Heal The Bay Stream Walkers are the investigative sleuths of the Malibu Creek Watershed. Their responsibility is to get acquainted with the watershed in order to locate degraded habitats and pollution sources. Possible barriers to fish passage Illegal dump sites Illustrations by Chris Padick Discharge points and outfalls Discharge points and outfalls are pipes and culverts that carry storm water runoff into a stream at a single point. As a result, water quality and stream morphology may be impacted, especially at the point of discharge into the creek. Not all discharges are legal.
Current information regarding the location of all outfalls to the creeks is limited.
This information will help Heal the Bay update available mapped information. Unstable streambanks Unstable streambanks are a common problem along local streams, particularly ones that are subject to upstream development. Banks that are eroding or collapsing into the stream do not have stable soils for vegetation to establish. Eroding banks contribute sediments that can impact the habitat of steelhead trout and macroinvertebrates, and collapsing banks can block stream flows, causing flooding and damage to nearby property. Artificial streambank modifications often are used in urbanized or developing watersheds to prevent flooding.
