 Fontenelle Dam Fishing Report

The Fontenelle Dam Fishing Report is spring flows are about to cease and here comes the summer runoff adjustments. It’s hard to say exactly where the flows will top out given the uncertain amount of snowpack left up in the mountains. Our outfitter partners have said there is still a lot of snow left to come down. For the latest in conditions please feel free to give us a call @ 307-413-0669 or email: [email protected]

Greetings,

Runoff above Fontenelle Reservoir has increased significantly in the last few days.  Consequently, we anticipate increasing releases from Fontenelle Reservoir from 1,780 cfs (or full power plant capacity) to approximately 3,180cfs though use of bypass. Below is the planned schedule.

Fontenelle Flow Update

Greetings,

In an effort to minimize bypass releases, another step increase from 1,600 cfs to 1,700 cfs is schedule to occur on Thursday May 14^th.  Bypass releases are planned for late May or early June.  Based on the latest forecast, the May inflow is predicted to be 92% of average.  

After the final change at 9:00 a.m. on Thursday May 14, 2020, releases will remain 1,700 cfs until further notice.   

Thanks,

Dale

Wyoming Water Supply Outlook

HIGHLIGHTS:

…Wyoming February 2019 precipitation was 115 to 125 percent of average…

…Current water year precipitation is averaging 100 to 110 percent of normal across Wyoming…

…Mountain snowpack across Wyoming is 105 to 115 percent of median…

…Near normal to slightly above normal snowmelt streamflow volumes are expected across several major basins in Wyoming…

…Total reservoir capacity across Wyoming continues to be 70 to 75 percent by early March…

SYNOPSIS:

February 2019 precipitation totals across Wyoming were 115 to 125 percent of average. Precipitation numbers varied between 250 percent of normal over the Snake and Upper Yellowstone River Drainages (west to northwest Wyoming) to near 50 percent of average over the Tongue River Basin (north central Wyoming).  Current water year (October 2018 – February 2019) precipitation across Wyoming was 100 to 110 percent of average.

Mountain snowpack across Wyoming was 105 to 115 percent of median by early March.  Snowpack “water” numbers and/or SWEs were the highest across basins in southeast and western Wyoming—varying between 110 to 130 percent of median.  SWEs across basins in north central Wyoming were 80 to 100 percent of median.

Near normal to slightly above normal (95 to 105 percent) snowmelt streamflow volumes are expected across several major basins across Wyoming.  Above average snowmelt streamflow volumes are expected across the Snake, Shoshone, Upper North Platte and Laramie Watersheds.  Several rivers along the Tongue, Powder, and Upper Green Basins are forecasted to have below normal streamflow volumes during the upcoming snowmelt season.

Total reservoir capacity across Wyoming continues to be 70 to 75 percent by early March.  Reservoir storages across Wyoming remain above average at 105 to 115 percent for March.

The Upper Green River Basin Water Storage is sitting at 51% currently in the Fontenelle Reservoir. For those of you who don’t know, Fontenelle is the first dam on the Green River. The Green River above Fontenelle is a freestone for approximately 175 river miles. The New Fork River has a small dam that regulates the flow out of the New Fork Lakes as does the Boulder Lake dam which regulates Boulder Creek and the Fremont Lake regulates Pine Creek, which are all tributaries of the Green River. We’re currently booking for the 2019 season so please give us a shout to get your trip booked or just to catch up on the latest and greatest. 307-413-0669 or [email protected].

The Fontenelle Dam Fishing Report on the Green River has been good lately with most of the action mid day with straight up nymphing. The days we’ve been down there it’s been a bit breezy. Therefore 0 surface activity. The typical fare of sow bugs, midges and p tails has been the ticket with not a lot on the yield but those that have been caught are all solid specimens. Below is what we received today and as the spring melt kicks in expect to see more increases to the releases as time rolls on.

We’re currently booking for the 2018 season so please give us a call @ 307-413-0669 or email [email protected]. Thank you.

Hello:

Fontenelle Dam Release Schedule

Current forecasts are for increased temperatures over the next ten days with the potential for additional precipitation to manifest in the spring forecast. Spring forecasts become increasingly uncertain beyond 3-5 days and the flow increases are unknown at this time. Additional increases may be forthcoming next week. 

The increased inflows require increases in the releases according to the following schedule:

Fontenelle update:

The following data is why we’ve chosen not to guide on Fontenelle until after the runoff. This is now the 3rd amendment in a little more than a week AND there’s a Flood Warning on the Upper Green to boot. We are planning to guide on Fontenelle just as soon as the waters calm down from runoff, which we’re thinking should be around the beginning of July. The really good news is that we’re planning to guide well into October this season!

