Back in 2013, we constructed a new rock-and-pool fishway at the outlet of Coleman Pond in Lincolnville, Maine. Coleman Pond is in the Ducktrap River watershed, which is home to a very small and genetically distinct run of endangered Atlantic salmon.
The old outlet dam was deteriorating and did not have any form of fish passage. Working with professional engineers from Kleinschmidt Associates and the NOAA Restoration Center, we developed a plan to build a natural looking fishway that would allow alewives, Atlantic salmon, American eel, and brook trout into and out of Coleman Pond. The design would also provide for greater control and management of water levels in Coleman Pond, a great benefit for camp and home owners. Following construction, the State of Maine began stocking Coleman with alewives and 2017 would be the first year that we would expect to see any adults returning from that seeding.
In late June I visited the fishway with the hopes of seeing some alewives even though we are near the end of the run and we likely would not have many 3-year old fish returning to the system. But, lo and behold, there were 10 alewives milling about in the top pool of the fishway when I got there. A small amount of debris was blocking the notch in the top weir that they needed to swim through to get into Coleman, so I spent about 15 minutes clearing the sticks and muck from the area. Within a few minutes the alewives started popping up into the pond, hopefully to join many others that had previously made that last jump.
Today was the first time that I had been back to the fishway since the autumn of 2013 and I was curious to see what condition it was in after 4 winters. The fishway looked fantastic and had held up perfectly. I look forward to returning to Coleman Pond in 2018, hopefully a few weeks earlier, to see what should be a run of several thousand alewives.

This past week I spent time in Cheticamp working with the local group the Cheticamp River Salmon Association and NSSA Past President Rene Aucoin, of that group.
We held our annual fly casting/fishing session with students from the local school. This is a great event and lots of fun for the kids and the association volunteers. Joel Camus, a CRSA member owns a lovely property with a large lawn where we can teach the kids the basics of fly casting and he has a spring fed pond stocked with large trout.

The kids learn how to do a simple pick up and laydown cast, some key knots for fishing and then we let them cast to the fish. They learn how to work the fly, set a hook when the fish takes and how to play a fish. Many of these fish are in the 4-5lb range so the kids have quite a thrill when the catch one. This program has introduced many youth in the area to the life long sport of fly fishing and some become instantly addicted to the sport.
After this session, Rene and I explored a large section of the Cheticamp River, observing changes that with restoration work has done and also seeing the changes up river from the big flood of 2015. It was amazing to see the changes to the river. Some older established pools had changed, some for the better some not so much. But what was really impressive was the number and variety of new pools formed. We saw what looks like more and improved spawning areas and much more overwintering areas for juveniles.

Rene and I chatted about the need now to begin naming the new pools. Not a bad task, having to re-explore and learn a river again, one that you have known your entire life.

There is a lot of cool work being done on the West River Sheet Harbour.
This week researchers from Dalhousie were on-site to aid in mapping and recording river habitat prior to some major work being conducted on the river. They used a drone to map the river channel and record habitat details. It was quite impressive to watch and to see some of the images that were being recorded. This will provide a valuable record of pre-treatment work and a good way to see the changes that will occur with the work.

Drones have been used in habitat mapping work in other areas, but this is my first real experience with them. It is incredible technology with many potential uses.

Twenty five years ago, in 1992, the Fish Friends program began in New Brunswick.
Twenty five years ago I was in grade one, and among the first cohort of students to receive Atlantic salmon eggs in an aquarium in my classroom.
Over the coming months, my fellow classmates and I learned about their complex life cycle and watched the eggs hatch, develop into alevin, and then fry. We would go on to release the fish into a nearby stream in June so they could continue their life cycle and we could move on in our lives as young environmental stewards. Fast forward to 2017 and this week elementary school students from the Oromocto area released their fry on Base Gagetown after the very same process of learning about the wild Atlantic salmon.
Not only were the kids excited for the culmination of their project, but on hand were an enthusiastic group of adults representing a diverse range of organizations, including the NB Salmon Council, Oromocto Watershed Association, NB Natural Resources, Fisheries and Oceans Canada, the Base Commander and personnel, Canadian Rivers Institute biologists, myself from ASF, and last but not least, the Lieutenant Governor of New Brunswick, Her Honour, Jocelyne Roy Vienneau. The adults were nearly as excited as the kids on the cool but optimistic-feeling early June morning.
Now run by the New Brunswick Salmon Council, the program has stood the test of time as an environmental awareness staple in over 100 NB classrooms. Other classes will be releasing their fry over the next two weeks throughout New Brunswick, and in fact, all over Atlantic Canada, Quebec and Maine. Good luck young fry—please return, and thank you to the young students who raised them.

This past week, the crew from the West River project along with NSSA staff and a number of volunteers, installed the Resistance Board Weir counting fence on the West River, as part of the overall monitoring.
The West River Sheet Harbour for a decade has had a lime doser increasing the pH and mitigating the impact of acid rain. This impact was largely due to the coal-fired power plants of the Ohio River valley.
Installing the counting fence weir is a pretty efficient operation, but does require a number of people to help carry the heavy trap sections. The longer fence sections can be floated into place, connected to the bottom rail and joined together pretty smoothly. It was a well choreographed process.
Staff from Parks Canada were also on hand to assist and learn about this fence for potential use in other systems.
As you can see from the photos, a classic case of many hands make light work.
Wildly fluctuating water levels in 2016 (from record drought to flood conditions) resulted in less than ideal operating conditions for the fence, but even the modest returns seen last year are going against the downward trend in the other acid stressed rivers on the Eastern Coast of Nova Scotia, show us that the liming project is working.
With the smolt wheel still running and the fence installed, the West River crew are a busy lot these days.
