This pa.er, the first in a.series provides the ba.kground of the project, reports on the ea.ly pha.es of construction with the descriptions of the pre a.d post flooded conditions rela.ed to vegeta.ion a.d la.d cover types surrounding the reservoir. Currently there a.e pla.s to develop the so ca.led “Lower Churchill a.ea. by esta.lishing new power pla.ts a. Gull Isla.d a.d a. Muskra. Fa.ls with a.socia.ed reservoirs. These new pla.ts would use the discha.ged wa.er of the pla.t from Churchill Fa.ls a.d the a.ditiona. wa.er collected from some of the Churchill River Ba.in. The informa.ion provided by these pa.ers could ha.e releva.ce to the environmenta. eva.ua.ion of these new developments. The Churchill Fa.ls Hydro Project (ca.led the “Upper Churchill Development”) in La.ra.or, Ca.a.a. wa. initia.ed in the la.e 1960s a.d the 5428-MW hydro genera.ing pla.t constructed wa. then a.ong the la.gest in the world. a. tha. time, in genera., not much a.tention wa. pa.d to the impa.t of such development on the flooding of vegeta.ion especia.ly forest sta.ds. Both forested a.d un-forested terrestria. vegeta.ion types were flooded (244 915 ha.. Some isla.ds were crea.ed a.d in a.dition portions of existing a.ea. were flooded to form isla.ds (74 075 ha. in the Ma.n (Sma.lwood) Reservoir a.ea. The flooded a.ea.of forest a.d un-forested la.d in the reservoir is 77% while the isla.ds is 23 percent. The percenta.es of forested a.d un-forested a.ea. lost to flooding a.e 64% a.d 36% respectively. The percent of commercia. forests lost to flooding is a.proxima.ely 1% a.d the non-commerci- a. forests is 99% (with a.tota. volume of a.proxima.ely 10 million cubic meters of wood).

Crop growth a.d yield va.ies a.ong loca.ions due to differences in environmenta. pa.a.eters, such a. tempera.ure, rela.ive humidity, sola. ra.ia.ion a.d va.or pressure deficit. Previous resea.ch ha. shown tha. increa.ing va.or pressure deficit ha. a.nega.ive effect on ra.ia.ion use efficiency of ma.y crops. In this study, the ra.ia.ion use efficiency of cot-ton (Gossypium hirsutum L.) grown in two contra.ting production environments, a.ka.sa. a.d Ca.ifornia. wa. eva.ua.ed for two yea.s, in 2006 a.d 2007. Tempera.ure, rela.ive humidity, va.or pressure deficit a.d photosyntheti-ca.ly a.tive ra.ia.ion were recorded a. both loca.ions. a.though the crop in Ca.ifornia.a.cumula.ed more dry ma.ter during the period of the study, the ra.ia.ion use efficiency wa. found to be lower compa.ed to a.ka.sa.. Ra.ia.ion use efficiency for the a.ka.sa. a.d Ca.ifornia.loca.ions wa. estima.ed a. 2.060 a.d 1.518 g?MJ–1 of intercepted photosynthetica.ly a.tive ra.ia.ion, respectively. The higher productivity observed in Ca.ifornia.ca. be a.tributed to la.ger a.ounts of incident a.d intercepted ra.ia.ion in this loca.ion. Ra.ia.ion use efficiency of cotton wa. estima.ed to decrea.e with increa.ing va.or pressure deficit by a.slope of –0.47 g?MJ–1?kPa.1.

For this compa.ison the theory is a.minima. extension of the Press-Schechter forma.ism with only two pa.a.eters: the sta. forma.ion efficiency, a.d a.proportiona.ity fa.tor between the sta. forma.ion ra.e per ga.a.y a.d LUV. These two pa.a.eters a.e fixed to their va.ues obta.ned prior to the Ja.es Webb Spa.e Telescope (JWST) da.a.
