, with natural barriers present. Spawning was known to occur in lower reaches before Rindge Dam blocked access in 1924.	Titus et al. 2000
Las Virgenes Cr.	SH-W	Upper limit of run not discovered. Spawning occurred in lower reaches before Rindge Dam blocked access in 1924.	Titus et al. 2000
Triunfo (Canyon) Cr.	SH-W	Malibou Lake constructed in 1923 at the outlet of sub-basin. Other dams constructed throughout the upper watershed include Eleanor built in 1881, Sherwood in 1904, Crags in 1913, and Westlake in 1965. Trout farm and fishing pond on creek above falls from the 1930's to the 1980's. Trout caught below the falls in the 1950's.	Manion, pers. comm. Manwaring 1999 Orme 1991
Lobo (Canyon) Cr.	SH-W	No mention of upstream distribution, adults observed by local resident in lower reaches.	Dave Brown, as cited by S. Manion

1/ Species: SH-W = Steelhead, winter-run. RT = Rainbow trout. While both are of the same species (Oncorhynchus mykiss), it is important to distinguish the landlocked, resident (RT) form from the anadromous (SH) form for the purpose of NMFS's jurisdiction. ? = presence of historic SH or RT populations not clear.
