The WY2021 OMR management season concluded on 8 June 2021 as specified in 2019 BiOp Chapter 4 Proposed Action (PA) and Incidental Take Permit (ITP).

2019 BiOp Chapter 4 Proposed Action (PA) https://www.usbr.gov/mp/bdo/docs/ba-chapter-4-proposed-action.pdf

	4.10.5.10.4 End of OMR Management:
	OMR criteria may control operations until June 30 (for Delta Smelt and Chinook salmon), until June
	15 (for steelhead/rainbow trout), or when the following species-specific off ramps have occurred,
	whichever is earlier:
	o Delta Smelt: when the daily mean water temperature at CCF reaches 77°F for 3 consecutive days;
	o Salmonids:
		o when more than 95 percent of salmonids have migrated past Chipps Island, as determined by
			their monitoring working group, or
		o after daily average water temperatures at Mossdale exceed 71.6°F for 7 days during June (the
			7 days do not have to be consecutive).

Incidental Take Permit (ITP), LONG-TERM OPERATION OF THE STATE WATER PROJECT IN THE SACRAMENTO SAN JOAQUIN DELTA https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/State-Water-Project/Files/ITP-for-Long-Term-SWP-Operations.pdf

	8.8 End of OMR Management. 
	Permittee shall operate the Project to meet the requirements included in Conditions of Approval
	8.3.1, 8.3.3, 8.4.1, 8.4.2, 8.5.1, 8.5.2, 8.6.1, 8.6.2, 8.6.3, and 8.6.4 to ensure that entrainment 
	and take of Covered Species is minimized during the OMR Management season through June 30, or until 
	the following species-specific off-ramps occur:
	o LFS and OS: 
		o Daily mean water temperature at CCF is greater than 25°C for three consecutive days.
	o CHNWR and CHNSR:
		o More than 95% of CHNWR and CHNSR have migrated past Chipps Island as determined by the Salmon Monitoring Team, AND
		o Daily average water temperature at Mossdale exceeds 22.2°C for 7 nonconsecutive days in June, AND
		o Daily average water temperature at Prisoner's Point exceeds 22.2°C for 7 nonconsecutive days in June. 

Monitoring will resume in October 2021 for WY2022.

Single-Year Loss Thresholds

Single-Year Loss Thresholds (PA 4-69)

In each year, typically January/February, Reclamation and DWR propose to avoid exceeding an annual loss threshold equal to 90% of the greatest annual loss that occurred in the historical record from 2010 through 2018 for each of:
