Of the total area, 1.49% is water, consisting of percolation ponds in Los Gatos Creek Park and in other locations; San Tomas Aquino Creek, which flows north on the west side of the city, is completely enclosed with fences and runs through concrete culverts; and Los Gatos Creek, which flows north-north-east on the east side of the city and has paths along both banks for hikers and joggers (locally called the "Perc Ponds"). Residents are able to reach Los Gatos by continuing on the creek trail. Downtown Campbell contains many local stores and shops, and every Sunday the downtown street close from 8am-1pm for a local farmers market.
