Y w J. 4a +,'I, i:! � t 15 F . nB Currently, a revised hydrologIc model is being formulated for the Forks of Butte project. Due to the canplexi,ty of inter-basin water transfer and water diversions in lower Butte Creek, the USGS Station #✓:3897 at Butte leadcxws will be the sole source of hydrologic data in this new analysis. :results will be sent to the CDFG when the analysis is completed. Significant deviations from the initial study, ?txwevex, are not anticipated. D. Fishery Resources; Butte Creek has been periodically surveyed by CDFG, Unitr-.d States Fish x and Wildlife Service, Bureau of Lid Management, and Pacific Gas and Electric , Company personnel. The existing infortration base, therefore, is' fairly comprehensive. Estimated rout production upstream of. the Butte Creek Diversion Dam in Butte 'Meadows is 2,500 trout/mire (Flint and Meyer 1977). Irm*ediately, downstream of the Butte Creek Diversion Dam, brown .and rainbow trout production decreases to 50 trout/mile, Aquatic condi tions improve in the propssed project area due to the water input from the West Branch of Butte Creek; estimate, trout production is 200 fish/mile in ttze proposed project r(Flint and N�yer 1971). Since trout production is much greater in meadow habitat than in canyon habitat (Gerstung 1973) j, it is not known for certain whether the 200 fish/mile is a reduced production level due to the decreased flows. it is evident, however, that the extremely law sutr►rer flows M indiatF.I.y below Butte Creek Diversion Dam limits trout production in this area. pulation 'data were collected, Baseline nozg hr the LicenApplication i8epteVber and October, 983 utilizing electrosockinc and snorkeling techniques, respectively;. Electroshocking was employed in the upper,project area at the proposed diversion site. population estimates were conducted at seven 100-foot sections using the Moran"Zippen method (Moran 1951; Zippen 1956). Blocknets were placed at each end of the sections. Fish were caught with a direct-current electroshocker during three successive passes without intervals between fishing runs. )Each pass was timed to assure equal g. nets was sampled. Due to =Lxcessive pool. depth, el ctroshocklix � could only be conducted in riffle and run habitat types. Electroshocking settings were as follows: pulse width, 6.0 milliseconds; frequency, 80 hertz; and output voltage, 450 volts Caught fish were anesthetized with MS-222 (tricain methane sulfonate) mid measured (total length) to the nearest millimeter (mm) Rainbow trout (Salem gairdneri) was the only fish spedies sampled Means of eight yearling or older fish and fifteen fry were estimated for each 100-foot stream section.. These values reflect population densities in riffle and: rw habitat types only. The largest trout sampled was thirteen inches in length. 1968; Griffith 1972; Bustard and Narver 1975; Dunn 1981). .Approximately one-third of the stream reach from the proposed diversion site to, the proposed powerhouse- was surveyed; an approximate one-hiuzdred-foot section of stream was surveyed every three -hundred feet throuc-h the entire project area. Over 1 000�fish were observed and only rain; present , rainbow trout were throughout the project area. One-hUftdred--foot sections of pool habitat contained an average of 2 fry, 5 trout Vin- to 7" -long, 3 trout 811- to 12" -long, and 2 trout 13'"- to 18"-1"ong. Alla of the larger, fish were observed. in pools. Rainbow 'trout population es0�amates in riffle and run hahita s were similar to those obtained by electroshocki.ng. While some large tvout occupied each pool., rainbow trout population densities and production levels were relatively low. Nate summer and fall habitat conditions arm degraded annually due to dredging activities and upstream water diversions during this period. While brown trout (Salmw tr.ttta) are present in Upper Butte Creek in meadow habitat, this species was not detected in the project:t area, The steep, canyon habitat is more conducive to :rainbow trout inhabitancei and the heavily salted substrate may also restrict brown trout occurrence in the project area. Spawning gravels are highly degraded in the fall due to siltation and would significarntly reduce brown trout eggs embryo, and alevin survival raises. mow trout- are not impacted as they spawn in spring subsequent to high` flushing flows. r «'bile an extremely small number of brown trout may exist in the project area, this r - one pe total trout population arid, therefoe, rather insignificant. Hber is less istorically, scent of the wizzterTiste�tead trouti(SaLno Gook salmon (Oncorh chus tshawytscha) and "g ' dneri) may have migrated itito the proposed 'project area to spawn, but dams and water diversions in lower' But to creek have eliminated access into the project area.

