However about January of 2015 they have now a link on their website for River Levels/Lake Levels. This is updated periodically so may not be exact, having a lag time, but a great help non the less.

This lake was formed when Tacoma
City Light completed the Mossyrock Dam in 1968. By the way,
the name of Tacoma City Light has now been changed to Tacoma Power. This
lake is a large 23 mile long reservoir that stretches along US Highway 12 east of Mossyrock
which has a shoreline of 52 miles. It is located about 90 miles south of
Tacoma Washington. Riffe Lake can be
reached from I-5, turn east onto US Highway 12 and go about 20 miles to the
town of Mossyrock. At the stoplight on Highway 12 at Mossyrock, turn
right (South) on Williams St. and go into town. Go 4 or 5 blocks and past the school you
will come to a Tee intersection, take a left and go east through town. Keep
going on this (the old highway) which leads directly into the Mossyrock Park Campground.
When full at a pool height of 778' it has 11,830 surface acres of water.
NOTE -- as of 2017 Tacoma Power has lowered the
summer maximum pool height to 749'. They say for downstream SAFETY
sake that in case a A MAJOR
EARTHQUAKE HAPPENS there may be a possible breach in
the downstream dam pillars .
For a newspaper article explaining this,
CLICK HERE. So don't be lulled into thinking the lake will be at full pool height
when you read their web that it is at 745' of 749', where the old pool maximum
height was 778', as now they are maintaining summer height 30' lower than it was
originally. And during 2022 no plans seem to be in the works to rectify
the issue.
Mossyrock Park boat launch short lane will be unusable when the reservoir is at approximately 713 feet elevation, but the long lane is usable to approximately 708 feet. The Taidnapam North boat launch is usable to approximately 719 feet.
As of February of 2019, the water level was dropped dramatically low because of all the snowfall, but not a lot of rain, (679') in anticipation of a lot of snowmelt. An aerial view looked more like a river than a lake. And all boat launches are closed even into mid May.
If you don't mind hiking in mud, there is a good chance of refilling your tackle box with lost fishing lures.
Here these guys had to drag their boat a considerable distance at Mossyrock Park boat launch on 4-20-19 with a lake height of 698', but fishing was worth the effort for them |
At the original full pool height, the water depth in places can reach 360'. It initially was named Davisson Lake after an engineer overseeing the project, but local pressure prevailed and it was soon changed to the name of Riffe Lake in favor of the small town that the upper end of the lake that got flooded out.
|
This lake is an impoundment that of course is a power generation dam, but also is basically a catch basin used for flood control of the snow run off from the higher elevations around Packwood and Randle. With this in mind, the lake is lowered in the late fall in preparation to the estimated winter rains. Then in the early summer (anywhere from the 1st of April to about the middle of May) when the rainy season and any possible flooding appear to be over with, the lake is allowed to raise again for storage during the summer months.

Boat Launches :
The The
Mossyrock Park is located at the lower end of the lake is run by Tacoma
Power that has slightly over 200 family RV campsites, with many more
individual tent sites. Phone
number for Mossyrock Park, 202 Ajlune Road, Mossyrock WA 98564 is 360-983-3900,
which has two boat launches.
Old Highway
Launch ; (1)
From
Highway 12 at Mossyrock, turn south, at the Shell service station, (Williams St.)
and go into the town of Mossyrock. About four blocks (and past the school) you will come to a
Tee, (either right or left). Turn left onto State Street, and continue past the business
district and out of town
where State Street becomes Mossyrock Road East and then farther out yet it becomes Ajlune Road. At about 2 miles, go straight ahead at the
intersection of Swafford Road and another mile you will come to Riffe Lake
Campground, you need to turn right into the park, maybe talk to the ranger if on
week-ends and/or pay the fee, then
hang a immediate left behind the gate shack to the old road, then a right back onto
the old highway. The distance to the launch at full lake height, is only about 300'.
This launch is on the old blacktop highway 12 that is now covered by the lake. This highway gently slopes down into the lake behind the dam. There is small parking lot on the north side of the road /launch with a turn around into the lot above the wooden floating docks. At full lake height during the summer the dock provides access. Depending on how many others are using this launch and the lake's level, there may be some distance to back down. At a lower lake height when the lake is drawn down, you might want to walk this old road before launching to locate possible debris and or mud. This launch is usually used by smaller boats and not recommended for larger trailered boats because of the shallower sloping road/launch. There is a Sani-Can here at the edge of the parking lot along with a couple of garbage cans.
After a hang-glider from dog Mountain on the south end of the lake went down during the winter of 2019, along the steep west side of the lake, and the Mossyrock ramp was not accessible for a Search and Rescue boat, Tacoma Power removed the debris off this old road to facilitate that rescue by boat. Now they have agreed to keep this old road open, so even if the newer extended Mossyrock launch is unusable, maybe the recreational fishermen could have winter drawdown access (but kept there promise ???).
At the new lower pool height, this launch is questionable that it is usable when the Mossyrock park launch is usabl.

