The Watershed Section is meant to provide a summary of detailed information available and provide a link and reference to other sources of additional in- depth information if desired. References to these sources are provided within the text and at the end in the References Section. 1.1 IRWM Accomplishments Since its adoption in 2006, the IRWM program has successfully helped facilitate the planning and funding of numerous projects that improve water management in the watershed and help achieve IRWM goals. Table 1 provides a list of projects and programs implemented since 2007 in the Santa Clara River Watershed as well as the IRWM goals that they help achieve. 5 WCVC IRWM Plan Update 2014 - Santa Clara River Watershed Section Table 1.

  • 3.12 Hydrology and Water Quality
    3.12 HYDROLOGY AND WATER QUALITY EXECUTIVE SUMMARY This section describes the drainage features, stormwater quality, flooding hazards, and flood-protection improvements within the City’s Planning Area. Regulatory agencies governing stormwater quality and flooding hazards are also discussed. The City’s Planning Area is comprised of the City’s boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is outside the City’s boundaries and adopted SOI. Together the City and County Planning Areas comprise the OVOV Planning Area. With implementation of the proposed General Plan goals, objectives, and policies potential impacts on hydrology and water quality would be less than significant. EXISTING CONDITIONS Surface Water Drainage Patterns within City’s Planning Area Surface water drainage patterns are dependent on topography, the amount and location of impervious surfaces, and the type of flood control that is located in an area. The size, or magnitude, of a flood is described by a term called a “recurrence interval.” By studying a long period of flow record for a stream, hydrologists estimate the size of a flood that would have a likelihood of occurring during various intervals. For example, a five-year flood event would occur, on the average, once every five years (and would have a 20 percent chance of occurring in any one year). Although a 100-year flood event is expected to happen only once in a century, there is a 1 percent chance that a flood of that size could happen during any year.

  • Aquifers East Subbasin
    JUNE 2020 OF THE SANTA CLARA RIVER VALLEY AQUIFERS EAST SUBBASIN Anatomy of an aquifer An aquifer is an underground reservoir where water fills and moves between the voids in rocks, silt and other material. Many different types of sediments and rocks can form aquifers, including gravel, sandstone, and fractured limestone. Aquifers are fed by rain and runoff, which percolates downward. There are two main types of aquifers: unconfined and confined. Unconfined, or alluvial aquifers, lie below a permeable layer of soil. Confined aquifers occur beneath an impenetrable layer of rock or clay. RECHARGE AREA DISCHARGE AREA PUMPED WELL STREAM Unconfined Aquifer Confining Bed (aquitard) Confined Aquifer CENTURIES Confining Bed (aquitard) MILLENNIA Confined Aquifer Slowing the flow Natural groundwater filter Aquitards are geological formations of semi-permeable material, like silts and clays that separate one part of an aquifer from Aquifers naturally filter groundwater by another, limiting the ow of water between geological forcing it to pass through small pores formations. and between sediments, which helps to remove substances from the water. Find more information at scvgsa.org AQUIFERS OF THE SANTA CLARA RIVER VALLEY EAST SUBBASIN Groundwater in the Santa Clarita Valley SCV Water gets half of its total supply from two aquifers. The shallow alluvial aquifer lies beneath the Santa Clara River and its tributaries; the larger, deeper Saugus Formation aquifer sits beneath the entire Santa Clarita Valley. Of the 35,900 acre-feet of total groundwater pumped in the Santa Clarita Valley in 2018, about 26,450 acre-feet came from the alluvial aquifer and 9,450 acre-feet were pumped from the underlying Saugus Formation.

  • Ventura County
    Steelhead/rainbow trout resources of Ventura County Rincon Rincon Creek consists of about 9.7 stream miles. It flows southwest, entering the Pacific Ocean at Rincon Point. The culvert at the Highway 101 crossing is a total passage barrier (Stoecker et al. 2002). A watershed plan prepared for Rincon Creek includes a review of historical steelhead information. The review notes O. mykiss stocking occurred in the 1940s and subsequently. Anecdotal accounts of trout observations from the 1950s to the 1980s also are included (Tetra Tech 2007; Stoecker et al. 2002). Rincon Creek was surveyed in 1993 and no fish were observed. The survey report states, “Sediment inputs from Casitas Creek are destroying downstream habitat” (Unknown 1993). A 1994 DFG memo relayed the results of surveys from that year. The memo states, “The Wheeler Fire [in 1985] could have been the event that eradicated rainbow trout from Rincon Creek, although there is anecdotal information from a landowner along Rincon Creek that suggests that the population was extirpated as early as the 1960’s” (DFG 1994a). The memo adds, “It appears that the Highway 101 culvert has prevented the recolonization of rainbow trout/steelhead in Rincon Creek” (DFG 1994a). Consultants surveyed Rincon Creek as part of a steelhead study, and observed O. mykiss likely representing one year class in 2001 (Stoecker et al. 2002). A 2002 memo from NMFS staff states, “Rincon Creek provides approximately 4 miles of steelhead spawning and rearing habitat…” (NMFS 2002a). A 2002 study report notes water quality impacts on Rincon Creek from the large sediment load carried by Casitas Creek, a tributary (Stoecker et al.

    NEW OBSIDIAN SOURCING RESULTS FOR INTERIOR VENTURENO CHUMASH SITES: THE OAKBROOK PARK/LANG RANCH EARLY SITES DEBORAH V. ROMAN VENTURA COUNTY ARCHAEOLOGICAL SOCIETY As new radiocarBon dating reveals the antiquity of interior sites abutting the Santa Monica Mountains, this updated record of obsidian sourcing contributes to a re-evaluation of the antiquity of purported trade routes and sources utilized by the Early Period Ventureno Chumash. With the recent publicAtion of new AccelerAtor Mass Spectrometry dates for numerous interior sites abutting the Santa Monica Mountains, our scope of research at the Lang Ranch Project has expanded to review new X-ray fluorescence (XRF), portable X-ray fluorescence (pXRF) And Neutron ActivAtion AnAlysis (NAA) sourcing of obsidian that has been recovered from these sites (Roman 2017). Our case study of three sites exAmines the relationship between the evidence for the sources of this mAterial And considers its correlation with the early dates from these sites, as well as summarizes pAst hypotheses About the specific routes thAt were utilized to procure the mAterial. In Addition, we exAmine the evidence for hypothetical trade routes based upon early reports of Native American trails from Farmer (1935) and Van Valkenburg (n.d). AlternAtively, we Acknowledge cAutions issued by vArious scholars regArding the over- utilization of various proxies that have been extrapolated as evidence for long-distance trade. In 2017, RomAn reported on A new series of AMS radiocarbon dates that were recovered for the interior sites of CA-VEN-1029, -852, and -853 (Roman 2017).

Santa Barbara • Michael Wangler – Department of Science and Engineering, Cuyamaca College 3 Executive Summary With majestic mountains, dramatic coastlines, and a remarkable diversity of wildlands from alpine forests to desert scrublands, Southern California’s four national forests – Los Padres, Angeles, San Bernardino, and Cleveland – are beloved by millions of backpackers, hikers, birdwatchers, hunters and fisherman, and outdoor enthusiasts. Scientists recognize our region as one of the richest areas of plant and animal life on the planet. It is home to roughly 3,000 plant and 500 animal species, many of which are found nowhere else on Earth. Our national forests form the backbone for the conservation of the natural beauty and extraordinary biological diversity of the region. One of the great pleasures of hiking in the forests is to see this diversity, from rare butterflies, fish, frogs, and birds to mule deer, bighorn sheep, and bobcats.
