Reverend Frederick Lagerman was pastor of the 1878 “Swedish Evangelical Congregation of Ryssby, Boulder County, Colorado” Lutheran Church. The church congregation purchased 160 acres of land near the current reservoir as a prastgard, or pastor’s garden. As was Swedish custom, church members farmed the land, giving the bounty to the pastor as his salary. The irrigation reservoir for the prastgard was listed on state records as Lagerman Reservoir.