Mossyrock Park ; (2) This is the most used launch, go as described in the #1 above but when you come to the entrance to Mossyrock Park, go straight ahead. The office/gatekeeper is open during the camping season, if it is open, stop and tell them you are going to the boat launch if they are there and on week days. This road is on the right and slightly above the campgrounds with the launch located on the SE end of the campgrounds. The upper launch is blacktop with four lanes, with concrete slabs below, and has a nice slope which enables you to back in and launch with a car, pick-up or even a motor home. It had a floating dock of about 100 ft. long on the south side of the ramp, (as seen in the RH photo below, but was removed completley when the pool height was lowwered) and a longer one in the center for passenger loading into the boat when the pool is full height. This launch area has ample striped individual paved parking, restrooms, picnic tables, a fish cleaning station and very nice toilet facilities.
Mossyrock Park launch in the summer with a full pool height of 778' | Mossyrock Park launch in early March with the lake lowered to 736', before the lower dock was installed. |
This launch was upgraded in 2007 to make it usable most of the year, even when they draw the water down in the fall and winter in anticipation of the winter/spring rains. If the water was at the end of this dock (RH photo above) the pool height would be 751'. 'To use the dock, it will have to be about 760', anything lower than that, the NW dock will be high and dry. The ramp is however still usable until the water level reaches approaching 725 feet. Depending on your boat, even at a pool height of 735' you might want to walk the ramp before launching to locate possible debris and or mud as shown in the above RH photo if you are early in the season.
Tacoma Power had planned on finishing it to the lower level of about 705' but not sure that happened. In the photo below 04-25-2021, the water level was 705.2'. The south side ramp is mudded in and they were relocating spme of this mud to the upper south side of the ramp, but the ramp was closed during this operation/
The word is from those that use it regularly that at a pool height of 710' the ramp is usable for the north lane and on the concrete slab. By the time the height is up to 720' the dock should be usable.

Day-use parking and usage of the boat launch free except, weekends and holidays only, Memorial weekend through Labor Day weekend, which is then $5.00 per vehicle. This day use permit is hard to miss as it is printed on a bright colored 8 1/2" X 11" sheet of paper, which is color coded for the days. Other than the above time frame, no fee is charged.
The current water level height and reservations for the parks can be obtained by calling Tacoma City Lights fishing hotline at 1-888-502-8690. Or it is now (Feb 2015) available on the internet, CLICK HERE.
On April 18th 2015, with the pool water height at 769', the water as just at the lower end of the south end docks.
Riffe Lake Campground ; There is another park nearby, Riffe Lake Campground is close by which offers more private wooded sites near the lake (no beach or launching access however). It is a more private location than the Tacoma Power's Mossyrock Park, while still near Riffe Lake. This was privately built by lifetime resident John Hadaller and now owned/operated by his daughter. This campground was there even before the lake was created, it also offers an experience more akin to camping rather than a small city on a lawn. This campground is a clean and well kept campground, each spot with a picnic table and fire pit. Do not expect to be on the lake, you will however be overlooking it and close to Swofford Pond.
The directions are the same as to Mossyrock Park, except
before you get to the park, the road Y’s, stay Right onto Swofford Rd which turns
into Green Mountain Rd., Go 2 Miles. Turn Left onto Osborne Rd. The
destination is about 1/2 a mile at the end of the Osborne Rd. For a link
to it

Kosmos ; (3)
This launch is on the east side off Highway 12 past Morton on
the Kosmos road. This is located in Sand Creek bed, and again if the water
is too low in the fall it has it’s problems. There is ample blacktop
parking, however at times of heavy use in the summer I have seen it full.
This one is used mostly by fisherpersons who fish the upper end of the lake,
trying to avoid the water skiers who seem to concentrate nearer the Mossyrock
Park launch. The picture below it is looking across the lake toward
Taidnapam
Park on the left hand point.
When the pool height gets low in the winter, the steel gates are closed and locked on the road leading into this launch, as the small creek that is left in the channel is about non-existent below this ramp at this time.