Greetings,

Increasing forecasts of runoff for the remainder of March and possibly April will require further increases in releases from Fontenelle Dam. Releases will be increased according to the following schedule:

* The mild valley temperatures will cause significant low 
elevation snowmelt runoff. 
 
* Flooding of smaller streams, culverts, and other low lying areas 
will remain a distinct possibility through this afternoon.

3.16.2017

Due to an increased forecast of runoff into Fontenelle Reservoir for the remainder of March outflows need to be adjusted.

Therefore, dam releases will be steadily increased beginning Thursday, March 16 and ending Wednesday, March 29, 2017 according to the following table:

                          Dam Release Schedule

Please note:

The current release schedule is subject to observed hydrology and is subject to change.

3.15.2017

From:     Jed Parker, Bureau of Reclamation                    

Subject:  Fontenelle Operations

The forecasted inflow for Fontenelle Reservoir between the months of April and July is anticipated to be 1,738,000 acre-feet which is nearly 240 percent of normal. In addition, low-level elevation snow melt is flowing into the reservoir causing the pool elevation to increase nearly two feet over the last week. As the downstream threat from ice jams has passed, the dam releases are planned to increase from the dam in anticipation of large inflows this spring.

Therefore, dam releases will be steadily increased beginning Wednesday, March 15, 2017 and ending Thursday, March 30, 2017 according to the following table:

Greetings Fontenelle Stakeholders,

The following is an update on hydrology affecting the basin above Fontenelle Reservoir as well as anticipated operations at the dam.

As of February 22, 2017, the to-date snow pack in the basin above Fontenelle was at 192% of median for a total of 145% of the seasonal median, historically wedged between two other high snow pack years of 2011 and 1986. The following graph demonstrates the snow water equivalent (inches of water present in snowpack) as those years progressed through the season along with the median (average between the years 1981-2010) and the current year’s snowpack. 

The following graph is a recounting of releases from Fontenelle in the years 2011 and 2016 (last year’s runoff) between the months of February and September. This graph is provided to demonstrate a high snowpack year (2011) compared to a roughly average snowpack year (2016). 

Fontenelle is currently releasing 1,025 cfs (cubic feet per second) which is expected to continue until the threat from downstream icing has passed. At which time releases will be increased to near power plant capacity (around 1,300 cfs). Going forward and depending upon further accumulation of snowpack, releases as early as mid-April may reach 4,000 cfs with early June releases reaching between 8,000 and 11,000 cfs.

While a variety of snowpack situations may play out over the coming months it is important for Reclamation to convey to stakeholders that the Colorado Basin River Forecast Center is now predicting a near 50% probability that the snow pack this year may be greater than the highest year on record for the basin above Fontenelle (1986). The facilities and procedures in place at Fontenelle Dam are sufficient to handle even the highest flows currently forecasted.

We look forward to working with stakeholders as we continue to analyze snowpack and reservoir operations and encourage anyone with concerns to contact us directly. A Fontenelle working group meeting will be held at Seedskadee National Wildlife Refuge in Green River, Wyoming on April 19, 2017, at 10:00 a.m.

Regards,

Jed Park

Fontenelle Dam Operation Plan Update

2.14.2017

Yesterday, I spoke with the person in charge of the Fontenelle Dam operation with the Bureau of Reclamation. He reported that there is a ton of snow above the reservoir and it will be quite difficult to project the exact operational plan until the ice begins to thaw. See the map below.

Wyoming Snowpack 2.14.2017

Once this happens, they will release plans as they become known and most certainly the plan will change multiple times. The MOST IMPORTANT aspect to keep in mind is, the operation is a reaction of what the weather is and subsequently how/when the snow melts. And that changes daily and sometimes hourly.

Currently here’s the latest from the BOR “Fontenelle Reservoir – Fontenelle Reservoir is currently at elevation 6,483 feet above sea level (feet), which amounts to 53 percent of live storage capacity. Inflows for the month of January totaled 44,600 acre-feet (af), or 148 percent of average. Average to above average inflows are forecasted over the next few months and releases have been increased in order to meet the spring elevation target. Releases have been set to base flow levels of 1,025 cubic feet per second (cfs) and are forecasted to remain at this level through the winter. Flows are anticipated to increase to 1,750 cfs on March 1, 2017 or whenever downstream icing threats have passed.”

Based on this information, Reel Deal is planning to operate and offer guided fishing trips this spring and summer above and below the Fontenelle Reservoir. Please keep in mind we guide from the Green River lakes up to the boundary of and below the Seedskadee NWR. This spring we will operate on a game time decision basis so PLEASE keep in mind that we DO NOT charge deposits for our spring trips so there is virtually NO RISK to our clients. If we feel the conditions are favorable, then we’ll go and if not, then we’ll either figure out another location or try again the next day.

One really positive thing to remember during big water years, the river corridors get flushed out and this is very good from a longterm, ecology standpoint for the riparian area. In other words EVERYONE and EVERYTHING benefits long term.

