Whether you are planning to go camping, fishing, hiking, boating, picnicking, snow­ mobiling, cross country skiing or sight seeing, the choices for recreation are almost unlimited. Recreation plus… During the late spring, summer and early fall, the McCloud River is the most popular attraction in this area, offering fishing, swimming, camping and spectacular scenery. During the winter months, snowmobiling, cross country skiing and downhill skiing are the top ranking outdoor opportunities. Developed campgrounds and facilities… Except for Harris Springs, Cattle Camp, Trout Creek Campgrounds and Lake McCloud Boat Ramp, all developed campgrounds and day use facilities are located along the McCloud River. All campgrounds are on a first come-first served basis and have a 14 day stay limit. River route… The McCloud River parallels Highway 89 from its source near Dead Horse Summit to Fowler’s Campground. There it turns south and continues through private property to Lake McCloud. At Lake McCloud, the river again flows through National Forest lands to a point several miles below Ah-Di-Na Campground, plus several other areas downstream to the McCloud Nature Preserve. From here, the river passes through mostly private property and public access is extremely limited until the river enters Shasta Lake. Dispersed camping… If the improved campgrounds around McCloud are too crowded and confining, you may want to try camping somewhere else.

  • Pit River and Rock Creek 2012 Summary Report
    Pit River and Rock Creek 2012 summary report October 9, 2012 State of California Department of Fish and Wildlife Heritage and Wild Trout Program Prepared by Stephanie Mehalick and Cameron Zuber Introduction Rock Creek, located in northeastern California, is tributary to the Pit River approximately 3.5 miles downstream from Lake Britton (Shasta County; Figure 1). The native fish fauna of the Pit River is similar to the Sacramento River and includes rainbow trout (Oncorhynchus mykiss sp.), sculpin (Cottus spp.), hardhead (Mylopharadon conocephalus), Sacramento sucker (Catostomus occidentalis), speckled dace (Rhinichthys osculus) and Sacramento pikeminnow (Ptychocheilus grandis; Moyle 2002). In addition, the Pit River supports a wild population of non-native brown trout (Salmo trutta). It is unknown whether the ancestral origins of rainbow trout in the Pit River are redband trout (O. m. stonei) or coastal rainbow trout (O. m. irideus) and for the purposes of this report, we refer to them as rainbow trout. The California Department of Fish and Wildlife Heritage and Wild Trout Program (HWTP) has evaluated the Pit River as a candidate for Wild Trout Water designation since 2008. Wild Trout Waters are those that support self-sustaining wild trout populations, are aesthetically pleasing and environmentally productive, provide adequate catch rates in terms of numbers or size of trout, and are open to public angling (Bloom and Weaver 2008). The HWTP utilizes a phased approach to evaluate designation potential. In 2008, the HWTP conducted Phase 1 initial resource assessments in the Pit River to gather information on species composition, size class structure, habitat types, and catch rates (Weaver and Mehalick 2008).

My own fieldwork in 1970-74 disclosed fundamental inadequacies of these publications, as reported in Nevin (1991). We substantiate this finding, investigate its probable bases, and establish why my own data are not subject to the same difficulties. After this cautionary tale about the perils of restating a published grammar, we define a phonemic representation for utterances in the language and introduce Optimality Theory (OT). We then apply OT to a series of problems in the phonological patterning of the language: features of syllable codas, restrictions and alternations involving voiceless release and aspiration, and reduplicative morphology. Appendix A describes the physiology and phonetics of laryngeal phenomena in Pit River, especially epiglottal articulation that has in the past been improperly described as pharyngeal or involving the tongue radix (the feature RTR).

