On May 9, 2015, voters within Montgomery ISD's attendance zone voted in favor of a $256.75 million bond. The bond package included the construction of three schools: a high school, middle school and elementary school. The new high school was included to reduce enrollment at the district's other high school, Montgomery High School, whose student population had risen beyond the school's capacity. Board members decided to name the new school after the Lake Creek Settlement, the first Anglo-American settlement in Montgomery County. The district conducted a survey of future students to determine the school's mascot and colors. The school opened in August 2018 at a cost of $98.28 million. For the 2018-2019 academic year, the school opened with around 900 students in 9th, 10th, and 11th grades. The school fully incorporated seniors in the 2019-2020 academic year. The school was closed from March 11 to May 4, 2020 over fears of the coronavirus pandemic.
Demographics
As of the 2018–2019 school year, LCHS had 914 students enrolled.
22.2% of students were eligible for free or reduced-price lunch.
Academics
In accordance with House bill 5 of the 83rd Texas Legislature, Lake Creek High School offers instruction in "core foundation" subjects and "endorsement pathways." Foundation courses include traditional subjects such as English, math, science, and social studies. Originally, to fulfill the foreign language requirement, students could take either Spanish or French. After just one year, the school discontinued the French program, leaving only one language for students to take. HB5 designates four "endorsement pathways" that students may follow: Arts and Humanities, Business and Industry, Public Service and STEM. For Arts and Humanities, students at Lake Creek High School may take courses such as art, band, choir, dance, debate, journalism and theater arts. For Business and Industry, the school offers courses in agriculture, business, information technology and manufacturing. For Public Service, students may take courses in education, health science, fashion and law enforcement. For STEM, students make take courses in engineering or computer science. For the 2018-2019 school year, it was given an A rating by the Texas Education Agency.
Sports
The school offers competitive athletics in the following sports: American football, volleyball, basketball, soccer, baseball, softball, track, cross country, swimming, tennis and golf. Female students may also participate in cheerleading and the "Royals" dance team.
After an inaugural season with one win, Lake Creek's boys' soccer team was restructured.
Campus
Lake Creek High School has six athletic fields and a 996-seat auditorium. In March 2018 an area resident asked the district to construct a sound barrier so his house would get less noise from air conditioners used for the school.
Attendance and feeder patterns
At opening, all sophomores and juniors at Montgomery High School were allowed to choose which high school they attended through an "intra-district transfer". This policy was walked back in 2019 by the school board. As Assistant Superintendent Duane McFadden explained, "You don't get to choose what school you go to." The following elementary schools feed into Lake Creek High School:
