BOX 2004 ROCK ISLAND, ILLINOIS 61204-2004 REPLY TO ATTENTION OF http://www.mvr.usace.army.mil CEMVR-PM-M PEORIA RIVERFRONT DEVELOPMENT, ILLINOIS (ECOSYSTEM RESTORATION) FEASIBILITY STUDY WITH INTEGRATED ENVIRONMENTAL ASSESSMENT MAIN REPORT MARCH 2003 Executive Summary he Peoria Riverfront Development (Ecosystem Restoration) Project area includes Lower Peoria Lake. The area lies within Peoria and Tazewell Counties, Illinois, and includes TIllinois River Miles 162-167. The project is related to the Peoria Riverfront Development Project, a public and private cooperative effort that also includes revitalization of the City’s downtown area. Development includes a visitor’s center, city park, residential redevelopment, community center, riverboat landing, sports complex, entertainment centers, and retail development. The region has begun to reclaim its abandoned industrial riverfront, with the understanding that a healthy, attractive, and sustainable environment must be present. The Illinois River is a symbol of the region’s economic, social, and cultural history, as well as its future. Therefore, ecosystem restoration in Peoria Lake is a vital component to an overall effort and vision to develop the Peoria Riverfront in an ecologically, economically, and socially sustainable manner. This Ecosystem Restoration Feasibility Study was conducted by the U.S. Army Corps of Engineers and the Illinois Department of Natural Resources (Non-Federal Sponsor) to investigate the Federal and State interest in ecosystem restoration within Peoria Lake. In support of this resource vision, several regulatory efforts on the part of the cities and counties to address the sedimentation issue affecting the Illinois River have been adopted.

Green sunfish are not as deep bodied as other commonly known sunfish, and typically have a more Green sunfish in the wild: drab color scheme. They have a blue-green back that fades to http://www.bobberstop.com/images/gr yellow or white at the belly, and have a black earflap with a een_sunfish.jpg yellow edge (see drawing). Green sunfish have a top jaw that extends back to the middle of the eye, and a mouth that is larger than its close relatives. Unfortunately, green sunfish may hybridize with pumpkinseed and bluegill sunfish (see photo to left), making identification difficult. Sunfish identification becomes difficult when hybridization occurs: http://www.southernpondsandwildlife.c om/upload/articletitles/000052.50.jpg Small green sunfish before release back to the water: http://www.tnfish.org/PhotoGalleryFish_TWRA/FishPhotoGallery_ TWRA/pages/GreenSunfishMeltonHillNegus_jpg.htm Green sunfish do not favor any bottom type in Oneida Lake, but generally live near brush, vegetation, and rocks. Unlike most sunfish, greens tolerate areas with high turbidity and Line drawing of a green sunfish low dissolved oxygen. In Oneida, green sunfish eat small fish, aquatic insects, and other invertebrates, and their large mouths allow them to eat larger prey than other sunfish can.

It has endured in the face of the changing times, without itself changing much, isolated off in its own world. Glorfindel had the opinion that Bombadil would be the last to fall, after all else was lost, last as he was first. In Tolkien’s story, that opinion was never tested. Good triumphed over evil, and everyone lived happily ever after. Not true on the Internet. Since 1993, the forces of evil have created a desolation and oppression that Sauron even with the help of his ruling ring could not imagine perpetrating. From the days of the Internet as an academic research network until today’s Internet I have witnessed ruination unbelieveable. The decay, corruption, and runiation of the Internet boggles my mind. Like Tom Bombadil in his carefully demarcated borders, The Genesis Discography has been an island in the storm, surrounded on all sides but never giving in.

  • EARTH, WIND & FIRE -‐ Bio XRIJF JUNE 20-‐28, 2014 During the 1970S
    EARTH, WIND & FIRE - Bio During the 1970s, a new brand of pop music was born - one that was steeped in African and African- American styles - particularly jazz and R&B but appealed to a broader cross-section of the listening public. As founder and leader of the band Earth, Wind & Fire, Maurice White not only embraced but also helped bring about this evolution of pop, which bridged the gap that has often separated the musical tastes of black and white America. It certainly was successful, as EWF combined high-caliber musicianship, wide-ranging musical genre eclecticism, and '70s multicultural spiritualism. "I wanted to do something that hadn't been done before," Maurice explains. "Although we were basically jazz musicians, we played soul, funk, gospel, blues, jazz, rock and dance music...which somehow ended up becoming pop. We were coming out of a decade of experimentation, mind expansion and cosmic awareness. I wanted our music to convey messages of universal love and harmony without force- feeding listeners' spiritual content." Maurice was born December 19, 1941, in Memphis, TN. He was immersed in a rich musical culture that spanned the boundaries between jazz, gospel, R&B, blues and early rock. All of these styles played a role in the development of Maurice's musical identity. At age six, he began singing in his church's gospel choir but soon his interest turned to percussion. He began working gigs as a drummer while still in high school. His first professional performance was with Booker T. Jones, who eventually achieved stardom as Booker T and the MGs.