This Project would increase the existing height of Shasta Dam by 18.5 feet and purportedly expand the capacity of Shasta Lake by up to 634,000- acre feet. In response to this solicitation, the Winnemem Wintu Tribe (WWT) issues the following comments, assertions, and raises questions about the project’s legality. From reading the IS/NOP WWD does not define who is actually the proponent of the project. A lay person reading the IS/NOP would get the impression that it is WWD who will carry out this project, yet WWD makes no distinction. No proponent is identified. This omission renders the project description as deficient. The Project proponent must also be identified in order that transparency is maintained by WWD. Who is funding this EIR effort? If the EIR finds that the Project must be amended to avoid, lessen or mitigate environmental effects, who will amend the Project? Also, from reading the IS/NOP it appears that WWD has made no initial findings of its own, but relies heavily if not entirely on Reclamation’s SWLRI Final EIS released in 2014, and Reclamation’s SWLRI Final Feasibility Report released in 2015.

  • Report Lists Norcal's Mccloud River Among
    Report Lists NorCal’s McCloud River Among Nation’s ‘Most Endangered’ Jefferson Public Radio | By Erik Neumann Published April 13, 2021 at 4:40 PM PDT The McCloud River in Northern California is included in American Rivers' list of America's Most Endangered Rivers of 2021. Tracey Diaz Via American Rivers The McCloud River in Northern California is among the nation’s most endangered, according to a new report from the conservation group American Rivers. In a report released Tuesday, the McCloud was chosen as a river with significance to local people and wildlife, and because the federal Bureau of Reclamation wants to raise the height of Shasta Dam. “At this particular moment there has been a proposal to rise that dam another 18.5 feet. That would inundate three quarters of a mile more of the McCloud River,” says Amy Merrill, a California representative of American Rivers. The McCloud feeds into the Sacramento River, which is blocked by the 600-foot-tall Shasta Dam. It stores 41% of the water for the Central Valley Project, which supplies water for irrigation and for the metro areas of Sacramento and San Francisco. But upriver, the McCloud supports a series of rare and threatened species including the Shasta snow-wreath, Pacific fisher, Shasta salamander and McCloud River Redband Trout. It’s also the ancestral home of the Winnemem Wintu tribe, whose population is approximately 150 people. The tribe is also opposed to increasing the dam height. If the dam were raised it would further flood more than 40 cultural sites, according to the tribe.

  • A New Early Jurassic Marine Locality from Southwestern Chubut Basin, Argentina

September, 2015 Andean Geology doi: 10.5027/andgeoV42n3-a0410.5027/andgeoV40n2-a?? www.andeangeology.cl A new Early Jurassic marine locality from southwestern Chubut Basin, Argentina * S. Mariel Ferrari1, Santiago Bessone1 1 Centro Nacional Patagónico (CENPAT), Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Boulevard A. Brown 2915, Puerto Madryn 9120, Chubut, Argentina. [email protected]; [email protected] * Corresponding author: [email protected] ABSTRACT. A shallow marine invertebrate association is reported from a new Early Jurassic locality namely La Casilda, which is situated in the southwestern region of the Chubut Basin (Patagonia, Argentina). The marine deposits of La Casilda are located in the Río Genoa valley and bear a diverse invertebrate fauna including bivalves, gastropods, brachiopods, echinoderms and corals. A preliminary taxonomic analysis of the invertebrate fauna suggests that La Casilda deposits belong to the Mulanguiñeu Formation of late Pliensbachian-early Toarcian age, and may be coeval with those from the marine localities previously sampled in other regions of the Río Genoa valley. The preliminary results of a biodiversity analysis displayed that La Casilda is one of the most diverse localities at the Chubut Basin and could be assigned to the biofacies at the mixed siliciclastic-carbonate ramp proposed for the marine Early Jurassic at the Andean Basin of northern Chile. The evolution of the marine transgression during the early Pliensbachian-early Toarcian is also interpreted here in a time scale based on ammonite faunas, giving a preliminary temporal reconstruction of the entire Chubut Basin. Keywords: Invertebrates, La Casilda, Mulanguiñeu Formation, Chubut Basin, Argentina.
