Humbug Creek Watershed Assessment and Management Recommendations Report (2015)

This 216-page report and 8-page executive summary are the result of the first phase of The Sierra Fund’s Malakoff Diggins Project, more than five years of collaborative science-based data collection, research, and analysis at Malakoff Diggins State Historic Park (MDSHP), part of the California State Parks system.

Gold Country Recreational Trails and Abandoned Mines Assessment (2011)

The physical dangers to recreationists at abandoned mine sites are well known, but the hazards associated with exposure to heavy metals in dust at abandoned mine sites are not well understood. This pilot study identified contaminants of concern (COC) at popular recreation areas around Downieville, Nevada City, and Foresthill, CA.

Gold Country Angler Survey (2011)

The Sierra Fund’s Gold Country Angler Survey was a study that interviewed anglers at local fishing locations, to learn whether they were being exposed to mercury by eating the fish they catch.

Results of the Gold Country Angler Survey indicated that approximately half of anglers at Sierra water bodies plan to eat what they catch that day, and nearly all report eating locally caught fish sometime in the last year.
