2018 McPhee Release Update

Thursday March 15, 2018McPhee currently releasing 50 CFS for the downstream fishery. Releases will continue at this rate until ramping up to 66 CFS for tomorrow, which will continue to the end of the month. Releases in April are anticipated to be 50 CFS; however, due to the variability in the current runoff forecasts, planned downstream releases in April and beyond are subject to change. The runoff forecast has dropped since January: as of March 1st, the CBRFC 50% exceedance forecast for McPhee April through July inflows was only 113,000 AF. The SNOTEL sites are averaging only 46% of the median snow pack as of today, March 15th — down from the beginning of the month.

Based on these forecasts, it is highly unlikely that a controlled release from McPhee will occur this year.

We will update this page again in April with any new developments.

DWCD 2018 Outlook for McPhee and Dolores Project Irrigators

Current forecast odds are barely enough for a full irrigation supply in 2018, with the CBRFC 50% forecast having dropped 20 KAF in the last month.  Carry over storage is likely to be low and threatens the 2019 supply.  More updates in early March.

CBRFC Exceedance Worst Case 90% 70% 50% – MP 30% 10%
Forecast Inflow  KAF

(April – July)

46 61 86 110 155 200
% Supply 77% 82% 95% 100% 100% 100%
FSA Contract Allocation Inches/Acre 17” 18” 21” 22” 22” 22”

 

MP – Most Probable, 50/50 chance, coin toss, median forecast based on historical weather & resulting hydrology.

FSA – Full Service Area, Yellow Jacket to Dove Creek (No adjustments are made to irrigation pools that could increase based on M&I lease, Class B & Water Bank)

The 30 year average April through July runoff for McPhee is 295,000 acre feet.  We have the potential to collect precipitation towards the spring runoff through May.

The grim February forecast followed January’s continuing lack of snow.  At the beginning of this month, there was only about 40% of the normal snow pack with a high pressure ridge is persisting over the western US, diverting the majority of precipitation to the north. Based on the current conditions the forecast only gives a 3% chance of the Dolores basin reaching average runoff this year. If the high pressure ridge breaks down in March we should see the storm track return to our area.  If high pressure remains we’ll continue missing more normal precipitation.

McPhee currently has 132,000 Acre Feet of active storage that can provide nearly half of the 2018 water diversion needs for our community.  This higher than normal carry over provides some insurance given the current conditions.  With inflows remaining on the low end, carryover into 2019 will be low and increase the potential for future shortages.

Dolores Project Municipal supplies are not subject to shortage based on contract and/or senior water rights in some cases.  This applies to MWC, Cortez, Towaoc and Dove Creek.

2018 McPhee Release Update

Wednesday January 10, 2018McPhee currently releasing 40 CFS for the downstream fishery. Releases will continue at this rate until March 1st, when they will increase to 50 CFS, then to 64 CFS on March 16th. Current runoff forecasts for the Dolores are not optimistic, with a 50% probability that McPhee could receive only 130,000 AF this season, according to the Colorado Basin River Forecast Center. The SNOTEL sites are averaging only 31% of the median snow pack as of January 10th.

Based on current runoff forecasts, it does not look like a controlled release from McPhee is likely to occur this year.

We will update this page again in mid-February with any new developments.
