DNR fisheries survey

Minnesota DNR's Standard Survey on June 28, 2004 caught 9.25 northern pike per gill net at Hope Lake. Length samples in the latest survey that recorded them ran 19–31 inches.

A DNR fisheries survey reports fish abundance and catch rates, not water quality. LakeQuality shows Hope Lake’s water-quality measurements separately, and the water-quality trend over 3 years of monitoring is declining. Catch rate is not a swim clearance and is not a weekly bite report.

From the 2004-06-28 survey

Gill nets, trap nets and shoreline seining were used to sample the Hope Lake fish population during the 2004 summer. Aquatic plant sampling and water quality monitoring were also conducted. Hope Lake has a history of winterkill, and fish population levels can fluctuate greatly depending on the frequency and severity…
