In total, 616 NP have been removed since mechanical suppression effort began in Boundary Reservoir in 2016. In 2020, a total of 30 nets were deployed and 26 Northern Pike removed between March 9 and March 12, with a final catch-per-unit-effort (CPUE) of 0.87 NP/net-night. The 2020 suppression effort was expected to run through April 30 but was suspended for the season due to the COVID19 pandemic. The Kalispel Natural Resources Department collected 28 Northern Pike during the 2020 Spring Pike Index Netting (SPIN) Survey conducted May 18 through May 20. The resulting CPUE of 0.93 NP/ net-night in sloughs and mainstem river between Box Canyon Dam and Metaline Falls. Although this was higher than ≤ 0.50 NP/net-night it fell within the 95% CI (0.43 to 1.43) meeting the abundance target for the reservoir.
