# Northwest Upstate Illini Conference

The Northwest Upstate Illini Conference is a high school conference in northwest and north central Illinois. The conference participates in athletics and activities in the Illinois High School Association. The conference comprises 21 small public high schools with enrollments between 60-340 students in Carroll, Jo Daviess, Lee, Ogle, Stephenson, Whiteside, and Winnebago counties.

## History

In 1996 the Northwestern Illinois Conference (NWIC) and Upstate Illini Conference (UIC) merged under the Upstate Illini banner. Initially three divisions were formed for all team sports except football: West - Dakota, East Dubuque, Galena, Lena-Winslow, Orangeville, River Ridge, Stockton, and Warren East - Ashton-Franklin Center, Durand, Kirkland-Hiawatha, North Boone, Pecatonica, Rockford Lutheran and South Beloit, and South - Forreston, Freeport Aquin, Fulton Unity Christian, Eastland, Pearl City, Milledgeville, Mt. Carroll and Polo. In 1999 Savanna was added to the South Division and Rockford Christian Life to the East Division for a total of 24 teams. In 2000, after six schools (Ashton-Franklin Center, Durand, Kirkland-Hiawatha, North Boone, Pecatonica and South Beloit) left to form the Four Rivers Conference, the two remaining schools from the East, Rockford Christian Life and Rockford Lutheran, also left the conference looking for competition within closer proximity.
Based on all of these changes, the remaining schools realigned under the new moniker '"Northwest Upstate Illini"' starting with the 2001 school year. The 18 remaining schools maintained divisional balance in all sports for 4 years, however, during the 2004-05 school year, the school districts of Savanna, Mt. Carroll and Thomson consolidated into the West Carroll School District, becoming the largest high school in the conference. This consolidation reduced the teams in the Northwest Division of football to 6 and also created a scheduling issue due to an odd number of teams within the conference. To correct this, prior to the 2005-06 school year, four schools, Ashton-Franklin Center, Durand, Pecatonica, and South Beloit, joined the conference. These four schools were previously members of the Four Rivers Conference and raised the number of schools from 17 to its highest total of 21. Fulton Unity left the conference to join the Northern Illinois Christian Conference after the 2007 school year, reducing the conference to a total of 20.
South Beloit left the NUIC after the 2015-16 season. The Sobos joined the Northeastern Athletic Conference to compete against schools from Chicago, Rockford, Aurora, Arlington Heights, Elgin, Hebron, Crystal Lake, Ottawa, Mooseheart and Kirkland. To replace the exiting team, the NUIC added Amboy High School, formerly a member of the Three Rivers Conference. The Clippers began competition in the NUIC during the 2016-17 school year.
Between 2019 and 2020, seven teams within the conference announced that they would begin playing 8-man football. This change, as well as several schools cooping, reduced the number of 11-man football teams to nine. In order to maintain competitive balance, Fulton High School joined the NUIC for the 2021-22 school year from the Three Rivers Conference. A member of the Three Rivers Conference since the league's inception in 1975, Fulton made the move to the Northwest Upstate Illini Conference prior to the 2021-22 school year. The addition of Fulton brought the total number of schools back to 21. The Morrison Mustangs joined the NUIC starting in 2024, also leaving the Three Rivers Conference. This addition reunites Fulton and Morrison in the Battle for the Wooden Shoe, a rivalry game that began in 1977 and was halted in 2021 after Fulton left the conference. The addition of Morrison took the total number of schools in the conference to its highest total, 22. However, due to drastic decline in enrollment, Aquin Catholic High School closed in May 2024 reverting the total number of schools back to 21.

