The Alamo River appeared to have poor water<br />
quality; it is reportedly largely comprised of irrigation<br />
return flows. However, it likely harbors fish and it<br />
is worth noting that there is no specific state fish<br />
consumption advisory against fish caught from this<br />
waterway.<br />
Resource staff surveyed California Department of<br />
Transportation (Cal-Trans) undeveloped lands to the<br />
east of the park for potential acquisition as identified<br />
in the General Plan.<br />
South Alamo Canal<br />
The recreational fishing resources of the South Alamo Canal and the Alamo River are<br />
limited, both by access issues and probably by low numbers of desirable fish. While public<br />
access to the South Alamo Canal is apparently not prohibited, neither can it be encouraged<br />
except by Imperial Irrigation District. While irrigation canals are known to pose a potential<br />
public hazard and state public safety campaigns exist to warn against canal entry, it is<br />
worth noting that similar public fishing access is explicitly allowed and even encouraged in<br />
other regions of the state.<br />

Rancho Road and Lodge Lake Project and Sediment Basin Maintenance<br />
Sediment basins are among the park’s top sedimentation control BMPs. Basins were<br />
built throughout the park in various drainages and at the bottoms of hill climbs to capture<br />
sediment that has been mobilized by rain<br />
runoff and OHV use. During the rainy<br />
season, sediment basins fill up with water<br />
and deposit sediment at the bottom of the<br />
basin. Throughout the summer months, the<br />
water level in the basins drop and eventually<br />
completely dry up. Following a schedule<br />
determined by the park’s environmental<br />
scientists, the equipment operator uses<br />
an excavator to clean out the basin of<br />
accumulated sediment. Depending on the type<br />
Rancho Road before rehabilitation<br />
of sediment being removed, the moisture content, and the location of the basin within the<br />
park, the equipment operator will either stockpile the material or apply it directly to a road<br />
