The golf course was designed by Ted Robinson Sr.[5] The dam and half the lake is owned by the city of Santa Rosa as the Nagasawa Community Park.

Fountaingrove has significant aquatic as well as upland biota, and is noted for being a habitat of the Western pond turtle, Actinemys marmorata, a "Species of Special Concern".

[8] The microclimate at Fountaingrove Lake is a mild Mediterranean climate typical of southern and central Sonoma County.

[10] A 500,000 US gal (1,900 kl) water storage tank was proposed near the southern end of Fountaingrove Lake; the city of Santa Rosa has approved this project to add to the municipal drinking water supply, subject to erosion control measures to protect Fountaingrove Lake from excessive siltation.

On site mitigation measures include extensive erosion protection for cut slopes and installation of bioswales.