## Divisions and alignments
### Basketball divisions

In 2001, as the conference realigned under its new label, the divisions were broken into 2; nine team divisions.
Those groups were:
* North - Dakota, East Dubuque, Galena, Lena-Winslow, Orangeville, River Ridge, Scales Mound, Stockton, and Warren
* South - Aquin, Eastland, Forreston, Fulton Unity, Milledgeville, Pearl City, Polo, Savanna, Mt. Carroll
Starting in 2005, after the addition of the teams from the Four Rivers Conference and the unification of Savanna, Mt. Carroll and Thomson into West Carroll, the league broke into three divisions for basketball. Each division had 7 teams, however, for girls basketball, River Ridge and Scales Mound formed a coop that would keep the West with only 6 teams.
Those groups were:
* North - Aquin, Dakota, Durand, Orangeville, Pearl City, Pecatonica and South Beloit.
* South - Ashton-Franklin Center, Eastland, Forreston, Fulton Unity, Milledgeville, Polo, and West Carroll.
* West - East Dubuque, Galena, Lena-Winslow, River Ridge, Scales Mound, Stockton, and Warren.
This three division system lasted only for two years when Fulton Unity Christian joined the North Illinois Christian Conference for basketball prior to the start of in 2007-2008 school year. The league realigned back into two divisions with each having 10 teams. These divisions remained constant with the only change occurring in 2016 when Amboy was added to the East to replace South Beloit after their departure.
These groups were:
* East - Amboy, Aquin, Ashton-Franklin Center, Dakota, Durand, Forreston, Milledgeville, Orangeville, Pecatonica, and Polo.
* West - East Dubuque, Eastland, Galena, Lena-Winslow, Pearl City, River Ridge, Scales Mound, Stockton, Warren and West Carroll.
Prior to the 2019-2020 school year, the conference realigned back to three divisions. The divisions would be labeled North, South and West and would be unbalanced with two divisions having 7 teams and one having 6. Fulton joined the conference for the 2021-22 season and were placed in the South Division, giving each division 7 teams. Prior to the 2023-24 season, Orangeville and Aquin boys basketball began a coop, reducing the number of teams in the North to 6.
These divisions were:
* North - Dakota, Durand, Lena-Winslow, Orangeville/Aquin (coop), Pearl City, and Pecatonica
* South - Amboy, Ashton-Franklin Center, Eastland, Forreston, Fulton, Milledgeville, and Polo
* West - East Dubuque, Galena, River Ridge, Scales Mound, Stockton, Warren, and West Carroll
2024 Realignment:
Morrison's entrance into the league and Aquin's departure created an imbalance that required an adjustment in order to maintain equal numbers for each division. In the North, the Orangeville/Aquin coop was eliminated and Forreston was moved from the South to put the total number of teams at 7. The addition of Morrison to the South division kept the total number of teams at 7 with the West being untouched and also keeping 7 teams total.
These divisions are:
* North - Dakota, Durand, Forreston, Lena-Winslow, Orangeville, Pearl City, and Pecatonica
* South - Amboy, Ashton-Franklin Center, Eastland, Fulton, Milledgeville, Morrison, and Polo
* West - East Dubuque, Galena, River Ridge, Scales Mound, Stockton, Warren, and West Carroll

