Mudpuppy Night in Oxford Mills

You can follow the water flow in Kemptville creek at - https://his.rvca.ca//StandardGraph_KemptvilleCreek_Hourly. - and see how it is changing. Last night the flow was below average, but only a few Mudpuppies had come up - sometimes it takes them a while to get moving after high water, and we think the large adults are downstream now, mating in their private under-rock way.

A Nopuppy Night with lots of water and no ice - 4 December 2020 - Canada: Ontario: Grenville County: Oxford-on-Rideau: Oxford Mills Dam, Kemptville Creek. (100m ard dam), 31B/13, 44.96486 N 75.67863 W TIME: 1959,2022-2049. AIR TEMP: 0.5C, overcast, Beaufort light air. HABITAT: brown-water creek at limestone flats below old milldam, water 1.5 C. OBSERVER: Frederick W. Schueler, Aleta Karstad Schueler, Oxford Mills Cub Scouts. 2020/241/b, visit (event). natural history, wade..., dipnetted, light, photo. covid-19 constrained Mudpuppy Night outing. Water level surging & flowing 10-15 cm above Vantage Point ledge - rapid equal flow through all spillways. Water is yellow & clear. NO:Necturus, NO:Lithobates, NO:Orconectes, NO:Teleostei, NO:Insecta seen from the bridge, wading E side, or from shore on W side. White billows of foam at sides of E & W spillways. Necturus (Mudpuppy) and Orconectes (Crayfish) captured last week released on E side so the Cubs could see them go. A very slight trace of drizzle falling intermittently. Aleta took photos of wet plants on W side - and we realize (after 45 years of visits) that the reason there's so much lichen on the bushes there is because of the moisture from the dam's spillways.

We're lucky we don't have Sea Lamprey control in Kemptville Creek - https://www.wcax.com//critics-concerned-vt-lamprey-poison/ - Decades & decades ago I read, in Readers Digest the testing of the lampricide - it killed ammocetes and didn't kill Smallmouth Bass - that was it. If we're going to control Lampreys we need a lampricide which doesn't kill other species.
