City of Calgary River Flow Advisory – Keep Off the Bow River

Press Release

City of Calgary River Flow Advisory

Date, June 01 2017

The Calgary Fire Department, Calgary Police Service and Calgary Community Standards are advising Calgarians against boating and all other watercraft activities on the Bow River.

The current flow rate on the Bow River is 293 m3/s — which is higher than we’ve seen in the last two years,” says Carol Henke, Public Information Officer, Calgary Fire Department. “Runoff from melting snow in the mountains is causing very cold water temperatures, increased floating debris and high turbidity in the Bow River, which makes for very poor visibility and dangerous conditions.”

Members of Calgary Fire and Calgary Police marine units will be monitoring the river while the advisory is in place. However, The City advises everyone to stay off the Bow River until conditions improve.

For the safety of river users and emergency responders, we are asking everyone to wait until flows return to normal, Henke says.

It is also important for people near the river to be aware of high flow levels. “Calgarians are urged to exercise caution around river banks as the fast-moving water can cause erosion and river banks can collapse,” Henke adds.

Harvie Passage remains closed to recreational boat traffic until 2018. The province of Alberta continues to restore the passage and during this time this section of the river poses extreme risk.

As always, Calgarians are reminded to use caution and be prepared for anything on the water. All watercraft users should wear life-jackets to avoid a mandatory court appearance and fines. In addition to wearing life jackets, river users should avoid consuming alcohol and other intoxicants on Calgary’s waterways.

The City of Calgary encourages all water users to familiarize themselves with safety practice bylaws and safety alerts on   and monitor flow levels at   

Boat Ramp Etiquette

As the Bow River as a recreational venue becomes more popular, there is a need to be considerate of other river users. Boat ramps can become congested with not only drift boats, but canoes, kayaks and all the gear that goes with a day on the river.


Recently the Angling Outfitters & Guides Association of Alberta (AOGAA) prepared a brochure entitled Etiquette & Fish Handling Tips  that gives suggestion as to how to avoid problems and conflicts at boat launch sites.

This is an excellent review from river guides who use the river on a daily basis.

022As the Calgary River Access Strategy rolls out, each of the boat ramps and hand launch sites will have information boards, similar to what has been installed at the Glenmore Reservoir boat ramps detailing river use information and guidelines. Boat ramp etiquette and safety will be a part of the information.

Join Bow River Trout – Support the Bow River Fishery

The Future of the Bow River Fishery:

The Bow River fishery is recognized around the world for the quality of  Brown and Rainbow Trout.  The Bow River needs support from the angling community to assure a sustainable fishery not only for ourselves, but future generations.

We are excited to launch a new organization for the fishing community that is totally committed to the Bow River fishery. Bow River Trout Foundation wPCS10as formed by a group of like-minded local fishermen who volunteered to give back to the world renowned Bow River for years of angling pleasure.

Our founding directors have developed 8 objectives that will serve to protect the interests of Bow River anglers and to sustain a viable fishery. Our primary focus is to support responsible use and enhancement of the fishery while assuring public access and protection of riparian habitat that benefits the Bow River ecosystem.

There is also a need to engage the public and cooperate with all levels of government and organization or stakeholders with similar interests as our own. In other word;

Bow River Trout will advocate for the interest of  the fishing community.

Recent Developments:

 Bow River Trout (BRT) has been an active participant in the stakeholder consultation with the Calgary River Access Strategy. Two new boat ramps will be commissioned within Calgary over the next two years.Ogden Bridge, downstream of Harvie Passage will be developed in 2017 followed by Inglewood in 2018. The City of Calgary has committed $7.6 million to new and enhanced river access over the next 5 years. BRT as a member of the Calgary River Users Alliance has been asked by the City of Calgary to financially support river access developments. BRT will contribute through our fundraising activities. Alberta Environment & Parks has started stakeholder consultation to improve river access outside of the City of Calgary. The Bow River Access Plan will be made public later in the spring.