### Football alignment

Initially in 2001, the Northwest Upstate Illini was divided into two football divisions, each having 7 total teams. These divisions were:
* Northwest - Dakota, Eastland-Pearl City (coop), Forreston, Galena, Lena-Winslow, Mt. Carroll and Savanna
* Upstate - Aquin, East Dubuque, Milledgeville, Orangeville, Polo, Warren-River Ridge (coop), and Stockton
In 2005, Mt. Carroll and Savanna consolidated with Thomson to become West Carroll. During the same year, four teams from the Four Rivers Conference (Ashton-Franklin Center, Durand, Pecatonica, South Beloit) were accepted to join the conference. Durand, Pecatonica and South Beloit joined the Northwest Division and Ashton-Franklin Center entered the Upstate. In 2016, upon the departure of South Beloit, Amboy took their position in the Northwest division.
The final alignment of these divisions were:
* Northwest - Amboy-LaMoille-Ohio (coop), Dakota, Durand-Pecatonica (coop), East Dubuque, Eastland-Pearl City (coop), Forreston, Galena, Lena-Winslow, West Carroll
* Upstate - Aquin, Ashton-Franklin Center, Milledgeville, Orangeville, Polo, River Ridge, Stockton, and Warren
Starting in 2019, Polo and River Ridge ceased playing traditional 11-man football and began playing 8-man. This change, along with Warren forming a coop with Black Hawk High School in South Wayne, Wisconsin, has created a conference realignment specifically for football. The conference split geographically into North and South divisions with seven schools on each side. Crossover games between schools in different divisions were scheduled based on enrollment.
These divisions were:
* North Division - Dakota, Durand-Pecatonica (coop), East Dubuque, Galena, Lena-Winslow, Orangeville, Stockton
* South Division - AFC, Amboy-LaMoille-Ohio (coop), Aquin, Eastland-Pearl City (coop), Forreston, Milledgeville, and West Carroll
In 2021, five more teams from the conference transitioned to 8-man football. These teams include Ashton-Franklin Center, and Milledgeville as well as the 1984 (2A) state champion Amboy, the 1989 (1A) state championship team Orangeville, and Freeport Aquin, who claimed the (1A) state championship in 1981, 1986 and 2005. However, with the 2022 addition of Fulton High School, the conference has a net loss of only four teams. These changes will reduce the number of 11-man teams to 10 teams and eliminate the need for divisional play. The 2022 season included:
* 11-Man Football - Dakota, Durand-Pecatonica (coop), East Dubuque, Eastland-Pearl City (coop), Forreston, Fulton, Galena, Lena-Winslow, Stockton and West Carroll
* 8-Man Football - Amboy-LaMoille-Ohio (coop), Ashton-Franklin Center, Aquin, Milledgeville, Orangeville, Polo, and River Ridge
On November 18, 2021, the East Dubuque board of education voted 5 to 1 in favor of joining Southwestern High School (Wisconsin) for football, leaving the NUIC and bringing the total number of teams competing in 11-man football down to nine. This reduction causes each team in the conference the need to seek a non-conference game each season. The 2023 season included the following alignment:
* 11-Man Football - Dakota, Durand-Pecatonica (coop), Eastland-Pearl City (coop), Forreston, Fulton, Galena, Lena-Winslow, Stockton and West Carroll
* 8-Man Football - • North 1 Division: Ashton-Franklin Center •North 2 Division: Amboy-LaMoille-Ohio (coop), Aquin, Milledgeville, Orangeville, Polo, and River Ridge
The 2024 season creates a change in the structure of NUIC football. Regarding 11-man, Morrison joins the league with 2A state championships in 2009 and 2011. The total number of 11-man schools, however, remain at 9 due to the fact that West Carroll converts to 8-man. An additional change in 8-man includes Aquin closing and no longer competing.
The 2024 season included the following alignment:
* 11-Man Football - Dakota, Durand-Pecatonica (coop), Eastland-Pearl City (coop), Forreston, Fulton, Galena, Lena-Winslow, Morrison, and Stockton
* 8-Man Football - • North Division: Amboy-LaMoille-Ohio (coop), Ashton-Franklin Center Milledgeville, Orangeville, Polo, River Ridge, and West Carroll

### Volleyball alignment

In 2001, the conference utilized the same concept of North and South divisions for girls volleyball.
Those groups were:
* North - Dakota, East Dubuque, Eastland, Galena, Lena-Winslow, Orangeville, River Ridge, Scales Mound, Stockton, and Warren
* South - Aquin, Forreston, Fulton Unity, Milledgeville, Mt. Carroll, Pearl City, Polo and Savanna
Similar to basketball, when the league expanded in 2005, some teams shifted and the arrangements moved to the following 3 division system:
* North - Aquin, Dakota, Durand, Orangeville, Pearl City, Pecatonica and South Beloit.
* South - Ashton-Franklin Center, Eastland, Forreston, Fulton Unity, Milledgeville, Polo, and West Carroll.
* West - East Dubuque, Galena, Lena-Winslow, River Ridge, Scales Mound, Stockton, and Warren.
In 2014, the conference eliminated divisions and created a single volleyball conference with all 20 teams and South Beloit was replaced with Amboy after they left the conference in 2016.
Prior to the 2019-2020 school year, the conference realigned back to three divisions. The divisions would once again be labeled North, South and West and would be unbalanced with two divisions having 7 teams and one having 6, however, this alignment changed for the 2021-22 season as Fulton joinied the South Division, giving each division 7 teams.
These divisions were:
* North - Aquin, Dakota, Durand, Lena-Winslow, Orangeville, Pearl City, and Pecatonica
* South - Amboy, Ashton-Franklin Center, Eastland, Forreston, Fulton, Milledgeville, and Polo
* West - East Dubuque, Galena, River Ridge, Scales Mound, Stockton, and Warren, and West Carroll
2024 Realignment:
Morrison's entrance into the league and Aquin's departure created an imbalance that required an adjustment in order to maintain equal numbers for each division. In the North, Forreston was moved from the South to put the total number of teams at 7. The addition of Morrison to the South division kept the total number of teams at 7 with the West being untouched and also keeping 7 teams total.
These divisions are:
* North - Dakota, Durand, Forreston, Lena-Winslow, Orangeville, Pearl City, and Pecatonica
* South - Amboy, Ashton-Franklin Center, Eastland, Fulton, Milledgeville, Morrison, and Polo
* West - East Dubuque, Galena, River Ridge, Scales Mound, Stockton, Warren, and West Carroll
