On Saturday, volunteers will walk lengths of the San Pedro River as part of an annual survey of the river, recording the distances on the streambed where water is present.

Researchers will use the data to analyze trends in surface water patterns, manage fish and wildlife populations, understand groundwater and surface water interactions, and design and implement ecological research and monitoring.

"It's important to see to see how the wetted lengths persist through the dry parts of the year," said Molly Hanson, Lower San Pedro River program manager at the Nature Conservancy.

The survey has been orchestrated by environmental group on the third Saturday of June since 1999. Hanson said that it will be interesting for researchers to see how the wet areas this year, which has been particularly dry, compare to past years. 

Hanson is leading a training session on Friday at 5:30 p.m. at the Lower San Pedro River Preserve in Dudleyville to teach volunteers how to record the wet and dry segments of the river with a GPS system. For more information, visit the Nature Conservancy's website
