Don't Let a Little Rain Deceive You

It was an intense storm over the first weekend of March, but it didn't last long. And it certainly didn't make up for the dry conditions that have plagued our region for the last three years. Downtown LA precipitation for the season reached 5.6 inches, but we're near the end of the season, which usually averages 15.6 inches. Pasadena is at about the same level but has a higher seasonal average at 21 inches. The allocation on the State Water Project for this year is 0. That's right. None. So redouble your conservation efforts please, and let your friends and neighbors know the drought isn't over.

ASF Hosts German Sediment Expert

Dietrich Bartelt of the German hydrology firm, DB Sediments visited Pasadena last week to look into the sediment issue in Hahamongna. Dr. Bartelt has been tracking the Devil's Gate sediment program from Europe. He submitted comments to the County's DEIR. He came specifically to research Devil's Gate and sediment issues in Southern California.

Dr. Bartelt has extensive experience in sediment management and transport and emphasizes a more environmental friendly approach to the topic, which views sediment as a key part of river dynamics and health. You can get a better idea of his approach from this slide presentation that he gave in Chicago last Fall: Sustainable Sediment Management

Dr. Bartelt has an important message about the value of sediment that he delivered to County and Pasadena officals and a group of local activists. It may be that some of the techniques he proposes could help shape a more sustainable and environmentally responsible sediment program for Devil's Gate and Hahamongna Watershed Park.
