SED MO 1: Maintain a long-term 

balance of river-stored sand to support 

maintenance flow (in years of low reservoir 

storage), beach/habitat-building flow (in 

years of high reservoir storage), and 

unscheduled flood flows. Maintain system 

dynamics and disturbance by annually (in 

years which Lake Powell water storage is 

low) redistributing sand stored in the river 

channel and eddies to areas inundated by 

river flows between 20,000 cfs and 

maximum power plant capacity.

SED MO 4: Maintain system dynamics 

and disturbance by redistributing sand 

stored in the river channel and eddies to 

areas inundated by river flows up to 

45,000 cfs in as many years as possible 

when BHBF hydrologic and resource 

criteria are met.

REC MO 2: Maintain flows (under 

approved operating criteria) and sediment 

processes that create an adequate quantity, 

distribution and variety of beaches for 

camping, as long as such flows are 

consistent with management of natural 

recreation and cultural resource values 

(other natural resource values).

SED IN 1.4 Measure and model 

sediment contributions from all 

contributing sources, including 

tributary and high terrace sources.

SED IN 1.5 Evaluate the 

geology/geomorphology within 

Glen Canyon to: (1) determine 

historical changes in size and extent 

of beaches, sandbars and 

backwaters, (2) quantify sediment 

(size class and quantity) input from 

side channels, (3) understand bed 

morphology dynamics, (4) evaluate 

high terrace erosion and 

contribution to river sediment.

SED IN 4.3 Develop an 

assessment of dam operations 

under approved operating criteria 

impacts on range of variation in 

sediment and other resources 

within Colorado River ecosystem 

and the associated processes that 

created these ranges

REC IN 2.1 Determine adequate 

beach quantity, quality, distribution, 

character and structure for camping 

throughout system.

REC IN 2.2 Evaluate impacts of 

operating criteria on establishing 

and maintaining adequate beaches 

and distribution of other resources, 

quality, character and structure.
