Apprehensions surged 1,165% in one Border Patrol sector

Summary

Total apprehensions along the U.S.-Canada border rose 277% from fiscal 2019 to fiscal 2024, but nearly all of that growth came from a single place: Vermont's Swanton sector, where apprehensions rose 1,165% -- from 1,563 to 19,773 -- while the other seven northern-border sectors combined saw apprehensions fall. GAO's June 30, 2026 testimony found Border Patrol staffing didn't keep pace: even though authorized positions on the northern border grew 9% over that period, the number of agents actually on board fell 6%, pushing the northern border's staffing rate down from 90% to 78% -- below the 90% rate GAO found on the southwest border in fiscal 2024. The surveillance-monitoring staff are thinnest exactly where the surge hit hardest: Swanton's Law Enforcement Information Systems Specialist staffing rate, 57%, is the lowest of any northern-border sector, and a senior Border Patrol official told GAO the agency has no plan to improve it -- it expects those staff to leave for better opportunities. Vehicle incursions across the northern border rose 540% from fiscal 2021 to fiscal 2024. GAO's 2019 recommendations for northern-border-specific performance measures remain unimplemented; Border Patrol doesn't expect new measures until fiscal 2027.

Total Border Patrol apprehensions along the northern border rose 277% from fiscal 2019 to fiscal 2024, from 6,618 to 24,968, according to 's June 30, 2026 testimony. Almost none of that growth was spread evenly: it came overwhelmingly from one of Border Patrol's eight northern-border sectors.

One sector, nearly all of the surge

Vermont's Swanton sector went from 1,563 apprehensions in FY2019 to 19,773 in FY2024 -- a 1,165% increase that left it responsible for 79% of all northern-border apprehensions, up from 24% five years earlier. Blaine, on the Washington-British Columbia line, also grew sharply (+390%). Every other sector fell: apprehensions in the remaining six sectors combined dropped 49%, from 4,455 to 2,255.

Staffing didn't keep pace

Authorized Border Patrol positions on the northern border grew from 2,306 to 2,512 over the same five years, about 9%. But the number of agents actually on board fell from 2,073 to 1,948, about 6% -- pushing the northern border's staffing rate (on-board agents as a share of authorized positions) from 90% down to 78%. found the southwest border's staffing rate stood at 90% that same year. Air and Marine Operations agents near the northern border fell too, from 162 to 147, even as flight and float hours climbed.

The surge sector has the thinnest surveillance staffing

Northern-border sectors rely on Law Enforcement Information Systems Specialists to monitor camera towers and ground sensors; Border Patrol had filled 77% of those positions bureau-wide as of FY2024. Swanton's rate was 57% -- the lowest of any sector, in the sector seeing the most activity. A senior Border Patrol workforce-planning official told the agency has no plan to improve recruitment or retention for the position, and expects staff to leave for better opportunities. recommended a workforce plan in February 2026; agreed and estimates completion by January 2027.

More incursions, and old recommendations still pending

Reported vehicle incursions across the northern border rose from 48 in FY2021 to 307 in FY2024, up 540%. Meanwhile, 's 2019 recommendations that Border Patrol and AMO build performance measures specific to the northern border remain open: Border Patrol doesn't expect to implement new measures until fiscal year 2027, and is still gathering information on AMO's plan. has billions in new hiring money on the way -- $4.1 billion from the 2025 reconciliation law, plus $9.55 billion and over $13 billion more from the June 2026 Secure America Act -- but none of it is earmarked specifically for closing the northern border's staffing gap.

The takeaway

  • One sector explains almost the entire northern-border apprehension surge. Swanton, Vermont rose 1,165% (1,563 to 19,773) while the other seven sectors combined declined -- concentrating 79% of all northern-border apprehensions in one place, up from 24% in FY2019.
  • Staffing moved the wrong direction as the surge hit. On-board Border Patrol agents fell 6% even as authorized positions grew 9%, dropping the northern border's staffing rate from 90% to 78% -- 12 points below the southwest border's FY2024 rate.
  • The busiest sector has the weakest surveillance-monitoring staffing, and no plan to fix it. Swanton's 57% Law Enforcement Information Systems Specialist staffing rate is the lowest on the northern border; a senior official told the agency simply expects those staff to leave.