Taidnapam North Launch ;
(4) This was proposed by Tacoma Power to be completed by the
spring of 2007. As of April, 06, some work had been started and it
was completed the summer of 2008. It is constructed just northeast and near Taidnapam Park,
and is to be more of a year around launch
for the upper lake with the ramp extending to about the 720' level. It will start at about
25' above maximum pool height. It is a LONG launch, with pull-outs
stationed at intervals to facilitate turn-arounds at different pool heights
instead of making boaters back a LONG distance at low water.
I was there 10-20-07 and took the photos below, but construction is not yet
complete. Apparently because of the flooding that took place the winter of
2006/07.
There is a large parking lot,
nice restrooms, a prep area on the right at the top of the ramp with a
blacktopped loop to the right for pulling in and then heading back south to line up the
trailer to the ramp backing north. The upper section is poured scored concrete, with a
lot of large pre-poured interlocking sections apparently to be used for the
lower section stored in the edge of the parking lot. The
smaller white hand written sign says "boat launch unusable" with a date of
10-15-07 as there is a lot of mud on the ramp at the water level.
Now they have added a movable dock, that is raised/lowered to the water level by a cable laying up the middle of the ramp. At a low pool height, there may be underwater obstacles, like stumps or gravel bars if you were accustomed to fishing this at a high pool height which you were never aware of.
They did extend the Taidnapam Park North ramp to 720' and do use a floating dock, but it is a lot longer drive to get there. And at the new low drawdown level, the low end of the ramp is not usable.
Sign at the entrance | This launch is loooong & has some turn-arounds part way down. Here the pool height is 726' of a total fill of 778' |
Taidnapam Park South Launch; (5) The other ramp is located in Taidnapam Park, which is another Tacoma Power facility. Phone number 360-497-7707. Go to the entry gate and pay the parking fee if applicable for that time of the year. This has a concrete ramp, fish cleaning stations and restrooms. The one thing on this ramp is that there is a major drop-off off the end. It has a concrete bumper at the lower end to stop a trailer from dropping over. There is about a 50' drop off beyond this bumper. THE BUMPER IS IT. If the lake level is being lowered, DO NOT ALLOW A TRAILER WHEEL TO DROP OVER THIS BUMPER. The end of the ramp and bumper is at about 6' beyond the end of the floating dock. Under these circumstances I would not recommend trying to launch a large boat here unless you check it out completely first as the drop-off beyond the bumper stops is considerable if you view it at a low pool height.
This ramp is generally usable late May to mid September, depending on lake
level. Parking for the boat launch free EXCEPT, it is $5 per vehicle, weekends and
holidays only from
Memorial weekend through Labor Day weekend. This ramp of course would also be not usable at a real low water
level in the late fall or winter. The park rangers post signs as to
the ramp being closed and they close and lock the steel gates
at the top of the ramp under these conditions.
Fishing
Regulations :
Your trout (or landlocked salmon)
combo limit here is 5 fish
total,
and this lake, like
all waters of the state have a restriction whereby if you use bait, any that you
catch will be counted toward your limit regardless if your keep or release them.
However if you are using lures, with no scent, you can cull or release them all
day. For this lake, WDFW has designated it as a 2 pole lake if you purchase
that endorsement. And for some reason you do not need the Columbia River
endorsement ???
Here a fisherman using it's 2 rod endorsement |
Fish ; Many of the fish that are in the lake are named silver trout, (essentially a landlocked Coho), with a size from 12" to 16" and even an occasional one up to 20”+. With the best fishing for them starting in the early spring. This fishery is because of the inability for downstream migrating smolt to be effectively trapped at the Cowlitz Falls dam above this impoundment. You may even catch a landlocked Chinook (that have went through the turbines of the upper "Cowlitz Falls dam") in the mixed bag. Also some rainbow that were planted in lake Scanewa "the Cowlitz Falls dam impoundment" for the yearly juvenile fishing day.
There also seems to have been an increase in what some people consider Kokanee here. However if you ask Tacoma Power biologists, they say there are no Kokanee there, however this is a little beyond their interests as Riffe Lake seems to be "No Mans Land", kind of between two other dams and the fish population not on their radar at any time other than the first years plant. He did say that there may be a possibility however of a few surviving and thriving from the first year's plants. However many may confuse Kokanee with the landlocked Coho, but look for SMALL scales and large eyes and a forked tail for the Kokanee. About the only true way of telling the difference is to look at the gill rakers. Salmonid type fish eat other fish and have shorter rakers spread out about the length of them, while Kokanee have longer and closer together rakers designed to filter in the plankton and water out. But the limit is the same for either or a mixed bag under the landlocked salmon designation so no one really cares.
