These wetlands are generally Typo 1 <br /> <br />(Cirs",lar aQ) sr PEM (Palustrine Emergent). The project may result in loss or reduction <br /> <br />in size of irrigation induced wetlands in irrigated fields. Estimated average of wetlands <br /> <br />in the watershed are: <br /> <br />Type I, II, III <br />Type V, VI <br /> <br />3,000 Acres (PEM) <br />12,000 Acres (POW, PFO, R20W, R40W) <br /> <br />Wetlands were digitized usina GRASS version 4.2.