Our mainstay of operation will be from late June through October and we would like to remind everyone of our new mobile riverside camping option. If you’re looking to get your fish on then this is the program for you! Regardless of your plans, please give us a call at 307-413-0669 or email [email protected]. We look forward to getting you out for a great experience on the the water!

1/25/2017

The snowpack in the Wind River and Wyoming Ranges so far, are substancial and way above a 30 year average. Let’s hope the trend continues!

Current Status

(Last Updated: January 12, 2017)

Hello:

Fontenelle Reservoir is at elevation 6490.9 ft (68% full).  While August observed August inflows were 37 percent of average, significant precipitation has occurred over the Upper Green River Basin and releases need to be increased over the winter to meet the spring drawdown target.  

Beginning Wednesday, November 9th, 2016, at 8:00 a.m., releases from Fontenelle will be increased to 1,025 cfs according to the following schedule:                                                                                   

After the final change at 4:00 p.m. on Wednesday, November 9th, 2016, releases will remain at 1,025 cfs until further notice.

              Remarkable Rainbow

The latest Fontenelle Fishing Report we have is if you’re looking for some AMAZING dry fly action, we have just the experience you’ve been waiting for. Imagine stalking huge trout sipping tiny dries pod after pod; this is what we’ve been experiencing with our clients for the past few weeks. There have been zillions, literally, of caddis along with sallies and pmds all day every day. Don’t get me wrong, these fish are super smart and spooky but the patient angler can typically connect with a trophy. These fish are hot and powerful, so playing them is tricky business. Take your time and be mindful that you’re fishing in the high desert so keep ’em wet and don’t drag them out of the water onto the hot rocks along the bank.

                                Browntown

We have a new overnight camp here and we’re offering 2 days of guided fishing along with a comfy night in our 5th wheel or pop up camper. Our introductory offer for this option is $1600 for 2 people. Enjoy a grilled cowboy dinner and breakfast tacos for 2 in our super deluxe pop up camper and/or our 5th wheel. The pop up is for our single folks and the 5th wheel is for couples. The 5th wheel is the “mothership” that has a nice shower as does the pop up. Each has air conditioning as well for those hot afternoons. We have a huge selection of recorded music from our friends in Austin Texas to enjoy whenever. Imagine your self sipping a tall boy after getting off the water, being fed a killer dinner and chillaxing by the campfire telling stories about your daily stalking! Spending the night on the water means you can get on the water as early as you want.

Fontenelle Reservoir is currently at elevation 6488.74 ft (63% full) and releases are approximately 2,000 cfs. The current rate of inflow is roughly 3,300 cubic feet per second (cfs) and will continue increasing with forecasted precipitation and increasing runoff.

Due to recent storm activity, the forecasted April-July inflow volume has increased substantially since early May, and the official forecast issued in mid-May increased from 530,000 acre-feet to 650,000 acre-feet (90 percent of average). Fontenelle will be operated to accommodate the increased forecast.

Therefore, beginning Monday, May 23, 2016, at 8:00 a.m., releases from Fontenelle will be increased to 2,600 cfs according to the following schedule:    

After the final change at 4:00 p.m. on Tuesday, 24, 2016, releases will remain 2,600 cfs until further notice.  All times identified in this directive are local time (Mountain Standard Time) and not hour ending.

Every picture tells a story

The net width is 20″!

Fishing has been great this spring below the Fontenelle Dam and with the current snowpack, rains etc., the water supply looks to be ample for another great season!

We now have a riverside camping option this season to enjoy! We have a new Pop Up camper that has 2 separate sleeping ares, a shower and grill so we can cook up a killer dinner! There is a chef available to make breakfast and dinners too!

Fontenelle Wyoming Fishing Report

1.22.2016

Please read below for the latest from the Bureau of Rec which controls the dam at Fontenelle. Let’s all pray for at least a few more good storms to pack the mountains with good snow so the rivers are full all season long! We will continue to update our fishing reports and water/runoff reports. We are booking our spring trips below Fontenelle now so please give us a call to reserve your guide @ 307-739-7020.

Hi Rhett,

Good to hear from you! Fontenelle is currently down to ~6482 ft, which is about 52% of capacity. Since it’s relatively small, we draw it down pretty far over the winter to make space for spring runoff–we aim to get it down around 6468 ft by April 1st. Right now it looks like we’ll come in a little high because inflows have, to date, been higher than anticipated. Releases will stay constant at 950 cfs until April, when we’ll (hopefully) start to ramp up with the snow melt inflows. The forecast center has projected April-July runoff inflows at about 71% of average, due to the below average snowpack in the Green River Basin. Of course, that could easily change if we get a few good storms. Let me know if you have any additional questions!

Have a great weekend,
