... The Oregon fore-arc block extends from the Cascaclia subduction zone on the west to the Basin anti Range on the east. Its southern boundary occurs at the transition to the Sierra Nevada block, roughly in the vicinity of the California-Oregon border.
From page 49...
... The Shasta River watershed is at the junction between the Basin anti Range Province, in the Sierra Nevada block within the Cascaclia volcanic arc. Its watershed, which originates at Mount Ecicly, encompasses about 800 mi2.
From page 50...
... The watershed is locatecI entirely within the Cascaclia fore-arc region on the Sierra Nevada block. The high uplift rates ancI the lack of extensional tectonics have prevented the formation of any important alluvial valleys, such as those of the Scott ancI Shasta drainages.

... Unlike the upper basin, the lower Klamath basin exhibits two potential flow peaks, clepencling on the water year. Subtropical storms strike the Klamath watershed with high frequency from late December to early March anti are responsible for all peak ciaily discharges in the Klamath main stem anti its tributaries.

... Siltation causecI by agriculture ancI loss of wetiancI productivity has occurred in the last several clecacles, however, ancI waterfowl populations have cleclined (ILM 20001. Historically, suckers in Tule Lake ancI the Lost River were abundant enough to support cannery operations along the Lost River (USFWS 20011.
From page 56...
... To hoicI back flooc~waters from Tule Lake ancI store seasonal runoff for irrigation later in the season, a clam was constructed at Clear Lake in 1910, impounding the waters of the Lost River ancI creating a larger lake. Where Gerber Reservoir now stancis (Figure 1-3)

... Miners also reclucecI freshwater resources by overfishing, ciamming, anti diverting streams (Malouf ancI FincIlay 19861. The goicI rush brought extensive changes to the Scott River watershed, particularly the main stem anti South Fork anti Oro Fino, ShackleforcI, anti French creeks.
From page 61...
... Along the Salmon River, cluring the late 1800s anti into the 1990s, extensive placer goicI mining ancI some hyciraulic goicI mining were concluctecI in the main stem ancI the South ancI North Forks. The main stem of the Trinity River was severely impaired by placer mining within the channel ancI by hyciraulic mining ancI extensive cireciging.

... ancI Hamilton 19901. The cleleterious effects of mining on salmonicI habitat were so rapicI ancI intense that in 1852, only 4 yr after Sutter's discovery of goicI in the foothilis of the Sierra Nevada, California enacted its first salmon statute, which required "'all goocI citizens ancI officers of justice' to destroy man-macle obstructions to salmon migration, except those erected by Indians." That statute clicI little to stem habitat destruction.

... " Government inspectors who were sent to the region warnecI that overgrazing was ruining the very source of the region's prosperity. The inspectors recommenclecI that the only solution was to provide more grass by draining wetiancis ancI planting them with hay so that there wouicI be less competition for a c~wincIling resource (Griffiths 1902~.

... in some of the Sprague River watershed. Season-long grazing in the past probably contributed to recluction of spawning habitat for trout anc!
From page 66...
... In the lower I(lamath basin, timber harvesting began in the 1850s in the Scott River watershed commensurate with the growth in mining. As in most northern California watersheds, logging activity reachecI a peak in the 1950s (Sommerstram et al.
From page 67...
... The government wouicI then construct two new lakes to hoicI water for irrigation Behind Clear Lake ancI Gerber clams, Figure 1-31. A clam anti canal wouicI clivert the Lost River to the I(lamath River.

... It was to be one of the largest wilcIlife refuges ever authorized, one of the first on lancI of any agricultural value, anti the first to be establishecI in a watershecI being transformed by USBR. In 1911, President Taft establishecI the Clear Lake National Refuge ancI in 1928 President Coolicige establishecI Tule Lake National WilcIlife Refuge.

... In the Shasta River watershed, after the goicI rush in the late 1800s, most of the lancI cover of the Shasta Valley was converted for agriculture anti range. About 28% of the watershed is irrigable lancI that supports a mix of alfalfa, irrigated pasture, anti some grain (CDWR 19641.
From page 71...
... In the upper I(lamath basin, tribal harvests of suckers for family consumption were augmented by commercial harvests beginning in the 19th century, including a cannery that processed Lost River suckers captured from the Lost River near Olene, Oregon, in the late 1890s (53 Fed.
From page 72...
... The drop in cirainecI wetiancI acreage after 1990 reflects wetiancI restoration efforts in the upper basin. In Tule ancI Lower I(lamath lakes, original wetiancis were estimated at 187,000 acres; about 25,000 acres remain (Gearheart et al.
From page 73...
... A total of 17~553 acres of former wetiancis behind clikes is now being reclaimecI, but subsidence has meant that, even after being restored, these areas remain clisconnectecI from the lake ancI clo not function as the littoral wetiancis once clicI. Once clikes are removed, subsiclecI areas become open-water habitat rather than littoral wetiancis (Geiger 20011.
From page 74...
... It is cliviclecI into discussions of the upper anti lower basin economies, which differ substantially. Special attention is given to sectors of the economy oriented toward natural resources, inclucling agriculture in both the upper ancI lower basin ancI commercial fisheries in the lower basin.

... For example, the retail-trade sector's share of sectoral employment is 12.8%, and it provides just 3.8% of the export employment base. The lower basin's employment, like the upper basin's, depends heavily on income to households.
From page 89...
... The average annual pay per hirecI farm worker was $6~754. Thus, the number of farm workers in the lower basin is about one-thircI the number in the upper basin, but the average pay per worker is greater in the lower basin.
From page 91...
... Using the cletailecI multi-sector version of the Lower I(lamath Basin Input-Output Moclel, which is basecI on the 1998 IMPLAN moclel, to be consistent with the upper basin analysis, the effect of removing all the salmon catch in 2001 ($107,887) , assuming that the catch is exported from the region, is a total loss to the regional economy of $164,507.

... . In summary, the economics of the upper anti lower basins clisplay characteristics common to many rural economies, inclucling heavy reliance on natural resources sectors, such as agriculture ancI woocI products.
From page 93...
... Reliance on such sectors is slowly cleclining across both the upper ancI lower basins. OVERVIEW The I(lamath basin is exceptionally diverse geomorphically because it has been strongly influencecI by both crustal movement ancI volcanism.

... 94 FISHES IN THE KLAMATH RIVER BASIN continue to cause, severe physical impairment of aquatic habitats. Although aquatic habitats now are regarclecI as valuable for the maintenance of native species, remecliation of ciamage to habitat presents great clifficulties because of the extent anti diversity of changes that have occurred in the basin over the last century.
