Tri-City Regional Park is a 40-acre protected area located in the City of Placentia, on the border of the City of Fullerton. Within the park is a lake and three picnic shelters that you may reserve for special events. Activities include bicycling and walking the paved trails, model sail boating, fishing, and play areas.
Tri-City Regional Park also serves as a wildlife sanctuary for migratory waterfowl and it’s a popular location for bird watching.
The lakes and surrounding land at Tri-City Regional Park were once part of the Tuffree Reservoir. To meet the needs of the agricultural community, the reservoir was built in 1870 and provided irrigation to local farms.
In the 1950s and 1960s, urban development increased, reducing the city’s agricultural area. The area no longer relied on the reservoir for irrigation and the cities of Brea, Fullerton, and Placentia teamed up to develop Tuffree Reservoir and surrounding land into a public park.
Tri-City Park has been operating as a regional park as part of the Orange County Parks Department since 2013. The main park entrance is on Kraemer Blvd. at Golden Ave. A secondary entrance is on the opposite side of the park at Rolling Hills Drive.