Bow River Instream Work -2017 Update

The following is an updated list of instream work that will take place in the Bow River during 2017. Instream work can only be conducted from April 06 to May 01 and July 15 to September each year to protect spawning fish. It is important to recognize that any instream work is covered by extensive Provincial and Federal legislation to protect the fishery. Containment of instream work is mandated in the legislature.

Calgary Bow River Instream Work Updates May 05 2017

Calgary Bow River Instream Work Sites

The 2013 Flood caused considerable damaged to the Bow River banks, instream infrastructure and changes to the footprint of the river. Over the past four years and into the future river banks will be stabilized and infrastructure redeveloped or replaced. In addition new bridges and river access will be built to support the ever increasing diversity of the city.

Each year there are two ” Windows of Opportunity” for instream work to be completed. April 6 to April 30 and July 15 to September 15. The main purpose of these restriction is to protect the spring spawning Rainbow Trout and fall spawning Brown Trout and restrict instream work during spring run-off. Each instream project is governed by Federal and Provincial statutes whereby there are policies and procedures that must be met to receive project approval. Although precautions are put in place to reduce the movement in sediment downstream, reduced viability can be expected over the duration of the work schedule. The following are a list of project that are planned for 2017:

Harvie Passage:

 This project managed by Alberta Transportation is a redevelopment of the high and low flow channels destroyed by the 2013 flood. Details of the project and timelines for instream work can be found at the following link Harvie Passage Redevelopment. The consulting engineers have indicated that the spring window of instream work will be completed on time:

“Instream work started today. The Contractor is working towards removing the cofferdams in the next week or so but the temporary diversion channel may not be blocked off till later. We are allowed to work instream till April 30th. The river will definitely be diverted back to the High Water Channel prior to April 30th

12 Street SE Bridge:

The New 12 Street S.E. Bridge spans the Bow River on the south side of St. George’s Island. It is an important link for vehicles and people, which provides access to and from 9 Avenue S.E. and Memorial Drive and access to the Calgary Zoo. The majority of the instream work is complete. The new bridge is scheduled to be completed in 2017. Project details can be found at the following link 12 Street SE Bridge. The old bridge footprint has been proposed as a new boat ramp in the Calgary River Access Strategy. Work on the boat ramp is planned to start in 2018.

17 Avenue SE  Bridge:

The City will be starting work on the bridge structures for the new 17 Avenue SE BRT Bridge adjacent to Cushing Bridge in early April. The first pieces of instream work will be the construction of a berm on the east side of the Bow River so the bridge structures can be built. Project details can be found at the following link 17 Avenue SE Bridge

Graves / Glenmore Bridge – Bank Stabilization 

Phase Two of this riverbank stabilization is taking place in 2017. To further stabilize the riverbank upstrem of the bridge, 110 meters of the bank will be shored up. Project details can be found at the following link Glenmore Bridge

Quarry Park – Fish Compensation Program

After the 2013 flood, The City completed several riverbank stabilization and rehabilitation projects at various locations along the Bow and Elbow Rivers. While necessary, these projects resulted in the loss of fish habitat which is now being replaced. Reestablishing the Quarry Park back channel will take place in 2017. Project details can be found at the following link Quarry Park – FCP

Elbow River – Bank Stabilization:

A stretch of the Elbow River bank at Riverdale Avenue will be stabilized in 2017. Project details can be found at the following link Riverdale

Calgary River Access Site Developments:

The Calgary River Access Strategy has identified six river access sites that will be developed in the next two years. A new boat ramp at Ogden Bridge and upgrades to Graves Bridge and West Baker Park access sites will start in 2017. Details of the site developments are detailed at the following link CRA Priority Sites


Not all construction sites will impact the Bow River all the time during the spring and summer instream work windows. Every precaution to protect the environment can be expected.

The referenced instream work sites will be updated as information become available.