Habitat loss caused by the proposed y L� project during the critical low=flow summer Period and duringandroughts would be zero since the project would not operate. At discharges between 58 and 270 cfs, the `project would divert up to 250 cfs and b ypa.ss the minimum required flow, assumed to be 20 cfs in this case. Fry habitat appears to be 'invited at all flaws greater than 10 cfs. This project will enhance f %spg fry stat, therefore, when natural flows are between 57 and 270 cfs by providix:,� near optimum fry habitat conditions. ,Tuvenile habitat at 20 cfs is reduced only 4 percentfrom optimum habitat conditions ` Cat 26 cfs) , but is currently reduced approximately 20 to 41 percent when flows are between 57 and 200 ofs (gable 5). While adult habitat n at 20 cfs reduced 36 percent fresh optimum conditions occurring at 47 cfs, natural Heats greater than .100 cfs, which. occur from December through May, decrease habitat, over 37 percent. Flushing flows have been found to be necessary ravel � �'` for stream ch��nnel and.: g quality maintenance (Mz.lhouse and Bovee 1977), Significant reductions of peak flaws can cause sedimentation problems as the size of substrate { material that can be transported through the system i Unfortunately, there s reduced: is currently no methodology for recommending flushing flaws (Wesche and Rechard 1980). Based on 53 years of data from1923-1980 (5 . years, missing)th at e Butte Creek Diversion Dam, and adding downstream accretion derived from area -precipitation products, the estimated annual mean daily flow at; the proposed diversion site is 1.,550 cfs. The range is from 248 to 5,055 cfs with two-thirds of tlae peals flows occurring � n January, February, or March. With a maximum diversion capacity of 250 cfs, 5 to 100 percent of mean daily pew flayscould be diverted, It should. be pointed nut; however, that hourly peals discharges may be -two to three times greater than mean daily peOk discharges. proposed reduces annual g The p° project probably Peak discharges approximatel ten P should not have adverse effects; the peak flow reductions most malears and normal peals flow variability from year to year, and there are no tri, Oita es wiin thin the project area which will substantially increase silt loads into Butte Creek.

The two-hour period without diversion exceeds the tr"Vel time through the project area; travel time equals 1.25 4 hours assuming a mean water'veloci of three feet . ;�S' per second. ;This method, as with an flushing flow determinations, requires the ability to predict Y g ta:n�»of—concentration. There are many models available, however, which can be used for time,"of- concentration predictions (Snyder ,1972). This 1938; Taylor and Schwarz Carter 1951; U.S. Soil Conservation Serve plan should Se beI larien{sed in January or February,when high daily discharges g Y are most likely to occur: Gravel recruitment through the project area and flushing of fine sediments frcan spawning gravels using tlu.s methodology will prevent impacts to fishery resources from sed,•imntation. An automatic Tainter gate, a crest gate for passage of large flows, wall implemented to sluice bedload at high flows.. This gate will automatically open When a specified discharge is reached. Exact specifications will. be er, nined in. consultation with the CDFG. It is expected, however, that the gate will be designed, fxsuch a ate assures. that three or four times a year. gned Eo open appro�. mate g t bedload material moves past the diversion site at high flows when laedl.oad material is naturally moving in the y system. It can be concluded that *,w.i.tl a minim= 3stream flow r . equzremen•t of 20 cfs, there will be no reduction in usable habitat from project•cperatiori greater than reductions in usable habitat which occur at~ present during, natural- stxeamflOws. While the timing of certain discharges in Butte Creek Will be altered, habitat conditions will not be adversely impac ett. The summer low --flow period which determinesfish population levels in Butts' Creels w will not be affected by the proposed project; in the case of Butte Creek, the timing ox: water diversion is much more important than the quantity of water diversion. If the :Pacific Gas and Electric Company and CDFG agree to a 16 Js cfs bypass flow, the Forks of Butte project may increase trout production by increasing available habitat during the winter and spring. If no agreement is reached, the lay sunrer flows will continue to determine trout production in the project area, and increases in fish habitat resulting from the Forks of Butte project will not be utilized. By impI. lementing proposed mitigation measures for adequate flushing flaws, no impacts from sedimitation, channel morphology changes, or loss of downstream gravel recruitment will occur., V.

