Hydrology/Water Quality. Increased delivery and irrigation efficiencies (Completed and Sustained) • With funding provided by the Pacific States Marine Fisheries Commission under a grant from NMFS, in cooperation with CDFW, undertook an irrigation efficiency study. • Cooperated in more than seven years of CDFW studies of juvenile salmonid distribution and habitat use with direct observations, PIT tag technology, water temperature monitoring, flow monitoring, etc. • Replaced 500 feet of open ditch with pipe on the Gravity Ditch. • Repaired concrete lining on 1500 feet of main Pump Diversion, Main Ditch, 2013. • Upgraded irrigation turnouts on 300-400 feet of Pump Diversion, Alyssa Field Ditch, 2013. • Manage, currently and for the foreseeable future, diversion of Appropriative Water Right for “Clear Spring” to protect water quality for instream habitat. Spring flow may fluctuate annually, seasonally and diurnally, so full right of 2.5 cfs is generally not diverted to accommodate the variability, thereby improving stream temperatures below the Pump Station POD and increasing volume of the summer rearing habitat for juvenile salmonids, especially 0+ coho and steelhead. • Permittee agrees to maintain concrete lining on main delivery ditch of Pump Diversion. • Permittee is cooperating with UCCE to experiment with the use of soil moisture sensors and related technology to optimize applied water, which may result in a reduction of diversion and, ideally, improved instream water quality. Tailwater Reduction (Completed and Sustained) • Since 2009, Permittee modified practices on Gravity Ditch to irrigate short and/or steep pastures, which require more frequent changes, during the day. The more distant, flatter, and longer pastures are irrigated at night. • Permittee repaired and/or established tailwater berms at the low side of irrigated pastures. • Permittee agrees to continue and refine irrigation practices that minimize applied water accumulating at the low side of fields. • Permittee agrees to maintain tailwater berms and continue irrigation practices that reduce to insignificant or eliminate tailwater returning as warm surface flow to perennial streams. Participation in reach-wide Diversion Management Plan (Completed) • Participated in July, 2015 flow/diversion experiment in the upper Shasta River to evaluate alternative diversion coordination scenarios. • Participated in MWCD pulse flow/environmental water release experiments with access for monitoring. • Cooperated in XxXxxx and Xxxx...

Hydrology/Water Quality. Increased delivery and irrigation efficiencies (Completed and Sustained) With funding provided by the Pacific States Marine Fisheries Commission under a grant from NOAA in cooperation with CDFW, undertook and irrigation efficiency study. Cooperated in more than seven years of CDFW studies of juvenile salmonid distribution and habitat use with direct observations, PIT tag technology, water temperature and flow monitoring, etc. Permittee has completed project to design and construct a spring source management structure at the head of Kettle Springs Creek, including replacing 2300 feet of open ditch with pipe and alfalfa valves. Permittee agrees to operate and maintain the Kettle Springs Irrigation Management Structure that by design leaves flow in excess of water right instream. Permittee is cooperating with UCCE to experiment with the use of soil moisture sensors and related technology to optimize applied water, which may result in a reduction of diversion and, ideally, improved instream water quality. Permittee agrees to implement modified irrigation practices if so informed by the findings of the research.
Hydrology/Water Quality. Increased delivery and irrigation efficiencies Assuming acquisition of additional funding for evaluation, design, permits, and construction, Permittee will reconstruct, operate, and maintain Parks #4 Diversion to supply irrigation to fields on both sides of Parks Creek (Figure 5). Fields on the east side of the creek are currently irrigated by diverting at Parks #1. Between ditch loss savings (of an undetermined quantity) and flow bypassed between Parks #1 and #4, stream habitat quality could benefit significantly, especially during the critical spring time-frame for smolt migration and juvenile Covered Species and steelhead redistribution. Critical riffles, for emigration of smolts and redistribution of fry, in and between the upper and middle reaches of Parks Creek lie between Parks #1 and Parks #4 PODs. There is currently only one diversion opportunity for eastside pastures in this vicinity, thus there are limited options for assuring both irrigation demand and fish passage requirements are met. With a project to reconstruct the diversion at the location of Parks #4 to supply irrigation water to both sides of the stream, as historically existed, flow could be bypassed at Parks #1 when water volume and temperature requirements are optimum for salmonid passage through the critical riffles. As flows and water quality diminish in late spring and early summer, typical of snowmelt streams such as Parks Creek, irrigation demand could be taken at either or both POD, mimicking seasonal change in instream aquatic conditions and responding to seasonal increases in crop and stock water demand. Time Frame: Within 5 years of permit issuance.
Hydrology/Water Quality. Increased delivery and irrigation efficiencies • With acquisition of sufficient matching funds, Permittee agrees to complete, operate, and maintain a Diversion Combining Project, which includes replacing up to 4000 feet of open, mostly earth-lined Gravity Ditch with pipe. Upon completion, seepage loss savings (estimated at 0.7 cfs) will be exchanged for an equal volume of Clear Spring water retained in-stream and not diverted. Time Frame: Underway; Completion Estimated within 5 years of ESP issuance. • In the interim, before completion of the Diversion Combining Project, Permittee agrees to collect further data to quantify ditch loss to be translated into efficiency savings with implementation of the completed Project. • Permittee will seek matching funds to and establish fences to create riparian pastures or exclusion fencing on Hole-in-the-Ground Creek. Time Frame: Within 5 years of ESP issuance. Tailwater Reduction • Permittee agrees to work cooperatively with neighboring landowners to solve issue of warm surface water, from source not on Permittee, entering Hole-in-the-Ground Creek near north property line. Time Frame: Within 5 years of ESP issuance. Soil Moisture Monitoring Program • See Section E.3.a., below. Participation in reach-wide Diversion Management Plans • See Section E.3.a., below. Upgrade/repair/maintain diversion facilities • Permittee agrees to continue participating in studies to redesign neighbor’s diversion (which is located at 122.44445W, 41.56325N; Xxxxxxx Diversion) and eliminate associated water quality issues. Participation includes providing access for personnel and equipment during design and construction, implementation monitoring, and effectiveness monitoring, and adjusting livestock management to accommodate project design, construction, monitoring, and post-construction changes in vegetation. Time Frame: Underway; Completion Estimated within 5 years of ESP issuance. • Also see Diversion Combining Project, described above in Section E.3.a., below. E.2.b Passage/Migration/ Diversion Screening Remediation of identified on-site barriers • Permittee agrees to continue cooperating in project to move Xxxxxxx Diversion, eliminate associated fish passage issues, and maintain fish passage at the new crossing.
