Clear Creek between Clear Lake and the City of Friendswood is in a natural state. Its bottom elevations are below sea level and subject to tidal influences. A number of natural and recreational parks have been developed along the creek, which are commonly referred to as the "Chain-of-Parks." The combination of Clear Lake, the "Chain-of-Parks", and channel reaches lined with dense woodlands provide a naturalized habitat along Clear Creek up to the Galveston/Brazoria County line. Much of the channel upstream of this line also supports heavy vegetative growth that returned following channel projects in the 1950-1960's. Some clearing has occurred to de-snag the channel or provide access to the channel from adjacent developments.