These conditions would require the Licensee to (1) errrd-haul all excavated material from slopes greater. than 50 percent tc BLM-approved disposal sites; (2) seed, fertilize, and mulch all disturbed areas as part of a vegetation plan. to meet BLM' approval; (3) complete detailed subsurface exploration in any areas with historic or potential slope instability, prior to BLM approval of the location of project facilities; (4) provide mitigation for disruption of theexisting Butte Creek Trail, to include the roaair, relocation, and constructian of now, sections o trail, as structures on public land to approved by BLM, (5) paint allprojectgs; G) locate structures to take atural blend with the nsurroundings,,; advantage of natural topographic and vegetative screening and use natural materials, where,applicable, to blend with the landscape$ (7) contour ekcav+atjons to blendwith undisturbed areas, as approved by BLM; and (8) provide a minimum bypass flow at the diversion structure of 47 cies or the existing streamflow, whichever is less, to protect fishery values. 2:/ C.

The failure of revegetation in the area is generally due to thin soils, steep slopes, and increased runoff. Failure of revegetation along the conduit route would, in turn, - adversely effect the terrestrial vegetation downhill, because of sedimentation and increased runoff, for potentially 3.5 miles.' The value of the canyon for edu,-Wati.onalpurposes, in the fields of plant taxonomy and ecology, wo-ld be degraded. This would be perceived as a significant impact by instructors, students, and nature enthusiasts. 9 The rare plant surveydid not encounter any populations of Brewer's rock cress along the proposed pipeline route. Although some inaccessable areas were not surveyed, the Applicant has proposed to conduct an additional. botanical survey of the specific pipeline route prior to construction and tc,� ,-.lag and avoid anypopulations of brewer's' rock cress that may be encountered' (80JC, 1983) zt is unlikely, therefore, that any, popul��tions of Brewer's rock cress would be removed by construction. The only potential impact to Brewer's rock cress would be burial from any Worst case situation involving severe erosion of disturbed surfaces uphill. one colony was mapped at a lower elevation than the conduit, in an area south of the suspension bridge, and would be vulnerable to erosion. Because .Four known locations of the species would not be affected, potential loss f the one colony below the conduit would not eliminate t minatethe majority of the )mown populations of Brewer's rack cress in the canyon and, therefore, would not significantly jeopardize the continued existence of the species. PlaceMeht of excavated 'al on disposal. sites A and 8 would not affect Brewer's rockmaterial Neiher disposal site contains the apps priate habitat for this species 1BCICt 1.983), Placement of excavated MaLerial on Site A would remove 1,5 acres of disturbed open scrub vegetation and diggerpine. Disposal at site 8 woutd remove 1.5 acres of disturbed oak -woodland. These acreage losses would not be signi Eicant. Revegetation of these disposal areas would be difficult, however, becnuse of the harsh tidge-top environment. The Applicant proposes to revegetate with native species, which are adapted to the area, and to mulch the disposal sites to prevent eros oh and to provide amore favorable environment for seedling establishment (anc, 1.983). Both disposal sites are on relatively minor slopes (15 percent), which should improve the prospects of erosion coLltrol.

According to Block et al. (1983) the existing riparian commut?ibi.es are maintained at early and maid -stages or ecc�logica.l succession because periodic flooding favors riparian species at the expense of upland: ,forest vegetation. periodic ncreases nutrient deposition, which is overbank flooding also i essential in Maintaining:riparian' vegetation (American Fisheries y Western Division, 1982) . By el.imi.nating periodic flaad`ing, � thepro,ect would reduce the competitive edge of the riparian species, a, low forest vegwtation to become established, displace p p grade the duality of the riparian corridor ecies, and de In' addaiti.o►i, continual low flows can -reduce the groundwatQr, flows Mester' t��visiiparia82) « (American F'ishi�r es Soc.�.et,�ry to ma�nta�.l, riparian, communities ye The Applicant proposes to p1 nt riparian tree ;species along the sureamside of the diversion access; 10/ and to provide flushing flows to maintain channel morpholag (BGIZ, 183). t�)a quantity (acreage or density of plantings) has been specified and the degree of necessary flushing flow releases have not been determined.
