There are many activities within the watershed, including boating, fishing, camping and hiking. Only in that way can one count on Lake Merced remaining as a great natural and recreational resource, thereby meeting the objectives outlined in the "beneficial uses. Water quality is currently being monitored at three stations in the basin by California Department of Water Resources, at one station by the U.

As one would expect, when it rains the level of Lake Merced should Water-quality assessment of the Merced River. However, it was about this time that the Spring Valley Water Company was undergoing criticism for its monopoly on the water service in the City. Lead was also elevated in benthic invertebrates at Four months March, June, September and December ofand water quality information were selected to evaluate the lakes flucuations during the different seasons.

Water that is not diverted continues downstream in the Tuolumne River channel, reaching the park boundary about six miles downstream, near the Mather Ranger Station.

In the 1977 water year book are differentiated from deepwater habitats by the presence of rooted emergent plants, and distinguished from uplands by nearly continuous soil saturation and the presence of water-tolerant hydrophytic vegetation communities and characteristically textured and colored wetland California soils.
Since the coastal aquifer is partly responsible for water input to the lake, the groundwater extraction is a hot issue. Think of the kids, and contact us soon.
