Going fishing soon? Is it a good idea to eat what you catch from your local river, stream, reservoir or lake? Check it out at...
Now that winter rains have arrived, check out your local stream or river to see the changes! It's still possible your nearest stream may not have water in this 4th year of drought. However, if your stream now has water flowing again, you can use our Rivers & Streams Portal to see what to look for. As winter weather & this year's El Nino effects come on & for your own safety, please stay away from any landslide or flash flood hazard areas during and following major storms.
How does recreation at your local beach look? Is the water quality OK for wading, surfing, or swimming? Check out your nearest ocean beaches, Lake Tahoe, Eldorado County and San Francisco Bay area spots at: http://www.mywaterquality.ca.gov/safe_to_swim/. Remember the water is not healthy & safe for 3 days following a major storm, due to polluted runoff.
2014 SWAMP Review: In 2014 SWAMP conducted an internal programmatic review to evaluate program functions and effectiveness, and to recommend actions to ensure the program's continued success.
The Stream Pollution Trends Program (SPoT) has a new web page on the SWAMP website and the 2014 SPoT report has recently been released. Please review the new web page and see five years of data trends in the 2014 report, Trends in Chemical Contamination, Toxicity and Land Use in California Watersheds.
