Background and Follow-up Information
for classes in Water Ecology
Course Descriptions
- Water Ecology 4th through 8th graders help us investigate the health of a mountain stream from a rainbow trout's point of view. This includes testing for four water-quality parameters, and sampling aquatic indicator (insect) species. A great way to introduce or reinforce the scientific method and experience hands-on science at its best.
- A River Runs through It 4th through 12th graders experience actual hands-on science at its best. Students will investigate the water quality of the San Gabriel River. Elementary and Junior High classes will utilize test tablets and color charts to test for four different water quality parameters. High School classes will utilize Calculator Based Laboratory (CBL) technology. We will measure stream flow, pH, dissolved oxygen, ammonia and nitrates. All grade levels will have access to microscopes and a flex-cam to observe micro- and macro-aquatic life.
Overview of the Watershed
The San Gabriel River is the largest water feature in the San Gabriel River Ranger District of the Angeles National Forest. The East and West Forks separate the mountains into two roughly parallel ranges ... the lower Front Country on the south and the High Country to the north. The North Fork drains the High Country around Crystal Lake and Mt. Hawkins. The West Fork and its tributary, Bear Creek, drain the area from Mt. Wilson to Islip Saddle and the East Fork drains a vast area from Mt. Baldy and Mt. Baden-Powell westward. Where all three forks connect in almost the same place, the river changes direction and flows directly south ultimately to the Pacific Ocean.
San Antonio Creek in the next major canyon to the east collects water from the southern slopes of Mt. Baldy. The larger tributaries are Icehouse Creek to the east and a different Bear Creek to the west. San Antonio Creek is channeled through the Chino Basin to the Santa Ana River.
There are many ephemeral streams flowing most fully after snow melts and heavy rainfall.
Most of the time this is a land of upside-down rivers, with stream beds on top and water flowing beneath the sand and gravel.
Crystal Lake is the only natural lake. Continually spring-fed, it was formed after a rock avalanche deposit.
Reservoirs built on the San Gabriel for flood control purposes are Cogswell on the West Fork, the San Gabriel and Morris on the main river itself. All three are now owned by the LA County Flood Control District and operated by Public Works.
