Aerial Flights over the SJRRP Area A Reclamation contractor will perform five aerial flights over the SJRRP Area in Spring and Summer 2010 to help monitor vegetation and extent of aquatic habitat during different Spring 2010 Interim Flow amounts. Aerial imagery will be collected by plane from an altitude of at least 9,000 feet. Spring/Summer 2010
U.S. Geological Survey Sediment Sampling USGS Staff will collect suspended sediment and bedload samples from five locations along the San Joaquin River to help track the movement of sand and gravel during Water Year 2010 Spring Interim Flows. Slated to occur eight times at each site from March to late May, the data will be collected at Highway 41, Highway 145, Gravelly Ford, Chowchilla Bifurcation and a site approximately three river miles downstream of Mendota Dam. Dependent upon flow conditions, samples will be acquired by wading across the river or from bridges, boats and/or a cable-way crossing. Sampling will be conducted from the public right-of-way or through advance coordination with landowners. The sampling will measure the amount of sediments moving through the water column and along the streambed. March – May, 2010
Bathymetric Surveys Initiated in Reach 1B California Dept. of Water Resources crews will conduct bathymetric surveys of the San Joaquin River from Highway 99 to Gravelly Ford. Conducted by boat, the surveys utilize sophisticated sonar to map the contours of a river channel.  Surveyor monuments stationed at concrete canal abutments operated by Fresno Irrigation District will serve as control points. Up to two aluminum skiffs and two kayaks will be deployed for the surveys. Boats will be launched and retrieved from Camp Pashayan, Donnie Bridge, Skaggs Bridge and Gravelly Ford. No land access is planned for the boat crews unless necessary for staff safety. Use of launch facilities, control points, and ponds connected to the river channel have been coordinated with landowners Beginning March 8, 2010, for up to four weeks
